Ulcerative Sarcoidosis: Case Report and Review of the Japanese Literature

,Sarcoidosis is a chronic multi-system disease of unknown origin involving the eyes, skin, lungs, heart, bones and nerves. Skin lesions are relatively common, and are clas-sified as either specific or non-specific (1). Specific le-sions are those that show the typical sarcoid granulomas, including lupus pernio, infiltrated plaques, maculopapular eruptions, subcutaneous nodules and infiltration of old scars (1). The most typical non-specific skin lesion is erythema nodosum. The patient described here had skin lesions that first suggested a diagnosis of erythema indu-ratum of Bazin, but we ultimately diagnosed sarcoidosis based on other findings, including uveitis, bilateral hilar lymphadenopathy, an increased level of serum angio-tensin-converting enzymes (ACE) and a negative response to purified protein derivative of tuberculin (PPD).
