Bladder leiomyoma in pregnancy: a case report.

We herein report a rare case of an asymptomatic bladder mass seen during pregnancy in a young woman. A hypogastric mass was detected at antenatal checkup in the 7th month of pregnancy. The mass increased in size as the pregnancy went to term. Three months after normal delivery, she underwent surgery and a tumor arising from the bladder wall was excised completely. Histology showed a symplastic leiomyoma.     

Re-irradiation to prevent ectopic bone formation after major hip surgery

Ectopic bone formation may occur after total hip arthroplasty, but fortunately most patients are asymptomatic. Both pre-operative and post-operative radiotherapy are effective in prevention of ectopic bone formation. In the few patients who needed re-operation, we found that re-irradiation is possible and safe. This case report presents our experience with single dose reirradiation of the hip in an attempt to prevent post-operative ectopic bone formation.     

Lung cancer mimicking as pregnancy with pneumonia

SUMMARY: Lung cancer that presents with secretion of beta HCG is rare. We report a case of a young female patient who presented with symptoms of pneumonia and was found to have a positive pregnancy test. With non-resolution of the consolidation and progression of her symptoms she subsequently was found to have large cell lung cancer with ectopic beta HCG secretion. Ectopic production of a variety of hormones such as ADH, parathyroid hormone, ACTH, insulin-like growth factor thus leading to presentation as endocrine syndromes in patients with lung cancer is well known. The presentation of lung cancer mimicking as pregnancy has not been previously reported. This case illustrates the importance of considering the possibility of paraneoplastic secretion of beta HCG in female patients who have a positive pregnancy test in an appropriate clinical setting. This may prevent a delay in the diagnosis and treatment of malignancy in young women.     

Transvaginal ultrasound diagnosis of a live twin tubal ectopic pregnancy

A case of live twin tubal ectopic pregnancy diagnosed by transvaginal ultrasound is presented. This is a rare occurrence and we have calculated the incidence to be ~ 1:125 000 pregnancies. There have been more than 100 case reports of twin tubal ectopic pregnancy but only four previous reports where two foetal heart motions have been visualized. The introduction of high-resolution transvaginal ultrasound has resulted in earlier diagnosis of ectopic pregnancy and contributed to the decrease in morbidity that has occurred over recent years.     

Twin ectopic pregnancy 10 years after permanent sterilization

An ectopic twin pregnancy was reported in a 37‐year‐old woman with a history of tubectomy for permanent sterilization 10 years earlier. Ectopic pregnancy is common, but twin ectopic pregnancy is a rarer case.     

A mediastinal germ cell tumor mimicking an ectopic pregnancy

The objective is to report the case of a 36 year-old female with a primary mediastinal germ cell tumor mimicking an ectopic pregnancy. The patient under birth control pill presented, at seven weeks of amenorrhea, a β-human chorionic gonadotropin (β-hCG) level of 850 UI and uterine vacuity with left lateral uterine heterogeneous mass but no bleeding and no pain. She received left adnexectomy, uterine curettage and further treatment by methotrexate because of persistent high β-hCG markers. Computed tomography scan finally permitted to discover a voluminous anterior mediastinal tumor. We may recommend investigating patients with a simple chest X-ray that present with persistent increased β-hCG despite efficient ectopic pregnancy treatment.     

Advanced mucinous adenocarcinoma in pregnancy

The incidence of masses in pregnancy is estimated to occur in 1/81 to 1/2,500 pregnancies. The development of colorectal carcinoma during pregnancy is a more rare event, with less than 30 cases above the peritoneal reflection reported in the last 70 years. The differential diagnosis of mucinous adenocarcinoma of ovarian vs. gastrointestinal origin is often difficult. We report a pregnant patient affected by advanced colorectal cancer, who presented with an asymptomatic unilateral adnexal mass on ultrasound. A 28-year old woman was referred to our hospital after a routine ultrasound examination at 26 weeks gestation showing a right adnexal mass. At elective exploratory laparotomy, the patient was found to have metastatic mucinous adenocarcinoma. Diagnostic and treatment choices of such a cancer in a pregnant patient were explored. The final diagnosis of colorectal cancer was made only at the time of a subsequent emergency laparotomy. The goal of an obstetrician/gynecologist and other care givers of pregnant patients, is to achieve a healthy mother and child. Unfortunately, physicians may unwillingly sacrifice the health of the mother by denying or delaying her procedures or treatments simply because she is pregnant. It is especially important in the case of adnexal masses and their related pathology, due to the difficulty in detection and management of such cases during pregnancy, that doctors actively assume the responsibility of assuring that pregnant patients receive the proper care they need.     

