Eyelid Merkel cell carcinoma in a patient treated with golimumab.

Purpose: To describe a clinical case of biopsy-proven Merkel cell carcinoma of the eyelid following golimumab therapy for rheumatoid arthritis (RA).

Methods: Interventional case report.

Results: A 73-year-old woman with a history of chronic RA presented with a right upper eyelid mass. She had been treated with golimumab (tumor necrosis factor (TNF) inhibitors) injection therapy for the past 6 months. A biopsy showed findings suggestive of a Merkel cell carcinoma of the eyelid.

Conclusions: Merkel cell carcinoma may be associated with anti-TNF treatment and should be included in the differential diagnosis of an eyelid tumor in patients treated with TNF inhibitors.
