Synchronous early gastric cancer resembling submucosal tumor at the fundus.

Concern about detecting gastric carcinoma in its early stages has increased the incidence of detecting multiple synchronous gastric carcinomas. Although gastric carcinomas may present with various gross features, those showing the features of submucosal tumor (SMT) are rare. We report on a case of synchronous gastric carcinomas comprising one lesion with typical features of superficial early gastric carcinoma and the other with atypical features that mimicked SMT. Even though synchronous gastric carcinoma is rare, it may be worthwhile to make a pathological diagnosis of coexisting SMT using endoscopic-ultrasound-guided fine-needle aspiration or endoscopic mucosal resection.
