Infliximab therapy for sarcoidosis (lupus pernio).

Sarcoidosis is a chronic granulomatous disease of unknown aetiology in which the primary cytokine tumour necrosis factor (TNF)-alpha appears to play a major role. Older immune-modulating drugs including corticosteroids, antimalarials and thalidomide, as well as cytotoxic drugs with immune modulatory effects, have been used to control disease. We present a patient with severe mutilating cutaneous sarcoidosis (lupus pernio) who had showed only partial response to courses of a wide spectrum of immune modulators and cytotoxic therapies, and who had developed significant side-effects due to prolonged high-dose corticosteroids. However, the patient's cutaneous disease responded rapidly to the TNF-alpha inhibitor infliximab.
