title: A case of leiomyoblastoma (epithelioid leiomyosarcoma) of the greater omentum.
abstract: A 59-year-old male complained of a palpable abdominal mass which was revealed to be a primary omental tumor by means of abdominal ultrasonography, computed tomography, angiography and laparoscopy. Histological examinations of the surgically resected tumor further disclosed leiomyoblastoma with positive stainings of both vimentin and desmin, markers for mesenchymal cells and for muscle cells, respectively. He has been well for 2 years since resection, without any relapse or distant metastasis of the tumor. Leiomyoblastoma of the greater omentum is very rare, and is important to distinguish from extraluminal tumor of the abdomen.
