Cutaneous metastasis revealing a relapse of gastric linitis: Another case

INTRODUCTIONCutaneous metastasis from gastric cancer is a rare occurrence. The linitis gastric carcinoma accounts only 8.7% of all gastric cancers.PRESENTATION OF CASEWe report a case of female patient who was followed for linits cancer with peritoneal metastasis treated by six cycles of chemotherapy. After seventeen months of control, the relapse of the disease revealed by occurrence of cutaneous metastatsis.DISCUSSIONCutaneous metastasis from linit gastric is rare and the prognostic remains poor. The treatment is palliative.CONCLUSIONThis rare presentation should encourage the practitioners to biopsy any suspicion skin lesion.     

Unusual case of cavitary lung metastasis of esophageal cancer: A case report

Introduction and importanceCavitary lung metastases are rare. We experienced lung metastasis of esophageal cancer with a cavity, which is extremely rare.Case presentationA 69-year-old female diagnosed with thoracic esophageal cancer underwent radical esophagectomy. Pathological diagnosis was T3N0M0-pStageII. Cavitary lesion appeared in the lower lobe of the right lung 12 months after surgery. We suspected an inflammatory change and followed up strictly. On Computed tomography (CT) image 18 months after surgery, the cavitary lesion slightly increased in size, showing wall thickening and fluid inside. Fluid collection disappeared after antibiotic treatment. The patient was followed for 4 weeks without antibiotics and fluid collection reappeared. Cavitary lesion resection for the purpose of diagnosis was planned because malignancy could not be excluded, although the readministration of antibiotics was also considered. Thoracoscopic partial resection of the right lower lobe of the lung was performed. Histopathological examination showed squamous cell carcinoma which was similar in morphology to esophageal cancer. The final diagnosis was lung metastasis of esophageal cancer.Clinical discussionMetastatic lung cancer with a cavity is rare, accounting for approximately 4% of all cases. Moreover, Lung metastasis of esophageal cancer with a cavity is extremely rare.ConclusionsThe specimen collection, including total biopsy, should be aggressively performed when diagnosing cavitary lung disease in patients with a history of neoplastic disease.     

An unusual case caused by a common reason: Mondor's disease by oral contraceptives

INTRODUCTIONMondor's disease (MD) of the breast is a rare condition at breast clinics. We do not have enough data to establish its real prevalence. As a known data, most of the patients that were admitted to breast clinics are not breast cancer. Also MD is a rare entity and diagnosing this entity and informing the patient about it is very important. We present here this case to remind breast clinic practitioners that MD can be seen without trauma (neither surgical nor physical). Also clinical and radiological findings and the treatmentof the MD were discussed.PRESENTATION OF CASEA 35 year old woman was admitted our clinic with cutaneous breast retraction. She had no risk for thrombosis else using oral contraceptives. Mondor's Disease was diagnosed and supported by radiological findings. Rheumatologic and hematologic causes were also explored. Patient healed in four weeks only with non-steroidal anti-inflammatory drug.DISCUSSIONMondor's Disease is rarely related with breast cancer. This rare entity can be diagnosed with doubt and patient should be informed about it. Anti-coagulant treatment does not required if disease is idiopathic.CONCLUSIONMondor's Disease should be reminded at a patient with retracted breast skin.     

Oral malignant melanoma detected after resection of amelanotic pulmonary metastasis

INTRODUCTIONSolitary pulmonary metastasis from oral malignant melanoma is very rare.PRESENTATION OF CASEWe demonstrated a 84-year-old patient with a lung nodule that was diagnosed as malignant melanoma by video-assisted thoracoscopic resection. Because primary pulmonary malignant melanoma was extremely rare, the tumor was thought to be a metastasized from an occult primary lesion. A detailed physical examination revealed a black tumor in the oral cavity, and this was suspected to have been the primary. Resection of the hard palate tumor and dissection of the cervical lymph nodes were performed. The patient was simply followed up without further therapy at his request, and he died one year after surgery due to bleeding from a pleural metastasis of malignant melanoma.DISCUSSIONPrimary melanoma of the oral cavity is rare, accounts for 0.5% of all oral cancers, and 0.8–1.8% of all melanomas. Because of absence of symptoms in the early stage of the disease and the presence of the tumor in relatively obscure areas of the oral cavity, the diagnosis is unfortunately often delayed. In view of the rarity of primary lung melanoma, when lung tumor was diagnosed as malignant melanoma, detailed physical examination of the entire skin and mucosa including the oral cavity was necessary.CONCLUSIONOral malignant melanoma was very rare, but oral cavity should be examined when the pulmonary nodule was diagnosed as malignant melanoma.     

