| [ Summary ] | Most esophageal submucosal tumors (SMTs) are benign and of the protruding type. There are few cases that recognize subjective symptoms and there are often found by endoscopic examinations. In general, small esophageal SMT has many progress observation cases, but there is no consensus. In some cases, differential diagnosis is easy owing to characteristic morphology and color tone in endoscopic findings. The most frequently occurring type of esophageal SMT is leiomyoma. However, it is difficult to distinguish between leiomyoma and esophageal gastrointestinal stromal tumors (GISTs) with the possibility of malignancy from endoscopic findings. Therefore, biopsy is absolutely necessary for definite diagnosis. If the tumor is diagnosed as GIST, the patient is indicated for surgery. Epithelial tumors also have some submucosal tumor-like morphological characteristics. Many of them are malignant tumors and definitive diagnosis is followed by treatment according to each disease. |
