title: Pigmented purpuric eruptions of childhood: a series of cases and review of literature.
abstract: Pigmented purpuric eruptions comprise a group of benign dermatoses that are characterized clinically by pinpoint petechiae and purpura on a hyperpigmented base and histologically by capillaritis. The etiology of this group of disorders is unknown, although aberrant cell-mediated immunity has been proposed. Pigmented purpuric eruptions are well characterized in the pediatric population. In this case series we present three children with these disorders and review the clinical subtypes of pigmented purpuric eruptions that have been described in the literature.
