Abstract

Perniosis is a localized, inflammatory reaction that ischaracterized by erythematous papules and nodulesthat often are located on the acral surfaces in youngwomen. The lesions of perniosis are thought to bedue to cold-induced vasoconstriction that leadsto hypoxemia and inflammation of the vessel wall.Histopathologic and laboratory studies are indicatedfor patients with suspected perniosis to distinguishbetween idiopathic perniosis and secondaryperniosis. Treatment includes adequate heating andclothing, proper food intake, nifedipine, ultravioletA1 phototherapy, topical glucocorticoids, andvasodilators.
