Introduction

Pilomatrixoma was first reported in 1880 by Malherbe and Chenantais . They described a calcifying epithelioma , believing it to be a sebaceous gland tumor . Since 1905, this uncommon neoplasia has been called Malherbe’s calcifying epithe­lioma . Numerous studies suggest that this tumor stems from the external sheath of hair follicles. In 1961, Forbis and Helwig  proposed the term pilomatrixoma to avoid a connotation of malignancy. It is a benign skin neoplasia, originating from hair follicle matrix cells, representing 0.12% of skin tumours. Pilomatrixoma most commonly occurs in the head and neck. These  are frequently misdiagnosed or missed from the differential diagnosis or both.
