A 72-year-old man developed chest pain whenever he was physically active. The pain ceased on stopping his activity. He has no history of heart or lung disease. His physical examination was normal except for notable pallor. Diagnostic Analysis The patient was experiencing a blood transfusion incompatibility reaction. His direct Coombs test and haptoglobin studies indicated some hemolysis because of the reaction. His platelet count dropped because of antiplatelet antibodies, probably the same ABO antibodies that caused the RBC reaction. He was given iron orally over the next 3 weeks, and his Hgb level improved. A rectal examination indicated that his stool was positive for occult blood. Colonoscopy indicated a rightside colon cancer, which was removed 4 weeks after his initial presentation. He tolerated the surgery well.
