Abstract

A rare case of abdominal pain secondary to endometriosis in a 52-year-old man with cirrhosis is presented. The patient had a repair of recurrent inguinal hernia 7 months prior to presentation. An exploratory laparotomy revealed a 4.5 cm × 2.5 cm cystic mass attached to the urinary bladder and the inguinal area. The mass pathology showed a cystic lumen of diameter of 1. 5 cm filled with old blood and surrounded by thick muscular mass. Microscopically, the lesion consisted of thick smooth muscle fibers that concentrically surround a central lumen that is bordered by endometrium such as glands and stroma. Immunostains were positive for estrogen receptors and progesterone receptors in the glandular component and for CD10 in the stroma, which is consistent with endometriosis.
