Development of cutaneous sarcoidosis during treatment with tumour necrosis alpha factor antagonists.

ABSTRACT

The use of tumour necrosis factor alpha (TNF-α) antagonists is increasing in the field of dermatology. These agents have been used for multiple inflammatory and immune skin conditions, but most notably, psoriasis. Adverse effects of anti-TNF-α agents have been reported, including the paradoxical development of sarcoidosis. We present an unusual case of limited cutaneous sarcoidosis developing while the patient was on etanercept therapy, and a review of the current literature.
