Abstract

We investigated the incidence of phototoxic skin reactions in pediatric BMT recipients treated with voriconazole. Nine out of 40 patients (22.5%), all Caucasian, developed skin lesions in sun-exposed distributions. Dermatologic findings included sunburn-like erythema, pseudo-porphyria, linear papulovesicular lesions, severe erosive cheilitis, dermatoheliosis and lentigines. Patients were treated with sun avoidance, high-potency sunscreens, and topical steroids with significant improvement in all cases. Prolonged voriconazole use requires close monitoring for chronic skin toxicities. Long-term risks including the risk of skin cancer need to be investigated. Pediatr Blood Cancer 2014;61:1325-1328.
