The occurrence of cctopic decidua has been observed rnost often in the ovaries, uterus, and cervix. A peritoneal localization is less frequent and usually an asymptomatic incidental finding. Ectopic decidua was investigated in biopsies taken during cesarean sections, electíve tubal ligations, appendectomy and in tubal pregnancies. ITistologic studies have been carried out of fragments from the epiploon, appendiceal serosa, tubal serosa, retroperitoneal lymph nodes and various abdominal organs. Our purpose is to report a case of peritoneal deciduosis in a 46-year-o1d woman, asymptomatic, discovered during cesarean section and rniniicking metastatic nodules (in- cidental linding). The histopathological diag- nosis was done based on specimen studied with the common technique of paraffin embcdding and hematoxilin - eosin staining. Wc believe that this decidual transformation of the peritoneurn arises from a pro gesterone-induced metaplasia of the coelomic stroma, being often a totally reversible phenomenon.
