Disulfite-induced acute intermittent urticaria with vasculitis.

Recognition of sulfite sensitivity by the practicing dermatologist has become increasingly important. A wide spectrum of anaphylactoid reactions can occur after ingestion of sulfite additives in foods and medications. We report the case of a 47-year-old man with severe acute intermittent urticaria. A placebo-controlled oral challenge test with 50 mg sodium disulfite resulted in an acute urticaria attack. A biopsy taken 5 h after the appearance of the urticaria demonstrated a leukocytoclastic vasculitis with eosinophilia. Avoiding foods and drugs containing sulfites is often difficult due to its widespread use. Therefore, the patient should be equipped with a medical emergency kit.

[Lupus erythematosus discoid-like dermatosis in a carrier of septic granulomatosis].

We present a clinically atypical case of discoid lupus erythematosus in the mother of a boy with chronic granulomatous disease. In this disorder, the phagocytes are unable to produce superoxide anion to degrade incorporated microorganisms. In addition to a discoid lupus erythematosus-like skin disease, recurrent stomatitis aphthosa, hidradenitis suppurativa and Raynaud phenomenon are markedly associated with heterozygote carriers of chronic granulomatous disease. Based on this conspicuous association, diverse models concerning the pathogenesis of lupus erythematosus are discussed.
