Cutaneous carcinogenic risk evaluation in 375 patients treated with narrowband-UVB phototherapy: A 15-year experience from our Institute.

Despite the small number of patients and limited follow-up, our data suggest that NB-UVB may trigger cutaneous carcinogenesis, mainly in patients at risk for NMSCs, increasing their personal risk for single and multiple neoplasms, usually superficial BCCs. MM risk does not seem to be enhanced.
