A 43-year-old man with the chief complaint of epigastralgia was diagnosed as having a submucosal tumor of the stomach. Distal gastrectomy and lymph nodes dissection (R2) were performed. The tumor was located in the greater curvature from the body to the antrum of the stomach, and showed intra and extraluminal growth, measuring 15.0 ± 8.5 ± 5.5 cm with ulceration. The specimen had a huge foci of hemorrhage and necrosis, presenting as a cyst contained dark red fluid, 760 ml in volume. The patient has been well for 3 years and 10 months after operation. In addition to 143 cases of leiomyoblastoma of the stomach reviewed by Ono and the coworkers in 1982, 124 cases thereafter were collected and allocated to group A (26 cases accompanying by hemorrhagic and necrotic foci) and group B (98 cases without them). Group A included 4 cases of the intraperitoneal hemorrhage. There was no statistical difference between two groups in the distribution of age, sex and location, but there was in the growth form and size of tumors (p<0.005). In short, an increase in size of tumors presenting as extraluminal growth increase the frequency of association of hemorrhagic and necrotic foci.
