Endometrioid adenocarcinoma of rectum, a rare site for extraovarian endometriosis associated cancer

We report a case of endometrioid adenocarcinoma arising from the wall of the rectum. A fifty five year old woman presented with painless rectal bleeding and altered bowel habit. She had previous endometriosis and had underwent total abdominal hysterectomy eight years ago. Physical examination showed no palpable masses and flexible sigmoidoscopy revealed narrowing at the rectosigmoid junction with macroscopically normal looking mucosa. Biopises of this area only showed normal tissue but a CT scan confirmed the presence of a mass within the wall of the rectum and enlarged pararectal lymph nodes suspicious of malignancy, with no evidence of distal metastases.
