Orbital Sarcoid-Like Granulomatosis After Inhibition of Tumor Necrosis Factor-α.

Pharmacologic inhibition of tumor necrosis factor-alpha (TNF-α) has been used in the management of a variety of inflammatory conditions. Recently, reports on the development of sarcoid-like granulomatous disease at multiple systemic sites after treatment with TNF-α inhibitors have emerged, although, to the authors' knowledge, orbital manifestations of this problem have not been previously described. A 48-year-old woman who received injections of adalimumab for the treatment of psoriatic arthritis developed right-sided orbital pain and inflammation. Orbital biopsy of a focal lesion demonstrated sarcoid-like granulomatosis, and a workup for other causes of this problem was noncontributory. This report represents the first documented case of this phenomenon in the orbit, and possible mechanisms are discussed in this presentation. Given the expanding role of TNF-α inhibitors and the increased frequency of their use, clinicians should be aware of this possible side effect.
