Desmoplastic Melanoma Arising after 1,064 nm q-Switched Nd:YAG Laser of a Suspected Solar Lentigo.

ABSTRACT

OBJECTIVES: To present a case of desmoplastic melanoma (DM) arising after laser therapy of a suspected solar lentigo with the 1,064 nm Q-switched (QS) NeodymiumYttrium-Aluminum-Garnet (NdYAG) laser and discuss the safety of treating suspected solar lentigines with laser therapy. METHODS: Case presentation with discussion. RESULTS: We describe a patient who developed DM after 1,064 nm QS NdYAG laser therapy to a suspected solar lentigo. CONCLUSIONS: Limited generalizable studies regarding the safety of laser therapy for solar lentigines exist, specifically for the 1,064 nm QS NdYAG laser. Therefore, we recommend caution is taken when considering laser therapy for these lesions, as well as strong consideration for histologic confirmation prior to therapy.
