Extragenital endometriosis in sigmoid colon and lympathic nodule

Although endometriosis is a common disease in women of childbearing age, intestinal endometriosis is unusual and may cause clinically significant complications. We report a 43-year-old woman with extragenital endometriosis who presented with intestinal obstruction. She was operated on with a preoperative diagnosis of malignancy. The diag­nosis of endometriosis was made only after histological examination of the resected specimen. Intestinal endo­metriosis has a diverse clinical spectrum, with nonspecific features in many patients. In female patients who have unexplained digestive complaints, endometriosis should also be considered in the differential diagnosis.
