cayenne pepper appearance
A descriptive term for the appearance of hyperpigmented and petechial lesions of the lower legs, arms and trunk, related to idiopathic capillaritis, which has been fancifully likened to that of cayenne pepper.
The appearance is classically described in Schamberg disease–progressive pigmented purpuric dermatitis, but is also seen in purpura annularis telangiectodes (Majocchi disease), lichen aureus, itching
purpura, eczematid-like purpura of Doucas and Kapetanakis, and pigmented purpuric lichenoid dermatosis of Gougerot and Blum; the change may also be caused by a drug reaction.
