A case of leiomyoblastoma of the greater omentum, occurring in a 36-year-old man was described. Leiomyoblastoma of the omentum is extremely rare and only 6 cases have been reported in the Japanese and English literature up to date. According to the review of these cases, including the present case, 1) females were affected more frequently than males, and the age ranged from 36 to 76 years; 2) leiomyoblastoma was usually a large tumor which caused abdominal fullness and pain, and occasionally complicated with anemia and bloody ascites; 3) mitosis was rare, and there was no sign of metastasis and recurrence. Finally the morphological criteria and clinical parameters of malignancy in leiomyoblastoma were discussed.
