Hair epithelioma

Hair epithelioma is also called cystic adenoid epithelioma, multiple benign cystic epithelioma, and multiple papular hair epithelioma. This tumor line originates from benign tumors of the hair. The cases of multiple hair styles are related to heredity, most of which are autosomal dominant, but no family history of those with single hair style. Traditionally, cystic adenoid epithelioma refers to multiple lesions, while hair epithelioma can refer to single and multiple lesions. It is generally believed that such tumors originate from pluripotent basal cells and have a tendency to differentiate into hair.