Prolonged Survival After Extracranial Metastasectomy From Synchronous Resectable Lung Cancer

Background:Combined resection of solitary synchronous brain metastases and non–small-cell lung cancer has been shown to be successful. Thus, we proposed combining the surgery of solitary, extracranial metastases, and resectable lung cancer.Methods:Between March 1987 and December 1994, surgery was performed on nine patients with non–small-cell lung cancer with synchronous, solitary, extracranial, or distant metastasis: adrenal (n = 5), cutaneous (n = 2), axillary lymph node (n = 1) and kidney (n = 1). Criteria for operating on these patients included: primary tumor that was locally resectable in a radical manner, non–small-cell histology, no preoperative evidence of N2 disease, complete resection of histologically proven metastasis, and absence of other metastases found with computed tomography or bone scan.Results:Resection of the primary tumor and solitary metastases was achieved in all patients. Primary tumor was always resected by lobectomy. No mortality or major morbidity was reported. Five-year survival rate was 55.6%. Five patients who had adrenal (n = 3), or skin (n = 1), or axillary (n = 1) metastases, survived more than 5 years. All N2 patients (n = 2) died.Conclusions:The presence of solitary, distant metastasis should not be considered, per se, a factor for denying surgery for locally resectable, non–small-cell lung cancer. Unexpected, prolonged survival was demonstrated in our limited series.     

An early orbital metastasis from breast cancer: A case report

IntroductionOrbital metastases from solid cancers are infrequent or underestimated, since they represent only 1–13% of tumors of the orbit. They are even less frequent in breast cancer and are rarely diagnosed. We report a case of an early diagnosed orbital metastasis from breast cancer to an extra ocular muscle.Case reportWe report the case of a 33-year-old female patient who presented, following the diagnosis of her breast cancer, headache, a progressive decrease in visual acuity of the right eye and diplopia. Brain imaging revealed a tissue process at the expense of the internal rectus muscle, which biopsy pointed to a secondary lesion of breast cancer.DiscussionExtraocular muscles are rarely infiltrated by metastasis from distant sites. They are mostly asymptomatic and suggest a systematic spread of the disease. The treatment is generally palliative and the prognosis is generally poor.ConclusionOrbital metastases from breast cancer are certainly rare but are associated with significant morbidity. In order to make a precise diagnosis and offer an appropriate treatment, healthcare professionals must remain vigilant in the face of any ophthalmological symptoms.     

Solitary thyroid metastasis from colorectal cancer: Case report

Introduction and importanceThyroid metastasis of colorectal cancer is rare and the patient with thyroid metastasis has no symptoms early in the disease course. On the other hand, evaluation of thyroid is not generally included in the routine follow-up of colorectal cancer. Therefore, the diagnosis of thyroid metastasis of colorectal cancer may be delayed.Presentation of caseChest computed tomography revealed a nodule on the right lobe of the thyroid in 53-year-old woman diagnosed with sigmoid colon adenocarcinoma. This nodule was identified having as increased metabolic activity by ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography and confirmed to be consisted of cystic and solid portions by ultrasonography. Fine needle aspiration cytology of the nodule revealed metastasis of colon cancer. The patient underwent laparoscopic anterior resection and a total thyroidectomy. The size of the thyroid tumor was 1.2 cm with free resection margin.DiscussionThe clinical features of thyroid metastasis from colorectal cancer are not typical. In addition, follow-up examinations of patients with colorectal cancer do not include imaging studies of the neck, so the diagnosis of thyroid metastases is delayed. The management strategies for thyroid metastasis from colorectal cancer include a total thyroidectomy without prophylactic neck lymph node dissection and chemotherapy. However, as the penetration of chemotherapeutic drugs into the thyroid is difficult, the effect on the thyroid is considered insignificant.ConclusionSurgical treatment should be considered for treatment of thyroid metastasis.     

