Sclerosing peritonitis in a case of benign cystic ovarian teratoma - A case report

A 52-year old woman with regular menstruation presented with ascites and abdominal swelling and pain. Bilateral salpingo-oophorectomy, hysterectomy and excision of a few peritoneal nodules was performed. The omentum was firm, giving the impression of carcinoma. The ovaries were enlarged, each containing a non-ruptured cyst with thick yellowish fluid. Microscopy revealed a sclerosing peritonitis in the omentum and nodules. There was a benign cystic teratoma in the left ovary, a corpus luteum in the right ovary. Follow-up has been uneventful for 26 months. The sclerosing peritonitis is considered to be secondary to the ovarian changes, most probably the teratoma.
