Benign neoplasms of the stomach are uncommon in children. They include adenomatous and hyperplastic polpys, leiomyomas, lipomas, and other lesions. Gastric leiomyoma in childhood represent only 1% of all gastrointestinal neoplasms reported, and slightly more than half of these are gastric. The tumor arises in the muscle layer of the stomach and is usually intragastric and submucosal. Barium contrast studies are useful in localizing leiomyoma with significant intramural or submucosal growth. An endoscopy can permit histologic confirmation if the tumor has eroded through the mucosa. Differentiation however, of malignant lesions from benign submucosal leiomyomas may be difficult. Using endoscopic ultrasonund imaging, highly accurate gastrointestinal tumor characterization, especially submucosal masses, and differentiation of malignant from benign lesion are now relatively possible without surgery. We experienced a case of a gastric submucosal tumor regarded as a leiomyoma, which was diagnosed using endoscopic ultrasonography, and report the findings with a review of related literatures.
