title: Giant ovarian leiomyoma associated with ascites and polymyositis.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  Excision of a pelvic mass with histologic evaluation remains the only reliable way to establish a diagnosis.
