Leiomyoblastoma of the stomach

Abstract

Seven cases of gastric leiomyoblastoma are reported, all of them benign. The subject of gastric leiomyoblastoma is reviewed from both clinical and pathologic aspects based on a review of 307 cases in the literature. Hemorrhage is a frequent sign (51.8%) but in 21.2% of cases leiomyoblastoma is asymptomatic. While such tumors have a malignant potential, a benign course was pursued in most of the cases (79.5%). The radiologic features of these tumors are similar to those of leiomyomas. An intramural location is the most common finding (41.4%) but intraluminal (22.7%), subserosal (25.7%) or dumbbell growth are also seen. In 31.3% of cases, the tumor is ulcerated.
