[Adrenocortical oncocytic cells tumor: case report and review of literature]. / Tumeurs corticosurrénaliennes à cellules oxyphiles: à propos d'un cas et revue de la littérature.

Adrenocortical oncocytic cells tumor are rare. We report on a case. To our knowledge, 34 cases have been described to date. These tumors were asymptomatic and non-secreting. Diagnosis was made on histologic exam. Oncocytic cells were marked by the increased number of hypertrophied mitochondria. The etiology remained unknown. The prognosis was good despite the fact that three cases were considered as carcinomas and 10 others considered as tumors of uncertain malignant potential. All tumors were cured by surgery. Management and follow-up were established upon prognosis.

[Hyperplastic polyps arising in islands of gastric mucosa in the duodenum]. / Polypes hyperplasiques développés sur des îlots de muqueuse gastrique dans le duodénum.

Hyperplastic polyps originating from islands of gastric mucosa can be observed in the duodenum. We report 3 cases of duodenal hyperplastic polyps on antral or fully developed fundic mucosa. They macroscopically presented as small confluent polyps or as large villous polyps. Their microscopic features were the same as those observed in hyperplastic gastric polyps. This type of polyp must be added to the list of tumor like lesions of the duodenum that may endoscopically present as polyps.
