A small early carcinoma of the stomach with extra-perigastric lymph node metastasis: A case report

An early gastric carcinoma, measuring 1.7×0.6 cm, had already metastasized to the extra-perigastric lymph node in a 71 year old symptom-free man. Radiographic and endoscopic studies showed a small depressed lesion on the lesser curvature of the antrum and histology of the biopsied specimen revealed a well differentiated adenocarcinoma. Under the diagnosis of IIc type intramucosal carcinoma, partial gastrectomy and wide lymph node dissection was performed. Pathologic study of the resected specimen showed that the cancer cells had invaded the submucosa at an area via a lymphatic vessel and that only lymph node along the common hepatic artery was involved.     

Dermatofibrosarcoma protuberans with regional lymph node metastasis: a case report

The case of a 21-year-old man with dermatofibrosarcoma protuberans of the scalp that spread to deep cervical lymph nodes is presented. Available literature is reviewed, and the infrequency of metastasis is discussed. Since cases of metastases almost always involve recurrent lesions, the importance of wide and deep resection in the initial operation cannot be overemphasized.     

Inguinal lymph node metastasis of bladder carcinoma ten years after cystourethrectomy: a case report

A 79-year-old man had undergone radical cystourethrectomy for bladder carcinoma in January, 1989. Pathological report was Small cell carcinoma (SCC) > transitional cell carcinoma (TCC), G2 > G3, pT4 (prostate), ew (-). Ten years later, follow-up computed tomography (CT) revealed swollen left inguinal lymph node in October 1998 and lymph node dissection was performed in January, 2000. The pathological report showed TCC, G2. Left inguinal lymph node metastases appeared again in January, 2001. Chest X-ray films showed multiple lung metastases in March, 2001. Three couses of MVAC (methotrexate, vinblastine, doxorubicin cisplatinum) chemotherapy had been performed since September, 2001 but were in effective. Papillary tumor was observed at external urethral meatus in September, 2002 and the biopsied specimens showed TCC, G1 > G2, pathologically. Finally he died of respiratory insufficiency in January, 2003. It is suggested that the recurrent TCC tumor in the urethral remnants might metastasize into the inguinal lymph nodes.

Goblet cell carcinoid of the rectum with lymph node metastasis: report of a case

We report an unusual case of goblet cell carcinoid (GCC) of the rectum. A 75-year-old man was admitted to our hospital with anal bleeding, and a hard tumor was felt on the anterior wall of the lower rectum during rectal examination. We performed colonoscopy, and found a 30-mm type 2 tumor in the lower rectum and anal canal. Histological examination of biopsies revealed rectal adenocarcinoma. Based on these findings, we diagnosed rectal adenocarcinoma and performed Miles’ operation with lymph node dissection. Histological examination revealed an invasive lesion composed of signet-ring-like cells. Seven regional lymph node metastases were seen microscopically. The tumor produced copious mucin, which was stained with Alcian blue. Immunohistochemistry was positive for synaptophysin, chromogranin A, CD56, carcinoembryonic antigen, p53, Ki-67, E-cadherin, and cytokeratin 20. The final diagnosis was GCC of the rectum.     

Adrenal metastasis of lung adenocarcinoma with unusual sites of lymph node metastasis and concomitant renal cell carcinoma: a case report

A 58-year-old male presented to a clinic with general weakness. Right adrenal tumor was found by computed tomography and he was referred to our hospital. Imaging studies revealed right adrenal tumor (8 cm) with marked swelling of surrounding lymph nodes and synchronous left renal tumor (2 cm) that was weakly enhanced by contrast media. Needle biopsy of the left kidney proved to be clear cell type renal cell carcinoma (RCC) and the preoperative diagnosis was left RCC and right primary adrenal cancer with lymph node metastasis. We performed right adrenalectomy, lymph node dissection and left radical nephrectomy. Pathological findings of right adrenal tumor and lymph nodes were both metastatic adenocarcinoma, which was not consistent with RCC or adrenal-derived carcinoma. Then, we extensively reviewed preoperative radiological examinations and found a small lesion in the left upper lung. This lesion was attached to the mediastinal shadow and there was no obvious lymph node swelling around this lesion. According to pathological findings and an elevation of carcinoembryogenic antigen, the adrenal lesion was diagnosed as adrenal metastasis of lung adenocarcinoma.     

