Allergic onycholysis and paronychia caused by cyanoacrylate nail glue, but not by photobonded methacrylate nails.

Artificial acrylic nails may induce side effects such as fingertip dermatitis, periungual dermatitis, onycholysis, paresthesiae, Raynaud's phenomenon, ectopic facial involvement, and allergic contact dermatitis. We present a patient who developed allergic onycholysis from a cyanoacrylate used in a nail adhesive. She was able to use photobonded sculptured nails because they contain methacrylates that do not cross-react with cyanoacrylates.