Choroidal metastasis from early rectal cancer: Case report and literature review

INTRODUCTION

Choroidal metastasis from colorectal cancer is rare, and there have been no reported cases of such metastasis from early colorectal cancer. We report a case of choroidal metastasis from early rectal cancer.

PRESENTATION OF CASE

A 61 year-old-man experienced myodesopsia in the left eye 2 years and 6 months after primary rectal surgery for early cancer, and was diagnosed with left choroidal metastasis and multiple lung metastases. Radiotherapy was initiated for the left eye and systemic chemotherapy is initiated for the multiple lung metastases. The patient is living 2 years and 3 months after the diagnosis of choroidal metastasis without signs of recurrence in the left eye, and continues to receive systemic chemotherapy for multiple lung metastases.

DISCUSSION

Current literatures have few recommendations regarding the appropriate treatment of choroidal metastasis from colorectal cancer, but an aggressive multi-disciplinary approach may be effective in local regression.

CONCLUSION

This is the first report of choroidal metastasis from early rectal cancer. We consider it important to enforce systemic chemotherapy in addition to radiotherapy for choroidal metastasis from colorectal cancer.     

Recurrent gastric cancer metastasizing to the bone marrow: A case report of a rare presentation

IntroductionGastric cancer notoriously recurs post curative surgical resection. While there may be visceral metastasis to peritoneal surfaces, bone marrow involvement may also occur although with rarity. We present a case report of recurrent gastric cancer with bone marrow metastasis in a patient with no evidence of systemic disease on follow-up for two years post surgical resection. This case demonstrates the need of heightened clinical suspicion in these patients.MethodsWe reviewed the medical records of a patient who presented with metastatic gastric adenocarcinoma to the bone marrow two years post R0 subtotal gastrectomy with Roux-en-Y gastrojejunostomy without evidence of systemic disease on follow up for two years.ResultsLaboratory and imaging studies of the patient on presentation two years post R0 subtotal gastrectomy with Roux-en-Y gastrojejunostomy is as follows; elevated alkaline phosphatase (ALP) of 472 U/L, CT chest/abdomen/pelvis that showed multiple new sclerotic lesions throughout osseous structures suspicious for metastasis, PET/CT that showed many sclerotic lesions throughout the axial and appendicular skeleton, some FDG-avid and suspicious for active osseous metastasis. Bone marrow biopsy showed metastatic poorly differentiated carcinoma consisted with known history of gastric cancer.ConclusionGastric cancer has a high rate of recurrence post curative surgery. Despite the rarity of bone marrow metastasis, a high level of suspicion should be maintained in patients presenting with elevated ALP and evidence of pancytopenia post curative surgery.     

Prognostic value and impact of cerebral metastases in pancreatic cancer

Abstract

Background: Pancreatic cancer is a fatal disease most often diagnosed at an advanced stage. Most patients already suffer from irresectable tumor or distant metastases being most commonly found in the liver or the lung. However, cerebral metastases occur extremely rare.

Methods: We performed a retrospective analysis of our database to identify all patients diagnosed with pancreatic cancer and cerebral metastases who underwent surgical treatment in our department from January 2004 to November 2016.

Results: Only 0.2% (4 of 2492) were diagnosed with cerebral metastases. Two patients had surgical resection of the cerebral metastases. One patient underwent palliative radiation therapy and the fourth patient received only palliative therapy. Mean interval between initial diagnosis and development of brain metastases was 8.5 months (range 1–20). Mean survival period after diagnosis of brain metastases was 4.75 months (range 1–10).

Conclusions: Cerebral metastases of pancreatic cancer occur extremely rare. They are associated with an advanced tumor stage, commonly liver and lung metastases. All patients presenting with neurological symptoms, multifocal metastases, and significantly elevated CA 19-9 levels are suspicious of sustaining cerebral metastases and should undergo brain imaging.     

