© 2013 Hainan Medical College.Benign cystic peritoneal mesothelioma also known as peritoneal inclusion cyst is a rare lesion that usually occurs in women of reproductive age. Giant peritoneal inclusion cysts are extremely rare and to the best of our knowledge only has been reported in man to date. Hereby, a case of a 45-year-old multiparous patient with a giant peritoneal inclusion cyst that mimicks an ovarian cyst is presented. The patient with a complaint of abdominal distention sought out to our outpatient clinic. In her medical history she has had neither prior surgery nor pelvic infection. Physical examination revealed a giant smooth surfaced pelvic mass originating from the left adnexal space. Ultrasonography and computed tomography images supported the pelvic examination. The patient underwent diagnostic laparatomy and frozen section analysis. Histopathological diagnosis revealed a peritoneal inclusion cyst with endometriotic focus. After one year from surgery, the patient has had no recurrences. Although giant masses of pre-menopausal women are usually malignant, clinicians may encounter with rare benign tumors such as peritoneal inclusion cysts and should be aware of them in the differential diagnosis.
