CASTANO LLANO, Rodrigo et al. Tumor de células granulares en el tracto gastrointestinal. Rev Col Gastroenterol [online]. 2005, vol.20, n.2, pp.79-85. ISSN 0120-9957.

Granular cells tumors are ubiquitous lesions in the gastrointestinal tract, are rare and asymptomatic and they are generally an incidental discovery at gastroduodenoscopy or colonoscopy. In the gastrointestinal tract they are more frequently located in the esophagus, right colon and rectum, stomach, appendix, small intestine or biliopancreatic tract. This article describes three patients with four tumors of granular cells in rectum, esophagus (2 lesions) and appendix. It becomes special emphasis in their neural origin, their benign behavior that justifies the endoscopic resections or limited surgical excisions and the necessity of a pursuit for the possibility, although little, of malignant transformation.

Keywords : Rectal polyp; submucosal polyp; granular cell tumor; appendix tumor; esophageal tumor.
