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.
The authors describe a case of conjunctival mucosa-associated lymphoid tissue lymphoma associated with fingolimod treatment for multiple sclerosis and warn that lymphoma may be an adverse event linked to fingolimod therapy.
