Proliferating pilomatricoma - Case report

Abstract

Proliferating pilomatricoma is proliferative, rare tumor variant of pilomatricoma. It is a benignneoplasm of hair matrix that can have potentially involve local recurrence. We report the case of a 60-year-old man who presented an asymptomatic nodule on the scalp. Histological exam demonstrated a basaloid epithelium at the periphery, filled with eosinophilic cornified material containing shadow cells. The tumor was excised and there was no evidence of recurrence one year later.
