Metastasizing Leiomyoma of the Uterus

Abstract

This report describes a patient who underwent a subtotal hysterectomy 6 years ago for fibroids. She re-presented recently with lung metastases and a pelvic mass. Macroscopic appearances at laparotomy suggested a leiomyosarcoma of the uterine stump, but histological appearances suggested the patient was suffering from the rare condition 'metastasizing leiomyoma'. Subsequent response to hormone manipulation supported the latter diagnosis.
