[Testicular plasmocytoma: a case report]

Extramedullary plasmocytoma is rare, with less than 50 reported cases and only 8 cases of primary testicular plasmocytoma. Report of a new case. This report concerns a 65 years old patient presenting an enlargement of the testis. The diagnosis of testicular plasmocytoma was made on histological examination. There was no evidence of bone marrow involvement or systemic signs of myeloma. This case will be studied with a review of the literature

[Carcinosarcoma of the urinary bladder. Report of three cases]

Carcinosarcoma of the urinary bladder is a very rare neoplasm accounting for less than 0, 05%of urothelial tumours is a biphasic malignant neoplasm with only 79 cases reported in the English literature. Histologicaly, it exhibits morphologic and/or immunohitochemical evidence of epithelial and mesenchymal differenciation with the presence or absence of heterologous elements. It usually involves aged adults after 60 years and it has a poor prognosis. We report three cases with an emphasis on unusual histologic features. Three male patients age 76 to 86 years were found to have polypoide masses in the urinary bladder. In all cases, microscopic examination revealed biphasic neoplasms with distinct mesenchymal and epithelial components. The two first cases were remarkable respectively by the presence of chondrosarcomasrcomatous and osteosracomatous components

[Testicular lymphoma: report of 4 cases]

Background: Primary testicular lymphoma is the most common testicular malignancy in the elderly, account for 1% of all non Hodgkin lymphoma [NHL]

The aim was to report from new cases of testicular lymphoma

Cases: We report the only four cases of testicular lymphoma observed in a period of 15 years; all these cases were primary diffuse large cell B NHL. Disease course is usually aggressive, with widespread organ involvement. Retrospective analyses show a poor prognosis for this presentation

[Rectal carcinoid tumor - a case report]

Rectal carcinoid tumor is uncommon. It represent 13 percent of gastrointestinal carcinoid tumors. We report the case of a 37-year-old woman presenting with rectal bleeding. Digital examination revealed a hard mass in the rectum, 7 cm from the anal verge. Laboratory investigation was normal. Rectoscopy demonstrated a polypoid mass, 10 mm in diameter in the rectum, 7 cm from anal verge. Endoscopic resection was performed. Histology of the polyp with immunohistochemestry led to a diagnosis of carcinoid tumor. Local remnant was found. No distant metastases were found. Additional transanal excision was necessary. Clinical characteristics, histologic aspects and treatment options of rectal carcinoid tumor will be reviewed

Gastric stromal tumors, a retrospective - a study. About 19 cases

The purpose of this study is to define the therapeutic attitude to be adopted in front of a gastric stromal tumor, to estimate the results and to define the prognostic factors of these rare tumors. We report a retrospective study about 19 cases of gastric stromal tumors reported over a period of 12 years going from January, 1993 till December, 2004. All the patients were operated. Diagnosis was established by the histological and immunohistological study of gastric resection or biopsies. It was about 8 men and 11 women of whom the average age was of 62 years. The symptomatology was dominated by abdominal pain [63% of cases] and digestive bleeding [52% of cases]. A palpable mass was found in 16%of cases. The tumor location was antrum in 13 cases, fundus in 5 cases and under cardial in 1 case. A synchronous gastric and small intestinal locations was found in 1 case. The average tumoral size was 8.2cm ranging from 1.7 to 30cm. The tumor resection was achieved in 18 cases [95%]. It was widened to the adjacent organs in 1 case. Morbidity raised 5.2% and there was no operating death. At pathological examination the tumor was of weak rank of wickedness in 8 cases, high rank in 8 cases and in vague potential in 3 cases. The average follow-up was of 27 months [2 to 96 months]. During the postoperative follow-up, 3 cases of recurrence were diagnosed. The 2-year -overall survival was 83%. The prognostic factors influencing the overall survival were the high cellular density [p=0.01], local recurrence event [p=0.03] and high degree of malignancy [p=0.0002]. The treatment of gastric stromal tumors is surgical. Gastrectomy and wedge resections passing in macroscopically normal tissue are the mainstay of the treatment. Enucleating resection should be avoided. The lymph node dissection is not recommended. The new chemotherapeutic agents [the tyrosine kinase inhibitors] seem promising and could modify the current therapeutic attitude in the future

[Neuroendocrine tumours of the pancreas - a report of two cases]

Neuro-endocrine tumors of the pancreas are rare. Tumors can be discovered according to the endocrine syndrome produced. They are characterised by a slow evolution. Criteria of malignancy are metastasis to lymph node, liver or dissemination to other organs. Occurrence of multiple neuro-endocrine tumors may be seen forming multiple endocrine neoplasie type 1 or MEN-1
