Endometriosis of sigmoid colon mimicking cancer: A rare and abnormal presentation.
Abstract
Background: Endometriosis causing intestinal obstruction could be misdiagnosed as colon cancer due to similarities in clinical presentation. This is a case of endometriosis of sigmoid colon in a 37-year-old nulliparous woman who presented with intestinal obstruction that necessitated partial colectomy. Histological examination revealed endometriosis of the sigmoid colon and the report was received by both the surgeons and patient with joyous surprise. We present this case for its mimic of colon cancer clinically, rarity and abnormal presentation.
