A case of cystic change of pelvic retroperitoneal Schwannoma misdiagnosed as an ovarian tumor / 대한산부인과학회잡지

Retroperitoneal Schwannoma is relatively rare and benign tumor originating from Schwann cell. Schwannomas arising in the retroperitoneum are infrequently reported. The majority of Schwannoma is found incidentally and misdiagnosed for other benign conditions both clinically and radiologically. We report a case of a benign retroperitoneal pelvic Schwannoma which was preoperatively misdiagnosed as an ovarian tumor with brief review of literatures.

A Case of Rapidly Growing Huge Granulosa Cell Tumor of the Ovary / 대한산부인과학회잡지

Ovarian granulosa cell tumor is a uncommon low-grade feminizing malignancy. Its natural history shows slow growth without pain. It often reveals to be very large sized mass when diagnosed, and is confined to the involved ovary in many cases. Complete surgical removal is primary treatment and recurrences thereafter are relatively common. Postoperative adjuvant therapy including reoperation, chemotherapy, radiation therapy or a combination therapy has been used with various degrees of success. We experienced a case of huge ovarian granulosa cell tumor occupying whole abdominal cavity by rapid growth, which is presented with a brief review of corresponding literatures.
