초록
A 49-year-old woman was referred to our hospital for further treatment due to the suspicion of a submucosal tumor in a routinescreening colonoscopy. On colonoscopy, a 1-cm sized subepithelial mass with normal overlying mucosa in the hepatic flexure wasfound. Endoscopic ultrasonography (EUS) showed a homogenous hypoechoic lesion arising from the second and third layer. Wewere unable to make a final diagnosis because the lesion showed a small tumor with atypical macroscopic morphology including EUSfindings. Therefore, endoscopic submucosal dissection was performed for the diagnostic treatment of the tumor. Submucosal dissectionwas performed just above the muscle layer, and the tumor was removed completely and reliably without any acute complications suchas perforation. Based on histopathological findings, we diagnosed a benign, calcifying fibrous tumor (CFT). The present case is the firstreport of successful endoscopic diagnosis and treatment of colonic CFT mimicking a submucosal tumor.