Metastatic Pulmonary Adenocarcinoma Deposit Arising Within a Cutaneous Basal Cell Carcinoma: A Case Report

Skin metastases are rare complications of internal malignancies, and most commonly arise from primary lung carcinoma (Brownstein and Helwig in Arch Dermatol 105:82–68, 1972). Metastatic cutaneous lesions have not previously been documented to arise within other skin tumours. We report our experience of a solitary pulmonary adenocarcinoma metastasis that arose within a pre-existing basal cell carcinoma in a patient with undiagnosed lung cancer. Immunohistochemistry was invaluable in confirming both the metastatic nature of the secondary skin lesion and its site of origin.     

Prognostic evaluation of intracranial metastasis in malignant melanoma

Background: Malignant melanoma (MM) is often reported as the third most common cause of intracranial metastasis (IM) after carcinoma of the breast and lung. Most patients with advanced MM will have widespread extracranial disease, but the majority will die from intracerebral spread. Methods: A retrospective review of 117 patients with documented IM from MM over the past 25 years was undertaken. Various factors (including age, race, sex distribution, primary lesions with Clark's level, Breslow's thickness, primary sites and staging at initial presentation, diagnosis of IM and its various treatment methods, survival data, and autopsy findings) were analyzed. Prognostic indicators were clarified from this analysis as a predictor of central nervous system (CNS) metastasis. An ideal treatment plan was also analyzed in order to predict a better survival. Results: Fifty-eight percent of patients were male; 42% were female. Seventy-one percent of the primary lesions were of Clark's level IV and V, with mean Breslow's thickness of 3.5 mm. Median time interval between the initial diagnosis and development of IM was 3.5 years. Complete surgical resection of the intracranial lesion in the brain resulted in the longest mean survival of 10.3 months, whereas mean survival for the group with no treatment was only 3 weeks. Patients with primary lesions of the head and neck had the lowest mean survival of 3.3 months, whereas those whose primary sites were unknown had the longest mean survival of 7.5 months. One- and 2-year survival were 9% and 3%, respectively. All but one of the 30 patients at autopsy were found to have visceral metastasis, namely of the lung, liver, and bone. Conclusion: An aggressive search for metastasis should be undertaken in patients at high risk of developing CNS metastasis, e.g., male, head and neck primary, Clark's level IV and V, Breslow's thickness of >3 mm, and presence of visceral metastases, mainly lung. A complete surgical resection should be attempted whenever possible, with adjunctive use of whole-brain irradiation, along with systemic chemotherapy for further control of recurrence and to prolong survival.Presented at the 46th Annual Cancer Symposium of the Society of Surgical Oncology, Los Angeles, March 18–21, 1993.     

Long-term survival after surgical resection of metachronous lung,brain and thyroid gland metastases from rectal cancer: A case report

Introduction and importanceBrain and thyroid metastasis from rectal cancer are uncommon, and the prognosis is poor. We report a patient with rectal cancer who developed metachronous lung, brain and thyroid metastases. Each metastatic lesion was curatively resected resulting in prolonged survival.Case presentationA 60-year-old male underwent rectal cancer resection, and the pathological diagnosis was tubular adenocarcinoma, pT2,pN1a,M0, pStageⅢa. Ten years after rectal resection, a solitary tumor in the left lung was detected. The tumor was resected thoracoscopically and the pathological diagnosis was metastatic tumor. Three years after the pulmonary resection, a solitary brain tumor was detected. The tumor was removed surgically, and the pathology was metastatic tumor. Two years after brain resection, a thyroid mass was detected. A partial thyroidectomy was performed and the pathology with immunohistochemical staining confirmed the thyroid lesion as a metastasis from the previous rectal cancer. Four years after thyroid resection (19 years after the initial rectal resection), he died from multiple lung and bone metastases.Clinical discussionColorectal metastases to the brain and thyroid gland are uncommon and are usually found with other distant metastases. Overall survival has been reported to be extremely poor. In this patient, lung, brain, and thyroid metastases were solitary and metachronous, and each lesion was curatively resected. Surgical treatment might contribute to prolonged survival.ConclusionThe treatment strategy of each patient should be individualized and depends on the timing of metastasis development. Selected patients with complete resection of metachronous metastases may have prolonged survival.     

