Pilomatrix Carcinoma: A 10 year review of the literature

Pilomatrixoma, also known as calcifying epithelioma of Malherbe, is a superficial benign skin tumour arising from hair follicle matrix cells (1,2) usually located in the head or neck region (1). It was first described in 1880 by Malherbe and Chenantais as a calcified epithelioma of sebaceous origin. In 1961, Forbis and Helwig proposed the term pilomatrixoma after establishing that the lesion actually originated from the outer root sheath cell of hair follicles (3–5).
