Photo-onycholysis caused by doxycycline has rarely been reported in children. We present the case of a boy who loved to play pinball while at the beach, holding tightly to the machine. He developed a photo-onycholysis predominantly on his thumbs while he was being treated with 20 mg/day of doxycycline, a low dose but enough to trigger the photoreaction.