Mesenteric inflammatory pseudotumor: A difficult diagnosis. Case report

IntroductionInflammatory pseudotumor (IP) is an uncommon benign neoplasm. It was first described in the lung but it has been recognized in several somatic and visceral locations. Mesenteric presentation is rare and its clinical presentation is variable but patients can be completely asymptomatic. Complete surgical resection is the only curable treatment. Rational follow-up protocols have not been established yet.Presentation of caseA 57 years-old man, with no relevant comorbidities and completely asymptomatic, apart from a lump on the right hypochondrium, was submitted to surgical resection of a large mesenteric mass. The preoperative Computed Tomography suggested gastrointestinal stromal tumor as the most probable diagnosis. Definitive histological examination of the completely resected surgical specimen confirmed the diagnosis of IP. The patient has been on follow-up for four years, without no evidence of recurrence.DiscussionThe preoperative diagnosis of IP may be difficult to establish mainly due to the lack of a typical clinical presentation. It is a rare entity, particularly in the adult population. These two aspects make it easier to neglect this entity in the differential diagnosis of an abdominal mass on asymptomatic adults. Although there are no formal guidelines on follow-up, close follow-up seems to be advisable in these patients as recurrence is frequent.ConclusionIP should be present as a possible differential diagnosis in an abdominal mass. Complete excision of the lesion can be curable but close follow-up seems to be required.     

A case of gastric cancer metastasis to the breast in a female with BRCA2 germline mutation and literature review

Introduction: Gastric cancer is a deadly disease. Common sites of distant metastasis of gastric cancer are the peritoneum, liver, lymph nodes, and lung. The breast is a rare site of metastasis in gastric cancer which occurs in males dominantly.

Patients and methods: Here, we report the first case of metastatic gastric cancer to the breast in a patient with the breast cancer 2 (BRCA2) germline mutation. A 34-year-old female was admitted to the hospital with dyspepsia and a palpable mass in the left breast. Gastric cancer was confirmed to be signet ring cell adenocarcinoma. The breast mass exhibited histological properties consistent with gastric cancer. Immunohistochemistry results showed the breast tumor was CDX-2 and CK20-positive, but ER-, CK7-, and GATA3-negative. The BRCA1 gene had a wild-type sequence, but a heterozygous variant was discovered in BRCA2 in exon 10 (c.1744A?>?C, p.T582P); the significance of this variant is unknown.

Results: The patient received palliative XELOX (capecitabine?+?oxaliplatin) with radiation therapy to the stomach. The breast tumor resolved completely, but the overall response was partial.

Conclusion: Gastric cancer metastasis to the breast is rare, but should be considered in young female patients with signet ring cell type gastric cancer.     

A case of duodenal intramural metastasis from gastric cancer

INTRODUCTIONHere, we report a case of duodenal intramural metastasis from gastric cancer, which is extremely rare.PRESENTATION OF CASEA 72-year-old man was admitted to our hospital with a chief complaint of lack of appetite in 2010. An endoscopic evaluation detected a Borrmann type 2 tumor occupying the lesser curvature of the gastric body and antrum, and pyloric stenosis. The patient underwent total gastrectomy. In an examination of the resected specimen, a type 2 tumor was identified in the middle gastric body and antrum, and a submucosal tumor was detected in the duodenal bulb. A histopathological examination demonstrated that the gastric tumor was not contiguous with the duodenal submucosal tumor. A microscopic examination demonstrated that the gastric tumor was a moderately to poorly differentiated adenocarcinoma and displayed lymphatic permeation. The duodenal submucosal tumor was also found to be an adenocarcinoma and was similar to the gastric tumor; therefore, we diagnosed the duodenal tumor as an intramural metastasis from gastric cancer.DISCUSSIONThe most common route of metastasis from gastric cancer involves hematogenous metastasis, lymph node metastasis, and peritoneal metastasis. Intramural metastasis from gastric cancer is rare and has been reported to be a variant of lymphogenic metastasis. The clinicopathological features of patients with duodenal intramural metastasis from gastric cancer are unclear because only one case of the condition has been reported.CONCLUSIONDuodenal intramural metastasis from gastric cancer is an advanced form of cancer, and we suggest that it should be treated with surgical resection followed by adjuvant therapy.     

