Conjunctival Lymphoma in a Patient on Fingolimod for Relapsing-Remitting Multiple Sclerosis
The authors describe a 39-year-old woman treated with fingolimod for relapsing-remitting multiple sclerosis for 2 years who then developed a bilateral conjunctival mucosa-associated lymphoid tissue lymphoma. Fingolimod treatment for multiple sclerosis has been associated with lymphoma in 3 previously reported cases. This is the first case of ocular adnexal lymphoma presumed to be due to fingolimod. Given that ophthalmologists regularly monitor many patients on fingolimod for fingolimod-associated macular edema and ophthalmic manifestations of multiple sclerosis, the authors hope to alert physicians of the possibility of ocular adnexal lymphoma in these patients.