Synovial sarcoma: An unexpected ultrasound finding in a post-partum patient

A 20-year-old patient presented after an uneventful pregnancy and delivery with an asymptomatic soft-tissue mass behind her knee with the clinical features of a ganglion or Baker's cyst. An ultrasound scan demonstrated a well-defined but solid mass with prominent vascularity. The mass was noted to increase in size prior to surgery. The pathological diagnosis was that of a synovial sarcoma grade 2, a rare malignant mesenchymal neoplasm with a serious prognosis.     

Surgical Treatment of Retrosternal Goitre

This study aims to evaluate surgical approaches to the management of retrosternal goitre. Between 2004 and 2014, 35 patients (eight males; mean age 67.4 ± 10.9 years) with retrosternal goitre (mainly right-sided in 9, left-sided in 14 and bilateral in 12) underwent surgery. A palpable neck mass was found in 11 (31.4%), stridor in 10 (28.6%) and thyrotoxicosis in 4 (11.4%) cases. 4 (11.4%) patients were asymptomatic. Tracheal compression was detected radiologically in 27 (77.2%) patients with deviation in 18 (51.4%). A collar incision was performed in 34 patients, 6 (17.1%) of whom required additional sternotomy, 1 (2.9%) was assisted by an anterior mediastinotomy. 1 (2.9%) had a right lateral thoracotomy. There was no operative mortality. Transient vocal changes occurred in 3 (8.6%) patients, recurrent laryngeal nerve palsy in 3, atrial fibrillation in 2, and wound complications in 2 (5.7%). Hospital stay ranged from 2 to 12 days (5.5 ± 2.0). Multinodular goitre was found in 33 patients, diffuse goitre in 1 and ectopic thyroid in 1. The average vertical length of goitres in the collar incision group was 7.6 cm compared to 10.6 cm in the sternotomy group. The average weight of specimens was 156.3 g in patients with collar incisions and 307.5 g in the sternotomy group. Removal of retrosternal goitre is more commonly performed via a cervical collar incision with mandatory availability of sternotomy. Radiological measurement of craniocaudal length may predict the risk of sternotomy. Surgical outcomes are not affected by surgical approach.     

A case of ectopic breast cancer with a literature review

A 63-year-old woman was referred to our hospital because of a right axillary nodule in 2004. Physical examination showed a spherical nodule measuring 0.5 cm in diameter in the right axilla. No mass was palpable in either breast. Mammograms were normal. Ultrasonography revealed a subcutaneous hypoechoic mass 0.7 mm in maximum diameter in the right axilla. The patient underwent an excisional biopsy. Histological examination revealed an invasive ductal carcinoma (scirrhous carcinoma) in ectopic breast tissue. The patient subsequently underwent a wide local excision of the tissue surrounding the biopsy scar, with axillary lymph node dissection. Histologically, no residual tumor or nodal metastasis was found. Postoperatively, she received endocrine therapy and remains well, without any evidence of recurrence 4 years 10 months after operation. Cancer of the ectopic breast tissue is rare, and most cases present as a solitary axillary mass. Long-term outcomes remain unclear. We present a case of breast carcinoma in the axillary ectopic mammary gland and summarize the clinical features of 94 cases, including ours, in Japan. We also compare long-term survival between ectopic breast cancer and usual breast cancer according to TNM T stage and lymph node metastasis.     

