Bullous pilomatricoma overlying a Bacillus Calmette–Guérin scar: A rare presentation

Abstract

Pilomatricoma is a benign hamartoma of hair matrix and the most commonly occurring hair follicle tumor. It classically presents as skin colored to erythematous, smooth, deep-seated nodule of firm consistency. Rarely, a bullous presentation of a pilomatricoma has also been reported. Herein, we illustrate a case of bullous pilomatricoma occurring over the Bacillus Calmette–Guérin scar site.
