Resumo

Granular cell tumors are infrequent benign neoplasms that tend to develop in the head and neck, particular/y in the tangue. They gene rally produce no symptoms. As the clinical presentation of these tumors is nonspecific, diagnosis is mainly histopathological, with the identification of large cells containing intracytoplasmic eosinophilic granulations that lend the tumor its name. lmmunohistochemical techniques have demonstrated the positivity of these cells to vimentin, S-100 protein and neuron-specific enolase - thus confirming the neural (Schwann cell) origin of granular cell tumors. The case is described of a patient with a granular cell tumor in the retromolar trigone, a very infrequent location for such neoplasms.
