Description

Granular cell tumor (GCT) is a rare benign tumor first reported by Abrikossoff in 1926. GCT is of neural crest cell origin, and consists of a single, well-circumscribed nodule, usually arising in the tongue. We report a case of GCT arising in the tip of the tongue of a 33-year-old woman. The tumor was resected along with the peripheral soft tissue under local anesthesia. Immunohistochemical studies showed reactivity for and-S100 antibody and anti-NSE antibody. At present, the postoperative course is good, with no recurrence of the tumor.
