Fingolimod-induced bladder lymphoma in a patient with multiple sclerosis

Abstract

Key Clinical MessageMalignancies were reported in some studies following taking Fingolimod. We reported a case of bladder lymphoma after taking Fingolimod. Physicians should consider the carcinogenic effects of Fingolimod in long-term use and replace it with safer medicines. Fingolimod is a medication with a potential cure to control multiple sclerosis (MS) relapses. Here we describe a 32-year-old woman with relapsing-remitting multiple sclerosis who developed bladder lymphoma induced by long-term use of Fingolimod. Physicians should consider the carcinogenic effects of Fingolimod in long-term use and replace it with safer medicines.
