Pilomatrixoma – http://id.who.int/icd/entity/378820295

A benign adnexal neoplasm arising from hair-bearing skin surfaces, usually the head and neck and upper extremities. It usually presents as a solitary, slow-growing nodular mass. Morphologically, it displays differentiation towards the matrix and inner sheath of the normal hair follicle and the hair cortex. Complete surgical excision is usually curative. Occasionally, it may recur.
