 This is a report of granular cell myoblastoma with concomitant neurinoma found and confirmed in the same stomach. Some comments thereon are added.

 The patient is a 62 years old female, complaining of pain in the epigastrium and loss of appetite. Physical examination revealed no abnormality, except slight anemia. At X-ray examination, irregularity of mucosal relief was observed in the gastric body, while endoscopically, round, pea-sized protrusion was seen in the same region, suggestive of a solitary, broad-based polyp. Operation was accordingly done by B Ⅱ method. A tumor was found in the resected specimen, measuring 10 by 11 mm, in the submucosa on the anterior wall of the gastric corpus. Histologically this proved to be granular cell myoblastorna. There was also found a smaller tumor in the greater curvature side of the corpus. It was confirmed as neurinoma pathohistologically.

 Predilection site of granular cell myoblastoma is chiefly in the tongue, and it is elsewhere seen in such parts as the skin, subcutaneous layer, larynx, muscle, respiratory organ and the genitourinary system. Its existence in the stomach has been up to now reported only in one instance by Stout. This tumor is generally considered as neoplastic proliferation of degenerated periphery nerve.

 The case reported in this article refers to two co-existent tumors of neurogenous origin, each of different histological etiology.
