A 58-year-old female was admitted with abdominal pain for 2 years and diarrhea for 1 year. Examination showed tenderness over hypogastrium and right iliac region. Hemoglobin was 10.3 g/dl (normocytic, normochromic), total white blood cell count 4900/µl, platelet count 0.94 × 109/L, and erythrocyte sedimentation rate 56 mm in 1 h. Peripheral smear showed normocytic normochromic anemia with evidence of microangiopathic hemolysis; occasional microspherocytes, schistocytes, polychromatophilic cells, nucleated red blood cells (RBCs), and mild thrombocytopenia [[Figure 1] upper panel]. Her corrected reticulocyte count was 4%, serum lactate dehydrogenase 1821 U/L, and the direct and indirect Coombs tests were negative. Prothrombin time and partial thromboplastin time were normal. Stool and blood cultures were sterile. Liver function tests showed indirect hyperbilirubinemia with normal enzymes. Colonoscopy revealed Grade 3 left-sided colitis. Colonoscopic biopsy showed ulcerative colitis [[Figure 1] lower panel]. She was started on mesalazine and steroids with which she improved.

Microangiopathic hemolytic anemia (MAHA) is characterized by fragmented RBCs and thrombocytopenia that is nonimmune in nature. MAHA can be associated with a variety of diseases including thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, disseminated intravascular coagulation, preeclampsia, eclampsia, malignant hypertension, drugs, and autoimmune disorders. Hemolysis in ulcerative colitis may be due to autoimmune hemolytic anemia. MAHA as a manifestation of active ulcerative colitis is extremely rare.
