[Granular cell tumor of the esophagus]

Abstract

We report a new case of granular cell tumor (GCT) is a benign neoplasm in the esophagus (a rare location of which there are only described 80 cases. The tumor was diagnosed in a man aged 55 by endoscopy (asymptomatic from the esophagus point of view) during a chronic liver disease survey. The biopsies of the 3 cm polyp suggested a GCT. The patient died and the necropsy confirmed the presence of a submucous tumor with polygonal cells, wide cytoplasm, eosinophil, granular and ovoid nucleus. The cytoplasm granules were positive PAS and a resistant diastase, without signs of malignancy. In our case, the endoscopy resection was not possible because the state of the patient, although it is the most reasonable therapeutic choice in the most cases.
