Forearm Granular Cell Tumor: A Rare Entity.

Granular cell tumors are uncommon benign masses. They occur rarely and are usually solitary, nontender lesions, with a tendency to occur in the head and neck region and a predilection for the tongue. A malignant variant is even less common. To date, its origin remains uncertain. We report the case of a 19-year-old Egyptian man who presented to the Kasr eini Plastic Surgery Clinic with a swelling on the posterior aspect of his right forearm. After surgical excision and histopathological examination, it was found to be a granular cell tumor. This finding was of interest because of the rarity of the neoplasm in general, but in particular because of the scarcity of its occurrence in this anatomic location and the patient's sex, and age group.
