Schamberg's Disease: Schamberg’s disease is a form of progressive pigmented purpuric dermatosis. This type of nonpalpable purpura consists of reddish-brown macules that are usually located on the lower extremities and ankles, and spare the soles of the feet. These petechiae appear due to capillary leakage and breakdown of blood near the skin surface, leaving behind hemosiderin deposits.
