[Abdominal wall endometriosis: case report].

Endometriosis is defined as the presence of endometrial glands and stroma outside uterus. This ectopic finding occur in the abdominal wall among 0,03% to 1% of women with prior gynecologic surgery, particularly after cesarean section. Most frequently, endometriosis is present as a palpable mass, painfull during menstrual period, near surgical scar. It could mimic other pathologies such as hematomas, granulomas, inicisional hernias, abscesses and tumors. We report the case of a 35 years old woman with a painful mass during menstruation nearly cesarean scar. The tumor was completely removed and a polipropylen mesh was placed to repair the abdominal wall defect. It was identified as endometriosis in the anatomo-patologic examination.
