Abstract

Graular cell tumor is a rare benign lesion of unknown histogenensis.

A 51-year-old female had a 1.0cm sized, asymptomatic, firm nodule with erythematous, shiny, and smooth surface on her right side of posterior neck for 1 year. Excisional biopsy was done under the impression of epidermal cyst. The histologic specimen showed irregularly arranged dermal nests of large polyhedral cells containing small nuclei and coarsely granular eosinophilic granules within the pale cytoplasm. The granules were PAS-positive and diastase-resistant.

Recurrence was not found until 1 year after excisional treatment.
