Warty dyskeratoma (WD) is a rare epidermal tumor that frequently arises as a papule or nodule on the head or neck of middle-aged or older persons. Histologically, it shows a cup-shaped keratin-filled invagination of an acanthotic epidermis, suprabasilar clefting with villi projecting into the clefts and acantholytic dyskeratotic cells are also present. The changes almost always involve a single hair follicle. We describe a distinctive case of WD that showed involvement of two adjoining follicles within a solitary lesion.
