Definition: Acanthomas are benign tumors of epidermal keratinocytes
The proliferating cells may show normal epidermoid keratinization or a wide range of aberrant keratinization, including epidermolytic hyperkeratosis (epidermolytic acanthoma), dyskeratosis with acantholysis (warty dyskeratoma), or acantholysis alone (acantholytic acanthoma).
Keratoacanthomas are not usually considered in this category, although there is no logical reason for their exclusion.
