Pigmented purpuric dermatoses

The term pigmented purpuric dermatoses comprehends the following entities: Schamberg’s disease, Majocchi purpura, eczematoid purpura of Doucas and Kapetanakis, lichen aureus and pigmented purpuric lichenoid dermatitis of Gougerot-Blum. Pigmented purpuric dermatoses are dermoscopically identified by the combination of purpuric dots or globules and orange-brown areas of pigmentation.[1][2] A similar dermoscopic pattern has been described in patients with mycosis fungoides, supporting previous evidence reporting clinical and histopathologic overlap between the two entities.[3] Since the pigmented purpuric dermatoses and mycosis fungoides notably differ in physical course and management, lesions showing a dermsocopic pattern of pigmented purpuric dermatoses should be evaluated carefully.
