Abstract

Pigmented purpuric dermatosis (PPD) represents a group of cutaneous lesions exhibiting petechiae, pigmentation, and occasionally telangiectasia in the absence of an associated venous insufficiency or hematological disorder. PPD may resolve spontaneously but tends to persist for months to years. Various treatment modalities such as oral griseofulvin, pentoxifylline, cyclosporine, ascorbic acid, topical corticosteroids, and PUVA therapy have been used with unsatisfactory results. Recently, some studies reported that PPD showed a dramatic response to narrowband ultraviolet B (UVB) phototherapy. In these studies, narrowband UVB phototherapy was an effective treatment method with few side effects. Here, we present the case of a 7-year-old boy with generalized PPD that improved rapidly following narrowband UVB phototherapy.
