Treatment of granular cell tumor of the esophagus by endoscopic injection of dehydrated alcohol.

Granular cell tumor of the esophagus (GCTE) is a rare and mostly benign neoplasm. Its etiology is unknown and its histogenesis is uncertain. It is usually an incidental finding, detected during esophagogastroduodenoscopy. In symptomatic cases, or when the lesions are more than 1 cm in diameter, the treatment of choice has been local resection. Asymptomatic patients or tumors smaller than 1 cm are followed endoscopically. We describe a case of GCTE successfully treated by endoscopic injection of dehydrated ethyl alcohol. To our knowledge, it is the first time that such a tumor was treated by this accessible and low-cost technique.
