SINCE 1896, there has been described, although almost exclusively in the dermatologic literature, a group of purpuric pigmented eruptions having variable clinical features with individual eponyms, but having similar histopathologic alterations. In two variants of this general disorder described successively by Majocchi1-3 and Schamberg,4 the clinical and histologic findings are frequently so similar that differentiation is irrelevant. Accordingly, an inclusive designation of chronic pigmentary purpura has been proposed.5

Although a well-established entity in adult dermatology, chronic pigmentary purpura has been, to our knowledge, previously reported in preadolescent children only on four other occasions.4,6-8 It is important that this disorder be recognized and distinguished from other more serious purpuras of childhood. This report describes the clinical and pathologic findings of a case of chronic progressive pigmentary purpura occurring in a young boy.
