Evans syndrome is a rare autoimmune disorder characterized by autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP), often linked with systemic lupus erythematosus (SLE). We present a case of a 25-year-old female with a history of rheumatoid arthritis (RA) who presented with new SLE symptoms, including left-sided weakness, pallor, and a photosensitive rash. Laboratory tests confirmed Evans syndrome, and MRI showed a cerebral infarction. Treatment with corticosteroids, hydroxychloroquine, and mycophenolate mofetil led to significant improvement. This case highlights the complexity of managing Evans syndrome in patients with coexisting autoimmune diseases like RA and SLE, emphasizing the need for early and aggressive treatment.
