Skin Lesions

One-third of patients with sarcoidosis have skin lesions. 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.

Skin Lesions in Sarcoidosis

• Erythema nodosum
• Lupus pernio
• Papules, nodules, and plaques
• psoriatic like lesions
• lesions in scars and tattoos

The acute triad of erythema nodosum, joint pains, and bilateral hilar adenopathy, LOFGREN'S SYNDROME, is highly suggestive of sarcoidosis.

ERYTHEMA NODOSUM	SMALL NODULES
These reddish raised lesions are common in sarcoidosis but also occur in other diseases. 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.

LUPUS PERNIO	LUPUS PERNIO
Lupus pernio is characteristic of chronic sarcoidosis. 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 .

RAISED PLAQUES	PSORIASIS LIKE LESIONS
These raised plaques are the result of coalescence of nodules.	These small white lesions closely resemble psoriasis.
