Two Granular Cell Tumors of the Colon with the Endosonographic Features / 대한소화기내시경학회지

ABSTRACT

Granular cell tumor is relatively uncommon, it is usually benign and it can be located anywhere throughout the body. It is uncommon in the digestive tract, and especially in the colon and rectum. The endosonographic features of granular cell tumor are usually a relatively hypoechoic, heterogenous lesion in the submucosa, but this tumor has rarely been reported in the colon. We report here on two cases of granular cell tumors of the colon that were observed by using endoscopic ultrasonograpy for making the differential diagnosis of a submucosal tumor and these tumors were confirmed by microscopic examinations after endoscopic mucosal resection.
