Pilomatricoma (pilomatrixoma) or calcifying epithelioma of Malherbe, is a tumor with differentiation toward hair cells, particularly hair cortex cells. It frequently presents as a firm, deep-seated nodule that is covered by normal skin. Bullous pilomatricoma is an unusual clinical variant. Reports on bullous variant of pilomatricoma is sparse, and only 17 cases have been reported world-wide until date out of which only two cases are reported from India. We present a report of a 17-year-old female with a solitary reddish semi-transparent blister over her right upper arm since 3 months resembling a bouncy ball. Histopathology revealed tumor nests of basophilic cells and eosinophilic shadow cells, which are consistent with pilomatricoma.
