Giant ovarian leiomyoma associated with ascites and polymyositis.

Abstract

Primary ovarian leiomyoma is rare. Most cases are asymptomatic; this benign neoplasm is usually found incidentally on routine pelvic examination, at surgery, or at autopsy. We present what we believe to be the first case of ovarian leiomyoma associated with ascites and polymyositis, both of which resolved after oophorectomy. This case emphasizes the important fact that preoperative evaluation may be inaccurate. Excision of a pelvic mass with histologic evaluation remains the only reliable way to establish a diagnosis.
