Abstract

Actinic prurigo is a rare and acquired idiopathic photodermatosis. It usually shows childhood onset and female predominance. Here, we present an unusual case of a male patient with coexistence of adult-onset actinic prurigo and shampoo-induced allergic contact dermatitis. He was initially diagnosed with actinic prurigo. However, after detailed examination of the distribution of the rash, careful collection of his history, and interpretation of the results of histopathologic analysis, photo test, patch test, and photopatch test, coexistence of adult-onset actinic prurigo and shampoo-induced allergic contact dermatitis associated with cocamidopropyl betaine was diagnosed. The rash improved after appropriate use of sunscreen and avoidance of shampoo containing this allergen. Dermatologists should be aware of the possibility of concurrent photodermatitis and contact dermatitis.
