A Case of Benign Retroperitoneal Schwannoma of the Obturator Fossa / 대한산부인과학회잡지

ABSTRACT

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.
