Acute bleeding from leiomyoblastoma of the greater omentum. A case report

Abstract

Extragastric leiomyoblastomas are extremely rare. This is the sixth reported case of leiomyoblastoma of the greater omentum, and the only one with acute major bleeding which required an emergency operation. Leiomyoblastomas are low-grade malignant tumors, and especially the gastric ones have an excellent prognosis after surgical removal. Extragastric leiomyoblastomas have a higher rate of dissemination. However, none of the previously reported omental leiomyoblastomas showed signs of metastatic spread at the time of operation. The present patient is alive and well 18 months post-operatively.
