Clear cell Bowen's disease (BD) is a rare histopathological subtype of BD, characterized by epidermal atypical keratinocytes with clear-cell changes exceeding 80% of the tumor population. Warty and clear cell Bowen's disease (WCCBD) is a recently described variant of clear cell BD, with verrucous and hyperkeratotic surface changes in addition to pathological features consisting of an extremely acanthotic epidermis, hyperkeratosis and clear-cell changes. Herein we present a 72-year-old man with a 1-year history of tumoral lesion located on the left cheek with a diagnosis of WCCBD, in whom we achieved excellent result with photodynamic treatment. To the best of our knowledge, this is the second reported case of this entity.
