[Epithelioid schwannoma of the colon. Report of two cases].

Schwannomas of the colon are rare tumors. Most of them are spindle cell tumors. The epithelioid variant is exceedingly rare with only 10 cases reported in the literature.

[Pancreatic metastasis of a renal adenocarcinoma. Apropos of 2 cases].

The pancreas is an uncommon site of metastasis for renal cell carcinoma. We report 2 cases of patients who underwent total and subtotal pancreatectomy 13 and 10 years after resection of the primary tumor. One of the patients already had liver and cerebellum metastasis, the second one had a solitary metastasis to the pancreas.

[Stromal tumors in the digestive tract. A case of duodenal localization].

Background: Stromal tumors of the digestive tract are undifferentiated connective tissue tumors which are difficult to characterize even with immunohistochemistry.

Case Report: A stromal tumor of the duodenum (the most frequently encountered location) was resected entirely. Histochemistry was unable to provide a precise identification of the histological nature.
