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.