Malignant cystosarcoma phyllodes with lymph node metastasis —A case report—

A case of malignant cystosarcoma phyllodes with metastasis in the interpectoral lymph node (Rotter's) is presented in this paper. To the author's best knowledge, this is the first case in Japan on this disease, with lymph node metastasis. Although the surgical management of the disease has not yet been standardized, radical or modified radical mastectomy is thought to be the appropriate procedure.     

Trichilemmal carcinoma of the axilla with regional lymph nodes metastasis: A case report

Introduction and importanceTrichilemmal carcinoma is a rare malignant cutaneous adnexal neoplasm of hair follicles originating from the external root sheath epithelium. The diagnosis is rarely made clinically and is still challenging for an experienced pathologist.AimTo report a rare case of trichilemmal carcinoma presenting as a right axillary mass with regional lymph nodes metastasis and was treated with wide local excision in the General Surgery Department Jordanian Royal Medical Services (JRMS), Jordan.Case presentationA 45-year-old presented with a right axillary mass of six-month duration. Physical examination revealed a hyperemic, thickened skin of both armpits with a palpable 5-cm mass in the right axilla. He underwent an excisional biopsy of the right mass. Histopathologic examination revealed a malignant adnexal skin tumour with foci of trichilemmal-type keratinisation. It was excised with adequate margins.Clinical discussionTrichilemmal carcinoma usually occurs on the forehead, scalp, neck, back of hands and trunk. These neoplasms are rare lesions presenting as locally aggressive, low-grade carcinomas and have the potential for nodal involvement and distant metastasis. Therefore, the establishment of a correct diagnosis is vital to guide the treatment plan. Wide excision with adequate tumour-free margins is considered a curative treatment and offers a successful outcome.ConclusionMalignant cutaneous adnexal tumours are one of the most challenging subjects of dermatopathology. Surgical excision is always required to establish a definitive diagnosis and differentiation subtypes. Trichilemmal carcinoma is a relatively rare tumour, mainly when located in the axilla.     

Collision metastasis of breast and thyroid carcinoma to a single cervical lymph node: report of a case

We herein report a rare case of collision lymph node metastases of breast and thyroid carcinomas. A 49-year-old female had undergone an extensively radical mastectomy of the right breast for inflammatory breast cancer at our hospital. Eleven months later, she presented with enlarged lymph nodes in her right lateral neck and multiple nodules in bilateral thyroid lobes. The patient underwent total thyroidectomy and radical dissection of the bilateral cervical lymph nodes. A histological examination showed multiple foci of papillary thyroid carcinoma (PTC) in the bilateral lobes. Surprisingly, concurrent metastases of breast carcinoma and PTC were shown in one of the lymph nodes from the right jugular region. This rare case of collision metastasis and the related literature are discussed.

Noninvasive intraductal papillary mucinous neoplasm with para-aortic lymph node metastasis: report of a case

Intraductal papillary mucinous neoplasms (IPMNs) with an invasive carcinoma component are categorized as minimally invasive or invasive. The prognosis after resection of minimally invasive IPMNs has been reported to be similar to that after resection of noninvasive IPMNs. We report a case of noninvasive branchduct IPMN with multiple lymph node metastases, including para-aortic node involvement, treated successfully by distal pancreatectomy with lymph node dissection. The patient, a 72-year-old man, had two multilocular cysts in the pancreatic body, 22 mm and 14 mm in diameter, respectively, communicating with the main pancreatic duct. The primary tumor and nodal metastases had similar patterns of mucin expression. The primary tumor contained a region of carcinoma in situ (CIS) without histological evidence of stromal invasion; thus, it was diagnosed as minimally invasive carcinoma. We report this case to emphasize two important points: first, even small branch-duct IPMNs without any indications for resection can have a component of CIS or more advanced disease; and second, even branch-duct IPMNs without any apparent invasive component can be aggressive and spread to the lymph nodes. Therefore, nodal status should be assessed carefully in every patient, even if the primary IPMN is not advanced.     

