| [ Summary ] | Submucosal tumors (SMT) of the stomach are observed in about 1.5% of all gastric tumors. The most frequent types of SMT are cases of malignantlymphoma. Leiomyosarcoma cases were next in frequcncy. On the other hand, almost half of SMT cases were benign. By using roentgenographic or endoscopic examination, we can sec that SMT are covered with normal gastric mucosa, with or without bridging folds and ulcerations. By using endoscopic ultrasonography (EUS) these lesions are diagnosed more exactly than through roentgenography or endoscopy, because continuations of the normal gastric layer structure, the inner echo level and the margin of tumors are easily obtained as sectional images. Angiography, abdominal ultrasonography and computed tomography are supplementarily applied to diagnose SMT. | |
