Adenocarcinoma colónico originado en adenoma túbulo velloso asociado a endometriosis intestinal. A propósito de un caso.

A white, 56-years-old female patient, with a history of infertility caused by pelvic endometriosis and low digestive bleeding when defecating was attended. We made a rectosigmoidioscopy and found a tumoral hairy lesion of around 3 cm. A resection was made and a biopsy, resulting a tubule-hairy adenoma with a well-differentiated adenocarcinoma areas. We repeated the colonoscopy and biopsy of this area, showing adenocarcinoma as a result. We decided the surgical intervention making a rectosigmoidectomy by video laparoscopy. The biopsy showed neither tumor nor endometriosis at the recto sigmoid wall. We present the case in an illustrative way and reviewed the existent literature.
