Abstract

Pigmented purpuric dermatosis (PPD) represents a group of cutaneous lesions exhibiting petechiae, pigmentation, andoccasionally telangiectasia in the absence of an associated venous insufficiency or hematological disorder. PPD mayresolve spontaneously but tends to persist for months to years. Various treatment modalities such as oralgriseofulvin, pentoxifylline, cyclosporine, ascorbic acid, topical corticosteroids, and PUVA therapy have been usedwith unsatisfactory results. Recently, some studies reported that PPD showed a dramatic response to narrowbandultraviolet B (UVB) phototherapy. In these studies, narrowband UVB phototherapy was an effective treatmentmethod with few side effects. Here, we present the case of a 7-year-old boy with generalized PPD that improvedrapidly following narrowband UVB phototherapy. (Korean J Dermatol 2015;53(1):49∼52)
