Narrowband UVB treatment of pigmented purpuric lichenoid dermatitis (Gougerot–Blum)

Abstract

Summary Pigmented purpuric dermatoses are a group of dermatoses characterized clinically by pinpoint petechia and purpura on a brown, red or yellow base. Five diseases are included in the group of pigmented purpuric eruptions which significantly overlap clinically and histologically. Phototherapy in various forms of purpuric dermatoses has been reported in literature previously. Here we present a case of pigmented purpuric lichenoid dermatitis which rapidly cleared with narrowband UVB therapy.

Two cases of eczematid‐like purpura of Doucas and Kapetanakis responsive to narrow band ultraviolet B treatment

“…PPDs are divided into five clinical groups, including progressive PPD (Schamberg's disease), purpura The etiology of the disease is still unknown. The postulated etiological factors include gravity and increased venous pressure, capillary fragility, exercise, focal infections, chemical foods, medications, contact with aniline paints, and alcohol consumption (3,4).…”

Treatment of pigmented purpuric dermatoses with Narrow‐band UVB: a report of six cases

“…However, with further reduction of the frequency of NB UVB the lesions flared. 17 Kocaturk et al 2 reported a case of pigmented purpuric lichenoid dermatitis that improved markedly with 20 treatments of NB UVB followed by another 10 sessions of light therapy, given as a maintenance therapy with total cumulative dose of 27 J ⁄ cm 2 . To the best of our knowledge, there is no previous report indicating treatment of Majocchi's purpura with light therapy.…”
