A Case of Granular Cell Tumor / 대한피부과학회지

ABSTRACT

We report a case of granular cell tumor in a 62-year- old female. She had a 1. 5 cm sized, asymptomatic, firm nodule with central depression on the lateral aspect cf the left orbit. Histologically, the dermis had many large, pale tumor cells arranged in clusters and strands. The cells had a distinct cellular membrane and a pale cytoplasm filled with faintly eosiinophilic,coarse granules. The characteristic faint granules within the tumor cells are PAS-positive and diastase-resistant. The overlying epidermiis showed pseudocarcinomatous hyperplasia. We treated it with total excision.
