Lupus chilblains is a unique form of Raynaud’s phenomenon, and it is identical in clinical presentation to pernio. It may be that this is just pernio occurring in a patient with lupus. Lupus chilblains and pernio manifest typically on the distal extremities, the toes being the most commonly affected region. The patient develops tender, cold, purplish papules and plaques. The rash is exacerbated by cold and wet environments.
