Drug-induced lichenoid photodermatitis generally appears as a dermatitis, mainly on sun-exposed sites. Once recognised, photoallergic and phototoxic drug eruptions are managed by stopping the offending drug and implementing sun protection measures. Topical corticosteroids are also used, mainly for photoallergic reactions.
A 78-year-old man presented with a 12-month history of a dermatitis-like rash. It had gradually worsened and was eventually severe, particularly on sun-exposed areas of his face, neck, upper trunk, arms, forearms and dorsal hands and fingers. The rash was quite itchy and he felt it became worse after sun exposure.
