Chapter 70. Persistent Pigmented Purpuric Dermatitis

Definition

An inflammatory process, but not a vasculitis, that involves the legs especially with purpuric macules and subtle papules (Schamberg’s disease), lichenoid papules (lichenoid purpura of Gougerot-Blum), and scaly papules (eczematid-like purpura of Doucas and Kapetanakis), all of which seem to be variants of the same basic pathologic process.
