Abstract

In 1960 Martin and his associates described another type of tumor of the stomach derived from the smooth muscle, which they named myoid tumor in a study of six patients. In 1962 Stout applied the term "lelomyoblastoma" to this interesting entity in a report of a collected series of 69 patients. Tumor cells are round or polygonal epithelioid cells, which contain perinuclear vacuole or clear zone. A 58 year-old female was admitted to this hospital because of epigastric discomfort for three months. At Upper gastrointestinal series and gastrofiberscope, a round hemispherical submucosal tumor was noted at posterior wall near the lesser curvature of gastric antrum. After subtotal gastrectomy, the submucosal tumor was diagnosed as leiomyoblastoma. Because leiomyoblastoma are rare and easily misdiagnosed as leiomyoma or leiomyosarcoma, careful histologic study is recommended.
