title: [Duodenal reticulosarcoma (an unusual case of primary duodenal tumor)].
abstract: A rare case of primitiv mesenchimatous neoplasm of the duodenum is presented. After a review of the few cases reported in the literature, the authors emphasize the unspecificity of the clinical features and the diagnostic reliability of the fibroendoscopy. Alterations of the cellular immunity were presented in this case. The restricted posibilities of treatment in these highly malignant tumors are also discussed.
