Granular cell tumors of the esophagus: a report of two cases and review of the literature.

Two patients with granular cell tumors of the esophagus are presented. Both were men, 54 and 51 years old, respectively, and without tumor-related complaints. Diagnosis was made by esophagogram and endoscopic biopsy. The two patients were treated with a left thoracotomy and local excision of the tumors. A review of the world literature was carried out and data of general interest were collected. The symptoms and management of esophageal granular cell tumors, as well as histogenesis, are discussed.
