SpecialtyDermatology

Lupus pernio is a chronic raised indurated (hardened) lesion of the skin, often purplish in color. It is seen on the nose, ears, cheeks, lips, and forehead. It is pathognomonic of sarcoidosis. The name "lupus pernio" is a misnomer, as microscopically this disease shows granulomatous infiltration and does not have features of either lupus nor pernio.
