Abstract

|
Pigmented purpuric dermatoses (PPD) are a group of diseases characterized by petechiae and bronze discoloration of the skin on the lower extremities. Histopathologically, superficial perivascular lymphocytic infiltration and hemosiderin deposition are seen. PPD can be subdivided into progressive pigmentary dermatosis of Schamberg, purpura annularis telangiectoides of Majocchi, pigmented purpuric dermatitis of Gougerot and Blum, eczematid-like purpura of Doucas and Kapetanakis, itching purpura, and lichen aureus. The granulomatous variant of PPD was described in 1996. Granulomatous PPD share common histopathologic features of PPD with granulomatous inflammation. We present the findings of a patient who presented with a clinical picture of PPD and histologic patterns of granulomatous inflammation.