Phyllodes tumor arising in ectopic breast tissue of the axilla

We examined a 31-year-old woman with a solid mass in her left axilla. Physical examination and ultrasonography confirmed a 2 cm well-defined mass. Fine needle aspiration biopsy suggested fibroadenoma of breast. Excisional biopsy revealed benign phyllodes tumor of the ectopic breast tissue. Phyllodes tumor in ectopic breast tissue is an extremely rare occurrence. Only nine cases have been reported, including tumors of the vulva, inguinal region and axilla. This is the second case in the axillary region.     

An Atypical Rare Case of Extracranial Craniopharyngioma

We present a case of a purely extracranial, infrasellar craniopharyngioma that initially presented as a mass in nose and nasopharynx. Craniopharyngiomas are usually located within the sella. Purely infrasellar craniopharyngiomas have only rarely been reported in the literature. A 55-year-old man presented with 8-month history of progressive headache and epistaxis. Rhinoscopy revealed polypoidal mass in both the nasal cavities and nasopharynx. Pre-operative biopsy suggested Craniopharyngioma. A battery of tests necessary for the diagnosis of Craniopharyngioma was done which excluded other possibilities. Surgical resection was done and histopathology thereafter was confirmatory of Craniopharyngioma. Adjuvant radiotherapy was given to the patient. The patient is doing well. The Rathke’s pouch arises from the roof of the primitive mouth and grows toward the brain at the fourth week of gestation. Normally, it loses its attachment with the stomadeum completely by the eighth week of gestation. The craniopharyngeal canal (CPC) extends from the floor of the sella to the vomer and may rarely give rise to ectopic craniopharyngiomas. This case shows that such ectopic tumors may arise anywhere along the CPC. We are documenting this case as an atypical rare case of craniopharyngioma probably originating from tooth primordia.     

Presacral myelolipoma in a patient with colon carcinoma.

Myelolipoma is an uncommon benign tumor, composed of an admixture of adipose tissue and hematopoietic cells, usually discovered within the adrenal glands. Extra-adrenal myelolipomas are rare and approximately half of the reported cases were presacral. We report a case of an asymptomatic presacral myelolipoma measuring 9x8x7 cm, incidentally found in a 71-year-old woman with a stenosing colon cancer. Ultrasonography, computed tomography and magnetic resonance imaging of the presacral mass evidenced a well circumscribed tumor with heterogeneous features due to a nonuniform composition. Surgical excision of the mass was performed.     

Sarcoidosis of the pineal gland: an unusual presentation of neurosarcoidosis

Introduction Sarcoidosis is an inflammatory disease characterized by noncaseating granulomas that is rarely found as primary CNS pathology. We report an unusual case of sarcoidosis involving the pineal gland with radiographic, histopathology, and clinical data. Case report A 45-year-old man without evidence of systemic sarcoidosis presented with a history of gradual onset of blurry vision and diplopia that progressed over 3 months. MR imaging demonstrated an enhancing mass in the pineal region. A suboccipital craniotomy was performed with resection of the mass through a supra-cerebellar infratentorial approach. Histopathologic analysis did not reveal a pineoblastoma but instead revealed noncaseating granulomas within the pineal gland. Extensive hematologic laboratory examinations, cerebral spinal fluid studies, and cultures for infection were all negative. This mass lesion was diagnosed as solitary neurosarcoidosis of the pineal gland, without dissemination. The patient was treated with steroids and at 4-year follow-up is asymptomatic with an unremarkable MRI scan. Conclusion This is an unusual case of pineal sarcoidosis mimicking a tumor with associated MRI, CT and histopathologic findings reported together. Although rare, sarcoidosis of the pineal gland should not be excluded from a comprehensive differential diagnosis of an enhancing pineal region mass.     

A case of icteric hepatoma with laryngeal metastasis and coexisting pancreatic cancer

An autopsy case of a hepatocellular carcinoma with an omental mass, a laryngeal metastasis, and a coexisting pancreatic head carcinoma is reported and the diagnostic problems it presented is discussed. An obstructive jaundice was treated by transhepatic drainage, and was proved to be caused by the invasion into the bile duct of the hepatocellular carcinoma and not the pancreatic head tumor. An asymptomatic, papillomatous growth from the metastasis of the hepatocellular carcinoma was found in subglottic region, an extremely rare type of metastasis .     

