Abstrakt
In sum, persistent pigmented purpuric dermatoses are one nosological entity with clinical variations. Those variations are: (i) macular (Schamberg's purpura pigmentosa progressiva); (ii) annular (Majocchi's purpura annularis telangiectodes); (iii) scaly papular (Ducas-Kapetanakis' itching purpura); and (iv) lichenoid papular (Gougerot-Blum's lichenoid purpura).
Histopathologically, it is a superficial perivascular and interstitial dermatitis (macular and annular variant), a superficial perivascular, interstitial and spongiotic dermatitis (scaly papular variant), and a superficial perivascular, interstitial and lichenoid dermatitis (lichenoid papular variant).
