“…The number of sessions needed to obtain CR in PLC varies between studies. Table shows the cases of adult PLC treated with NB‐UVB in the published literature . Four studies obtained CR in 87.5–92.9% of treated patients, as in our study, with the number of sessions ranging from 11 to 45 .…”

“…Patients may benefit from the use of topical corticoids, although these seem to be ineffective in changing the course of the disease. 2,4 Phototherapy is one of the first-line PLC therapies, particularly in more extensive disease. 1 Multiple reports of PUVA, broadband ultraviolet (UV)B and narrowband (NB)-UVBhave been published.…”

“…Pityriasis lichenoides chronica (PLC) is an uncommon dermatosis of unknown aetiology . The classification and treatment of PLC is challenging, and some authors consider that pityriasis lichenoides et varioliformis acuta (PLEVA) and PLC are different severities of the same disease . PLC may last several weeks.…”

Treatment of adult diffuse pityriasis lichenoides chronica with narrowband ultraviolet B: experience and literature review

et al. 2017

Pityriasis lichenoides chronica (PLC) is an infrequent dermatosis of unknown aetiology, wholse evolution and response to treatment differs between children and adults. When PLC is recalcitrant or unresponsive to topical treatment, phototherapy is one of the main treatments used. We carried out a prospective study of adult diffuse PLC treated with narrowband ultraviolet B (NB-UVB). We treated eight patients whose disease showed no response to topical therapy, and obtained a complete response rate of 88% in a mean of 23 sessions (cumulative dose 16.99 J/cm ). However, the relapse rate was 43% in the first 6 months. Our results are similar to those of other published studies but there is much variability between them in the doses applied and the number of sessions needed. Further studies are necessary to devise a protocol for NB-UVB treatment of PLC.
