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.AbstractFingolimod 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.
