Abstract

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.

Introduction

Granular cell tumor (GCT) is an uncommon, primarily benign lesion that was first described in 1926 by Abrikossoff, who called it myoblastoma.1 This tumor is more common among blacks than members of any other race (63% of cases), and it is twice as common in women as in men.2 GCT occurs in all age groups, but it is most prevalent during the fourth and fifth decades of life.3,4
