Pigmented purpuric eruptions of childhood: A series of cases and review ofliterature

Pigmented purpuric eruptions comprise a group of benign dermatoses that are characterized clinically by pinpoint petechiae and purpura on a hyperpigme nted base and histologically by capillaritis. The etiology of this group of disorders is unknown, although aberrant cell-mediated immunity has been pr oposed. Pigmented purpuric eruptions are well characterized in the pediatri c population. In this case series we present three children with these diso rders and review the clinical subtypes of pigmented purpuric eruptions that have been described in the literature.