Clinicopathological features of mucosal carcinoma of the stomach with lymph node metastasis in eleven patients

Of 568 patients with mucosal carcinoma of the stomach, only 11 (1.9 per cent) had a lymph node metastasis. The clinicopathological findings in these 11 patients are reviewed. Diameters of the lesions were over 2.0 cm. Seven were located in the body of the stomach and four in the antrum. Nine showed depressed lesions comprised of poorly differentiated adenocarcinoma and two were classed as elevated lesions consisting of well and moderately differentiated adenocarcinomas. There were six with accompanying peptic ulcers, all of which revealed depressed lesions with poorly differentiated adenocarcinoma. Metastases to proximal perigastric lymph nodes were found in eight while there were three with involvement of distant lymph nodes. All patients were surgically treated and all are doing well except for one who died of hepatic failure one month after operation. We recommend that the standard operation with lymph node dissection is essential, even in cases of mucosal carcinoma.     

A rare case of a laryngeal leiomyosarcoma with a lymph node metastasis

IntroductionLeiomyosarcoma is a rare mesenchymal tumor that originates from smooth muscle cells. Head and neck LMSs represent only 3% of all leiomyosarcomas with less than 50 cases of laryngeal LMS reported in the literature till now.Case presentationWe report a case of 50-year-old male presented at our ENT department for a chronic hoarseness. Clinical examination investigations found small submucosal lesion in the right vocal cord. Treatment consisted of CO2 Laser excision of the lesion. The evolution was marked by the appearance of a tumefaction in the left submandibular region and a severe dyspnea requiring an emergency tracheotomy. Paraclinical examination investigations found a supraglottis–glottis-subglottis tumor. A total laryngectomy with bilateral functional neck dissection was performed and the histopathological examination found a laryngeal leiomyosarcoma.ConclusionLMS of the larynx a very rare malignancy. The accurate diagnosis is histological. Surgery is the mainstay of treatment. Its prognosis is correlated to local recurrence and distant metastases.     

Inguinal lymph node presenting as the delayed site of metastasis in early stage endometrial carcinoma: Case report

IntroductionInguinal lymph nodes are the frequent sites of metastasis for malignant lymphoma, squamous cell carcinoma of anal canal, vulva and penis, malignant melanoma and squamous cell carcinoma of skin over lower extremities or trunk. Anatomically, endometrial carcinoma is less likely to spread to the superficial or deep inguinal lymph nodes, thus metastatic involvement of these lymph nodes can easily be overlooked.Case presentationHere-in we report a case of a 65-year old Saudi morbid obese female, who presented with left inguinal lymphadenopathy as initial delayed site of metastasis almost 19 months after the initial treatment for FIGO IA endometrial carcinoma. Patient underwent left inguinal lymph node dissection. Histopathology confirmed metastatic endometrial adenocarcinoma, positive for cytokeratin (CK-7), estrogen receptor (ER) and progesterone receptors (PR), negative for CK-20 and CDX2. Following the post-surgery recovery, she was given extended field radiation therapy to para-aortic, pelvis and bilateral inguinal lymph nodes with concurrent cisplatin chemotherapy followed by high dose rate brachytherapy.ConclusionInguinal lymph nodes as delayed site of metastasis in early endometrial carcinoma is extremely rare entity. Incorporation of FDG-PET during the preoperative screening of inguinal nodes may be helpful. The impact of lymph node dissection and adjuvant radiation therapy on survival needs to be established.     

