Malherbe's calcifying epithelioma -->
medical dictionary

A tumour composed of cells resembling those of the hair matrix, which undergo 'mummification' and may calcify. It is a relatively uncommon tumour, which may occur at any age from infancy. The majority of patients are under 20, and females are affected more than males. The lesion is usually a solitary deep dermal or subcutaneous tumour 3-30 mm in diameter, situated in the head, neck, or upper extremity.