Mucoepidermoid carcinoma of the stomach

A rare case of mucoepidermoid carcinoma of the stomach in a 70-year-old man is reported. The protruded mass with central depression resembled a submucosal tumor, located on the posterior wall of a part of the cardia, fornix, and upper corpus. Histologically, submucosal ectopic glands composed of columnar cells, mucus-producing cells that closely resemble gastric epithelium, and ciliated epithelium were observed. The tumor consisted of an admixture of cuboidal, columnar cells, mucus-producing cells, singled or pseudostratified ciliated epithelium, and squamous metaplastic cells. The tumor cells were intimately continuous with the submucosal ectopic glands. Gradual transition between tumor cells and epithelium of submucosal ectopic glands was recognized. It is supposed that mucoepidermoid carcinoma of the stomach in this case derived from preexisting submucosal ectopic mucous glands of the stomach.     

Successful Completion of Pregnancy in a Patient With Chronic Myeloid Leukemia Without Active Intervention: A Case Report and Review of the Literature

The management of patients with chronic myeloid leukemia (CML) during pregnancy is a matter of continued debate. We present a 21-year-old woman in whom CML was diagnosed during early pregnancy. Because the patient was asymptomatic and desired to carry the pregnancy to term while minimizing fetal exposure to medication, she was observed with no therapy for the duration of her pregnancy. The white blood cell count showed a slow downward trend throughout her pregnancy. She delivered a healthy baby and breast fed for a time before initiating therapy for CML. We reviewed the published case reports of women who had a pregnancy occur in the setting of treatment with imatinib. Given the adverse effects of fetal exposure to imatinib as treatment for the mother with CML, close observation might be an option for selected patients who are diagnosed with CML while pregnant and who have minimal clinical manifestations of CML.     

Epididymal metastases as the first sign of a colon cancer recurrence

Metastastic tumours involving the epididymis are rare and most often found in patients with disseminated disease. It is even more unusual when the metastasis of the epididymis is the first sign of tumour recurrence. We report a case of an asymptomatic recurrent colon carcinoma presenting as metastasis in the epididymis. Although metastatic cancer presenting as an intra-scrotal mass is extremely rare, it should be considered as a possibility in patients who present with a mass involving the testicle or epididymis.     

Ectopic,retroperitoneal adrenocortical carcinoma in the setting of Lynch syndrome

Adrenocortical carcinoma (ACC) is rare within the adult population. Ectopic ACC proves even rarer. This variant is formed by cortical fragments arrested during embryologic migration. ACC is also known to be associated with several genetic syndromes and has recently been linked to Lynch syndrome in 3% of cases. We present the case of a 68-year-old male with a confirmed diagnosis of Lynch syndrome secondary to a germline MSH2 mismatch-repair gene-mutation who presented with 2 months history of non-specific abdominal pain. After imaging work-up, the patient was found to have a right upper quadrant, retroperitoneal mass. Biochemical tests were without any evidence of a hormonally active process. Fine needle aspiration of the mass revealed a poorly differentiated carcinoma of unknown etiology. The lesion was resected and found to be consistent with ectopic ACC with an associated MSH2 mutation.     

Literature statistics do not support a growth stimulating role for female sex steroid hormones in haemangiomas and meningiomas

Summary A literature review of pregnancy-related vertebral haemangiomas, pregnancy-related haemangiomas outside the nervous system and its coverings, and pregnancy-related meningiomas was performed. All three conditions tended to occur during the first pregnancy, the second or third trimester, to ameliorate postpartum, and to recur during a subsequent pregnancy. These results suggested a hormonal influence on the clinical expression of haemangiomas and meningiomas. To test whether a hormonal factor is also operative in the (not pregnancy related) symptomatic and asymptomatic counterparts of these conditions we also reviewed the literature concerning the symptomatic and asymptomatic haemangiomas and meningiomas for the following: frequency, sex and age distribution. No arguments were found to suggest that steroid hormones are strong factors in the development of asymptomatic and symptomatic lesions. The pregnancy-related counterparts have to be considered as subsets with their own behaviour.
