The patient was a 35-year-old pregnant woman (gravida 2, para 1). A routine blood test at 28 weeks of gestation revealed moderate macrocytic anemia. Her haptoglobin level was markedly low, and a direct antiglobulin test (DAT) was positive. Based on these results, AIHA was considered. A healthy female newborn with bodyweight 3575 g was vaginally delivered uneventfully. After delivery, the DAT remained positive, but anemia did not develop. At 203 days after delivery, ITP was detected. Because AIHA and ITP developed sequentially, she was diagnosed with Evans syndrome. When AIHA occurs during pregnancy, long-term follow-up is needed because ITP can develop sequentially.
