title: Granular Cell Tumors on Unusual Anatomic Locations.
abstract: Granular cell tumors (GCTs) are soft tissue tumors, which are thought to be derived from Schwann cells. Although most GCTs are reported to arise in tongue and oral cavity (30-50%), they can appear on any anatomic sites, even visceral organs. Herein, we report 5 cases of GCTs on unusual anatomic locations, such as palm, arm, thigh, finger, and vulvar area. Complete surgical excision is preferred treatment of choice to prevent recurrence. These cases emphasize that GCTs not involving oral cavity are more prevalent than expected, and the diagnosis should be histopathologically confirmed.
