Abstract
Granular cell tumors are uncommon and generally benign lesions that are commonly accepted to be of Schwann cell origin. These tumors occur most frequently in the skin and oral cavity and are generally asymptomatic. However, when signs and symptoms occur, they are relative to the organ or site involved. The histological features are distinct. Surgical resection is curative in almost all cases, with only rare local recurrences. We report a case of symptomatic bilateral granular cell tumors arising in the posterior mediastinum.
