Granular cell tumor of the tongue: Report of a case.

Granular cell tumor (GCT) is a benign lesion characterized by the accumulation of plump cells with abundant granular cytoplasm. The formation of a granular cell tumor is a neoplastic process and the lesions formed are of neural derivation, as supported by immunophenotypic and ultra structural evidence. This type of tumor has been found to be both benign and malignant although malignancy is rare and comprises only 2% of all granular cell tumors. Here we report a case of GCT in a 40 year old male patient on the posterolateral border of tongue.
