Sigmoid Endometriosis Mimicking Carcinoma of Sigmoid Colon : A Case Report

Although intestinal endometriosis is not uncommon in women of reproductive age. Endometriosis of  colon that involved mucosa is quite rare and differential diagnosis from colon cancer may be difficult. We present a case of middle-age woman with colonic endometriosis. Her initial clinical diagnosis including radiologic and endoscopic studies was sigmoid colon cancer with right ureteric involvement. After laparotomy and en-bloc resection, the histological examination revealed extensive involvement of endometriosis. Conclusion : Colonic endometriosis is a relatively rare disease and is difficult to differentiate from  malignancy. Keywords : Colonic endometriosis, intestinal endometriosis, mimicking colon cancer
