Pilomatricoma

definition

A tumour composed of cells resembling those of the hair matrix, which undergo 'mummification' and may calcify. It may occur at any age from infancy, the majority of the patients being under 20. Females are affected more often than males. The lesion presents as a solitary, deep dermal or subcutaneous tumour 3-30 mm in diameter, situated on the face, neck, or upper extremities. The overlying skin may be normal or slightly discoloured with a reddish-blue tint, and the lesion has a firm to stony-hard consistency.
