 As there are usually no symptoms associated with esophageal or gastric submucosal tumors, they are often found first by endoscopy or double-contrast radiographic examination. When a submucosal tumor is detected, it should be defined by its shape, region, size, color, solidity, surface appearance, presence of depressions, ulcers, or multiple lesions, etc. The findings of a size in excess of3cm, irregular surface, accompanied by depressions or ulcerations, and features of rapid growth represent frequently malignant manifestations of these lesions.

 The cases examined in the present study were reported as leiomyoma(81.0%), granular cell tumor, and hemangioma(approximately5%)as benign esophageal submucosal tumors, and malignant melanoma(42.8%)or leiomyosarcoma(33%)as malignant esophageal submucosal tumors. The tumors were identified as leiomyosarcoma(40.4%), aberrant pancreas(18.2%), or inflammatory fibroid polyp(IFP)(10.3%)as benign gastric submucosal tumors, and malignant lymphoma(62.3%)and leiomyosarcoma(22.4%)as malignant gastric submucosal tumors.
