title: [A boy with nail abnormalities].
abstract: A 12-year-old boy consulted the dermatologist for nail abnormalities. Three weeks earlier, he was treated with doxycycline 100 mg BID for 10 days because of erythema chronicum migrans. Following sun exposure, the patient had developed distal onycholysis surrounded by a hyperpigmented zone. He was diagnosed with doxycycline-induced photo-onycholysis.