Pancreaticoduodenectomy for hepatic portal lymph node metastasis after hepatic resection for hepatocellular carcinoma: A clinical case report

IntroductionIn 2018, Hepatocellular carcinoma (HCC) was predicted to be the sixth most commonly diagnosed cancer. Extra-hepatic metastasis due to HCC is a poor prognostic factor, depending on the stage of the disease.Presentation of caseWe report a case of a 52-years old male who had undergone Segment 5 (S5) hepatectomy for HCC of 4.7 × 2 cm. Transcatheter arterial chemoembolization (TACE) four times postoperatively was performed based on a preoperative diagnosis of a recurrent tumour at the S1. After 2 years, the solitary tumour (7.5 × 2.5 × 3.5 cm) is located behind the right lobe of the liver and the head of the pancreas. The tumour was abnormally supplied with blood from the superior mesenteric artery (SMA) and the gastroduodenal artery (GDA). The patient was underwent pancreaticoduodenectomy (PD) to remove a large tumour. Postoperative pathology and immunohistochemical staining showed metastatic HCC. There was no tumour recurrence after 6 months.DiscussionThe organs in the body that liver cancer cells most often spread to are the lungs (44%), the portal vein (35%), the hepatobiliary ganglion (27%), and a small number of cases of bone, eye socket, bronchus metastases. Otherwise, recurrence of lymph nodes (LNs) after hepatectomy for HCC is very rare.ConclusionsHCC can metastasize to the hepatic pedicle LN after hepatectomy and maybe confused with recurrent liver tumours in the S1. Indications for PD are feasible for solitary metastatic at peri-pancreas. Pathology incorporating immunohistochemistry can determine the origin of metastases.     

A case of a superficial carcinoma of the esophagus with isolated lymph node metastasis around the abdominal aorta

Superficial carcinoma of the esophagus with isolated para-aortic lymph node metastasis is quite rare. A 56-year-old female demonstrated a type 0-IIa+IIb lesion in the middle thoracic esophagus on endoscopic examination. Enhanced computed tomography and positron emission tomography demonstrated two swollen lymph nodes on the right side of the inferior vena cava, but did not demonstrate either a primary lesion or regional lymph node metastasis. A retroperitoneal videoscopic lymph node biopsy was thus performed, and the histopathological diagnosis was metastasis of squamous cell carcinoma. Induction chemotherapy was administered with cisplatin/5-FU, and followed by definitive chemoradiotherapy with cisplatin/5-FU plus 60 Gy radiation. The patient showed satisfactory responses in both the primary and metastatic lesions. This is the first case report describing superficial carcinoma of the esophagus with isolated lymph node metastasis around the abdominal aorta. A precise histological diagnosis of the lymph node is quite important in such cases, and an adequate curative effect can be expected.     

Giant leiomyosarcoma of the rectum with lymph node metastasis: A case report and review of the literature

IntroductionLeiomyosarcoma of the gastrointestinal tract is very rare, with a reported frequency of less than 0.1% of all malignancies of the colorectum. It is important to diagnose leiomyosarcoma definitively by immunohistochemical profiling of smooth muscle actin, desmin, and CD34. True leiomyosarcoma of the colorectum diagnosed by immunnohistochemical profiling is extremely rare that only 13 reports have been published in reviews of resected gastrointestinal mesenchymal tumors after 1998. In addition, lymph node involvement is rare in patients with leiomyosarcoma. Herein we report an aggressive case of LMS in a rectosigmoid lesion with lymph node metastasis.Case presentationA 76-year-old woman visited our hospital complaining of intermittent anal bleeding that had lasted 5 months. Image studies aiming at examining the cause of her anal bleeding revealed a tumor located between the right ovary, uterus, and the rectosigmoid. Histopathology of biopsied materials from the colonoscopy suggested a malignant tumor of mesenchymal origin. Surgical resection was performed with curative intent. The tumor was diagnosed as leiomyosarcoma by pathological examination. Moreover, one of the 31 regional lymph nodes retrieved was metastasized by leiomyosarcoma. Eight months later, follow-up CT scans revealed multiple recurrent lesions in the liver and peritoneum. Despite systematic chemotherapy, she deceased 12 months after the surgery.ConclusionIt is crucial to diagnose leioyosarcoma precisely based on immunohistochemistry, and thereby distinguish it from GIST. Although lymph node metastasis is rare, lymphadenectomy appears to be important for high-risk LMSs to perform R0 resection. Further investigation on leiomyosarcoma cases so far is required to establish standard treatment strategies.