A case report of testicular diffuse large B-cell malignant lymphoma with cutaneous metastasis: A rare entity

Introduction and importancePrimary testicular lymphoma (PTL) is a variety of extra-nodal lymphoma taking origin from testis. It accounts 5% of all testicular tumors. Metastasis may occur in contralateral testis, bone, central nervous system and rarely in skin. Herein, we present the case of testicular diffuse large B-cell malignant lymphoma with cutaneous metastasis.Case presentationA 60-year-old male presented with swollen painless solid right testis, with homolateral inguinal nodes. Testicular tumors markers were within normal range. Right radical orchidectomy was performed. Histopathological examination concluded to the diagnosis of Diffuse Large B Cell Lymphoma. Four weeks later, the patient presented alteration of general condition and multiples cutaneous centimetric lesions located in the right inguinal region. Biopsy of this lesion confirmed the diagnosis of metastases from the testicular lymphoma. The patient deceased three days later, before starting further treatment.Clinical discussionPrimary testicular lymphoma is a rare variety of testicular tumors. The prognosis is poor. Metastasis may occur in different sites such as contralateral testis, central nervous system, and skin. The prognosis is usually poor in the rare case of cutaneous metastasis.ConclusionPrimary testicular tumor is an aggressive rare variety of testicular tumors with poor prognosis. Cutaneous metastasis is rarely reported. Cutaneous lesions should be explored and suspected to be malignant. Early treatment with rapid multidisciplinary management is the key for adequate approach.     

Colorectal carcinoma and brain metastasis: Distribution,treatment, and survival

Background: Brain metastasis from colorectal cancer is rare. The present study reports the nature of this disease and analyzes factors correlated with survival in patients harboring such disease. Patients and Methods: One hundred patients diagnosed between 1980 and 1994 with metastatic brain tumors secondary to colorectal adenocarcinoma were retrospectively reviewed. Of these patients, 36 underwent surgery, 57 underwent radiotherapy alone, and the remaining seven received steroids. Results: The most common primary sites were the sigmoid colon and rectum (65%). Brain metastases with concomitant liver and/or lung metastases were seen more frequently than brain metastases alone. The median interval between the diagnosis of primary cancer and the diagnosis of brain metastasis was 26 months (95% confidence interval =22–30). The median survival time after the diagnosis of brain metastasis was 1 month for patients who received only steroids, 3 months for those who received radiotherapy (p=0.1), and 9 months for those who underwent surgery (p<0.0001). The extent of noncerebral systemic disease was not correlated with survival (p>0.05), but early onset of brain metastasis was significantly associated with poor prognosis (p=0.04). Conclusion: Surgical removal of colorectal metastatic brain lesions results in significantly increased survival time, regardless of the status of the noncerebral systemic disease.     

Metachronous mediastinal lymph node metastasis from ascending colon cancer: A case report and literature review

IntroductionMetachronous mediastinal lymph node metastasis without pulmonary metastasis is extremely rare in colorectal cancer, which makes the clinical diagnosis difficult and treatment strategy unclear.Prsentation of caseA case was a 59-year-old man, who had undergone right hemicolectomy for ascending colon cancer 2 years and 8 months previously, presented with enlarged mediastinal lymph nodes. ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography revealed FDG was accumulated only into the mediastinal lymph nodes. Serum carcinoembryonic antigen (CEA) level was within the normal range. Six months later, the size and FDG uptake of the mediastinal lymph nodes had increased. We assumed a possibility that the mediastinal lymph nodes were metastasized from ascending colon cancer and so performed thoracoscopic-assisted resection of the mediastinal lymph nodes. Histopathological analysis revealed the resected lymph nodes were filled with moderately differentiated adenocarcinoma and a diagnosis of mediastinal lymph nodes metastasis from previously-resected ascending colon cancer was made. The patient was postoperatively followed for more than 1 year and 8 months without any sign of recurrence.DiscussionOnly 7 cases of metachronous mediastinal lymph node metastasis from colorectal cancer, including our case, have been reported in the English literature. It is difficult to clinically diagnose mediastinal lymph node metastasis.ConclusionWe report a rare case of metachronous mediastinal lymph node metastasis from ascending colon cancer with literature review. If the mediastinal lymph nodes are enlarged after colorectal cancer resection, we need to make a treatment strategy as well as a diagnostic approach considering the possibility of mediastinal lymph node metastasis.
