Neoplasms of the stomach can originate from both epithelial and subepithelial cells. These two types of tumors have different morphological characteristics according to their origin including the mucosal surface texture and contour of the mass in endoscopic examination. However, on rare occasions, neoplasms of an epithelial origin manifest the features of a submucosal tumor on a gross examination, and require additional and more invasive approaches, such as a strip biopsy, computed tomography, and endosonography, to define their nature. We encountered a case of a gastric adenocarcinoma in a 44 year-old woman, which was initially considered to be submucosal tumor by the endoscopic examination and was finally diagnosed after resecting the tumor.
