Since its FDA approval in 1999, photodynamic therapy (PDT) with topical 5-aminolevulinic acid has become an increasingly
popular modality for the treatment of actinic keratosis (AKs). It is hoped that in addition to improving clinical signs
and symptoms of AKs, PDT might prevent the development of skin cancer. We present a case of a patient developing a keratoacanthoma
immediately following PDT for AKs.
