The purpose of the present study was to assess the efficacy of NB-UVB phototherapy in the management of pityriasis lichenoides (PL). Methods: The therapeutic response in 31 PL patients (23 pityriasis lichenoides et varioliformis acuta; PLEVA, eight pityriasis lichenoides chronica; PLC) treated with NB-UVB phototherapy between 2000 and 2007 was assessed. Results:NB-UVB treatment led to a complete response (CR) in 15 out of 23 PLEVA patients (65.2%) with a mean cumulative dose of 23 J/cm(2) after a mean number of 43.4 exposures and a partial response (PR) in eight patients (34.8%) with a cumulative dose of 15.6 J/cm(2) after a mean number of 32.3 exposures. NB-UVB treatment led to CR in seven out of eight PLC patients (87.5%) with a mean cumulative dose of 18.4 J/cm(2) after a mean number of 45.8 exposures and PR in one patient (12.5%) with a cumulative dose of 9.1 J/cm(2) after a mean number of 19 exposures. Relapses occurred in four PL patients within a mean time period of 6 months. Conclusion: NB-UVB therapy is an effective, safe and practical alternative treatment modality for the management of PLEVA and PLC.eninfo:eu-repo/semantics/closedAccessNarrowband UVB phototherapyPityriasis lichenoidesVarioliformis-acutaUltraviolet-radiationIrradiationExpressionTherapyLightDermatologyAdolescentAdultAgedChildFemaleHumansMaleMiddle agedPityriasis lichenoidesRadiation dosageRecurrenceRemission inductionRetrospective studiesTreatment outcomeUltraviolet therapyArticle0002558361000042-s2.0-4364909955012813324318477131DermatologyPityriasis Lichenoides; Febrile Ulceronecrotic Mucha-Habermann Disease; Lymphomatoid PapulosisAntibiotic agentMethotrexatePsoralenSteroidAdolescentAdultAgedArticleClinical articleClinical effectivenessControlled studyDisease severityErythemaFemaleHumanMalePatient safetyPityriasis lichenoidesPriority journalPUVARadiation doseRadiation exposureRelapseSchool childTreatment responseUltraviolet b radiationChildMethodologyMiddle agedPhototherapyPityriasis lichenoidesRecurrent diseaseRemissionRetrospective studyTreatment outcome
