A 50-year-old man presenting with rash after exposure to sunlight.

Photodermatoses is a condition characterized by development of a skin rash following exposure to sunlight. Here we present the case of a patient who presented with pigmented, pruritic, blistering rash that developed shortly after exposure to sunlight. Careful history revealed that the patient was on suppressive therapy with doxycycline for osteomyelitis. Following stopping of doxycycline, and symptomatic treatment, the patient had significant improvement in symptoms. The case illustrates that clinicians should be cognizant of drug induced photodermatoses particularly in individuals exposed to high doses of ultraviolet radiation.
