In literature, six different types of pigmented purpuric dermatosis, namely "Schamberg's disease, Purpura of Majocchi, Lichen aureus, Lichenoid purpura of Gougerot and Blum, Eczematoid-like purpura of Doucas and Kapetanakis and Itching purpura", are described. 1Histologically, in all the variants, erythrocyte extravasation with hemosiderin deposition and perivascular lymphocytic infiltrate in the papillary as well as in mid-dermis is seen.A lichenoid pattern of lymphocytic infiltrate is seen in "Lichen aureus and Lichenoid purpura of Gougerot and Blum". 2inically, "Lichenoid purpura of Gougerot and Blum" is characterised by small lichenoid papules which eventually fuse at certain locations to form plaques of various hues, 3 commonly affecting men of middle age.
