Two cases of granular cell tumors of the head and neck at different sites.

Granular cell tumor (GCT) is an uncommon, primarily benign lesion. We describe 2 cases of GCT. Patient 1 was a 38-year-old man who presented with a reddish, vegetative lesion that involved the posterior third of the left true vocal fold. Patient 2 was an 18-year-old girl who presented with a firm, slightly extruded submucosal mass in the posterior lateral third of the tongue. Both lesions were identified as GCTs on biopsy. Both tumors were removed surgically, and both patients exhibited no signs of recurrence during follow-up. It is important that otolaryngologists be familiar with GCT and its management. Although the length of follow-up has varied substantially in the literature, we recommend long-term surveillance, including regular clinical examinations and periodic imaging with contrast-enhanced magnetic resonance imaging, at least until additional studies have clarified the natural history and recurrence patterns of GCT with greater certainty.
