Solitary Oral Epidermolytic Acanthoma: Case report of a rarely diagnosed entity

Epidermolytic acanthoma (EA) represents a rare localized form of epidermolytic hyperkeratosis (EHK) clinically resembling warty lesions and showing a strong predilection for the genital skin of males. Herein, we present a case of oral solitary EA affecting a 71-year-old Caucasian man. Clinically, the lesion was white, well-circumscribed and sessile, measuring 2 mm in diameter and located on the posterior mandibular buccal gingiva. An excisional biopsy revealed, microscopically, pronounced hyperkeratosis and acanthosis with formation of keratin crypts.
