Granular Cell Tumor on the Chest of a 9-Year-Old Female: Case Report and a Retrospective Analysis

Background Granular cell tumor is a benign tumor originating from Schwann cells. Children and adolescents are rarely affected. We report a 9-year-old female who presented with a cutaneous granular cell tumor on the chest. Objective To determine the incidence of granular cell tumor and proportion of tumors seen in the pediatric population at our center. Methods We retrospectively reviewed the surgical pathology records from 1997 to 2014 at our center. Results The incidence of granular cell tumor is five cases per million person-years (95% CI 3-8). Of the 18 cases, 9 cases occurred in the pediatric population. Conclusion Fifty percent of granular cell tumor cases diagnosed at our center occurred in the pediatric population. Granular cell tumor may not be as rare as we expect in the pediatric population.
