Eczematid like purpura of Doucas and Kapetanakis

Eczematid-like purpura of Doucas and Kapetanakis is a medical term for a lymphocytic capillaritis of unknown cause. Lesions consist of erythematous and purpuric macules which usually begin around the ankles, coalesce, and spread to involve the whole legs, and sometimes the trunk and upper extremities. The lesions are extremely pruritic and occasionally lichenified after prolonged scratching.
