Obstructive endometriosis of the sigmoid colon with fistulation into ovarian teratoma
A 44-year-old woman presented to the colorectal surgeons with a six month history of tenesmus and change in bowel habit. Initial investigations suggested a malignant colorectal tumour but biopsies showed squamous metaplasia and no colonic tissue. After further investigation and discussion at multiple multidisciplinary meetings, surgical resection of a large pelvic mass including sigmoid colon, uterus and ovary was performed. Histological examination of this mass showed intra-colonic polypoid endometriosis with fistulation through into an adjacent large cystic space, which was found to be a mature cystic teratoma.
