Chilblain lupus erythematosus.

Rare variant of cutaneous lupus erythematosus, whose skin changes are reminiscent of frostbite (= chilblain). Caution: Do not confuse with lupus pernio, which is a variant of sarcoidosis!

  • < 100 cases described.
  • So far, almost only with women.
  • Occurs at low temperatures.

The exact cause is unknown. There is at least one genetic component, since family forms of "chilblain lupus" are described.

Livid pressure umbels, partly hyperkeratotic, sometimes hyperesthetic, cushion-like swellings, plaques and knots. Central atrophy, erosion or ulcers can occur. 

  • S. Cutaneous lupus erythematosus.
  • Note:
    • Frequently increased: γ-Globulins, ANAs, ds-DNA-Ak, antiphospholipid-Ak, anti SSA/Ro, BSG, pos. rhesus factor.
    • Association with SLE in approx. 20%.

Areas exposed to cold.

Orthohyperkeratosis, atrophy of the surface epithelium, perivascular lymphocellular infiltrates, intraluminal fibrin deposits.

Transition to an SLE.

Often chronic.

  • Consistent protection against cold.
  • S. Cutaneous lupus erythematosus.
