Abstract
Granular cell tumor is a relatively uncommon benign tumor that occurs at sites such as the skin, oral cavity, breasts, and bronchus.
We report a case of multiple granular cell tumor on the lateral border of the tongue.
In November 200X, a 50-year-old woman presented to us with a nodule on the left lateral border of the tongue. It was approximately 8 mm in diameter, had distinct margins, and was hard elastic on palpation. The nodule was painful only when it came in contact with the teeth. The right lateral border of the tongue had normal mucosa. The nodule was resected under local anesthesia. The pathological diagnosis was a granular cell tumor.
Three years later, a nodule of 5 mm in diameter appeared on the right lateral border of the tongue. This lesion was also resected and the pathological diagnosis was again a granular cell tumor. No recurrence was observed at either of the surgical sites.
Granular cell tumor is usually a benign tumor. However, it shows the potential for local invasion, recurrence, and malignant transformation. Thus, such tumors should be strictly observed for malignancy and recurrence.
