[Primary descending colon lymphoma: case communication].

Primary colon lymphomas are very uncommon gastrointestinal tumors, more so in the descending colon. We would like to present this clinical entity with the case of a 33-year-old woman in order to inform them about the case of Primary colon lymphoma that was encountered and to review the literature. In her case, the diagnosis was suspected from the clinical symptoms, images and fiber endoscopy study. The diagnosis was confirmed by anatomopathology and inmunohistoquimic study. The woman was subjected to exploratory laparotomy and the final diagnosis was given to be high-grade MALT type Lymphoma B cells (Non-Hodgkins Lymphoma Big Cell) big cells) EII2.
