Sarcoidosis, an inflammatory disease, involves the skin in about 25% of patients. The most common lesions areerythema nodosum, plaques,maculopapular eruptions, subcutaneous nodules, andlupus pernio. Treatment is not required, since the lesions usually resolve spontaneously in two to four weeks. Although it may be disfiguring, cutaneous sarcoidosis rarely causes major problems.[1]
