Endometrial stromal sarcoma of the rectosigmoid colon arising in extragonadal endometriosis and revealed by portal vein thrombosis.

Malignant transformation is an infrequent complication of endometriosis. The ovary is the primary site in 76% of cases, and extragonadal sites are identified in 24%. Endometrioid carcinoma is the most common histologic type; sarcoma is very rare. We report a case of low-grade endometrial stromal sarcoma of the rectosigmoid colon presenting with epigastric pain due to portal vein thrombosis. This tumor arose from extragonadal endometriosis in a 61-year-old woman and was treated by surgical resection. The main differential diagnosis of this unusual colonic neoplasm includes primary mesenchymal tumors, such as gastrointestinal stromal tumors.

[Mixed corticomedullary tumor].

BACKGROUND: Pheochromocytoma and primary hyperaldosteronism rarely occur simultaneously. Few cases have been reported in the literature. CASE REPORT: A patient explored for hypertension was found to have hypokalemia related to primary hyperaldosteronism. Pathology examination of the ablated adrenal showed a co-existing pheochromocytoma suspected at history taking although urine catecholamines were normal. DISCUSSION: Different pathogenic hypothesis have been proposed. Such dual tumors could be a simple coincidence, occur in a particular genetic setting, be related to direct contact between cortical and medullary tissue leading to reactional cortical hyperplasia, pheochromocytoma produced factors stimulating aldosterone synthesis, or factor X, a substance produced by cortical adenomas and favoring growth of the pheochromocytoma.

[Rare tumors of the prostate or seminal vesicles. Report of a case of leiomyosarcoma].

An unusual case of leiomyosarcoma of the prostate presented as a recurrent pelvic cystic mass. Prostatic sarcoma are rare in adults with a poor prognosis. It is often difficult to determine a definite origin. The authors reviewed the differential diagnosis with pseudosarcoma, inflammatory fibrosarcoma and others rare tumors of the prostate and the seminal vesicle.

[Cloacogenic cancers of the anal canal: a retrospective study of 17 cases].

This study involved 17 cloacogenic cancers classified on the Morson and Jass histological scale and on the TNM clinical classification as T1 (4), T2 (3), T3 (3) and T4 (7) and including 5 N+ cases at the time of diagnosis. Treatment combined radiotherapy and surgery and the overall actuarial survival was 45% after 5 years. These results confirm that the response to treatment of cloacogenic cancers is similar to that of epidermoid cancers, notably with regard to the response to radiotherapy, and that the prognosis depends above all on the initial extent of the cancer. In contrast, cancers showing little or no differentiation (small cell cloacogenic cancers) are distinguished from other duct cancers by their explosive metastatic potential.
