A 44-year-old man was found to have an abnormality in the gastric antrum on mass examination for adult diseases in September 1991. The patient visited to our department for the more detailed examination on November 1, and was admitted on November 28. Examination by x-ray and endoscopic examination revealed a submucosal tumor of approximately 3cm in size. The surface of the tumor was slightly uneven and was associated with a bridging fold. Endoscopic ultrasonography revealed that the tumor extended from the submucosal layer to the proper muscle layer, and appeared to be continuous with the proper muscle layer. The inside of the tumor was almost homogeneous and showed a slightly higher echoic level than the proper muscle layer, resembling the findings of leiomyoma. The patient underwent partial resection of the tumor at the department of surgery of our hospital on January 10. The specimen was 32×22×18mm in size, and histological examination revealed that the tumor was a glomus tumor in the submucosal and proper muscle layers.
