Pediatric Papular Mycosis Fungoides Treated With Phototherapy: A Case Series

Papular mycosis fungoides (PMF) is a rare clinical variant with limited data on long-term outcomes, particularly in children. Our study describes sociodemographic, clinical, therapeutic, and follow-up data in 5 pediatric patients with PMF, all treated with phototherapy (PUVA, PUVAsol or narrowband UVB). Complete remission was achieved by 60% within a median of 6 months (IQR 4.5-7.5 months), and the median follow-up was 19 months (IQR 6-27 months), with no disease progression and 100% overall survival. These findings suggest that papular MF follows a favorable course, similar to early-stage MF or other clinical variants with a positive prognosis.
