title: Photo-onycholysis caused by olanzapine and aripiprazole.
abstract: Photo-onycholysis associated with drugs is an uncommon disorder. We report the case of a woman who developed photo-onycholysis on multiple nails after uptake of olanzapine. Substitution of olanzapine with aripiprazole further exacerbated the problem. The possible mechanisms of photo-onycholysis development by modern atypical antipsychotics, modulating dopamine receptors, are discussed.
