These lesions can be the presenting finding of the disease. Some of these lesions are nonspecific, but others are highly suggestive of sarcoidosis. Cutaneous anergy is common. Lesions resolve spontaneously in weeks. Papules and nodular lesions, such as these, are common and can be found anywhere on the body.
Papules are often multiple while nodules are often solitary.
Facial lesions are most common, but the extremities and buttocks can be involved. Lupus pernio lesions are indurated and violaceous and range from a few small lesions to large lesions as in this patient . These raised plaques are the result of coalescence of nodules. These small white lesions closely resemble psoriasis.
