Sclerosing peritonitis occurring in association with juvenile granulosa cell tumour - a cause of concern

Sclerosing Peritonitis (SP) is characterized by fibrous thickening and adhesions of the peritoneum and it is encountered frequently in association with peritoneal dialysis, practolol and anticonvulsant therapy. Rarely does it present as a gynaecological complication, most commonly in conjunction with luteinized thecoma of ovary. Very rarely has sclerosing peritonitis been reported to occur with ovarian cystic teratoma and a luteinized variant of adult granulosa cell tumour, among which only one case has been reported in the English literature. An 18-year-female presented with a history of lower abdominal pain, of one month's duration. At surgery, an ovarian mass was noted, along with adhesion of bowel loops which were enclosed within a diffusely thickened peritoneal membrane, forming a cocoon. Adhesions were seen in bilateral paracolic gutter and infracolic omentum, which were suggestive of metastatic deposits. Histopathology of ovarian lesion was interpreted as a juvenile granulosa cell tumour. The peritoneal process revealed sclerosing peritonitis. We emphasize this rare association of sclerosing peritonitis with juvenile granulosa cell tumour and that the peritoneal process of sclerosing peritonitis in a juvenile granulosa cell tumour should not lead to over staging of an ovarian tumour.
