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.:701 The name "lupus pernio" is a misnomer, as microscopically this disease shows granulomatous infiltration and does not have features of either lupus nor pernio.
