A Case of Multisystem Inflammatory Syndrome in an Immunosuppressed Adult

Multisystem inflammatory syndrome in an adult (MIS-A) is a rare immunological complication that gained prominence after the coronavirus disease 2019 pandemic. Patients with MIS-A often clinically present with non-specific generalized symptoms, such as fever, myalgia, or fatigue, making the diagnosis difficult. In this article, we present an unusual case of MIS-A in a 50-year-old male that raises the question of whether the immune system’s dysregulation will demonstrate differing criteria of signs and symptoms for a patient on sustained immunosuppression as opposed to the non-immunosuppressed population.
