Hemoglobin H disease is a form of α-thalassemia disease resulting in mild to moderate hemolytic anemia. The authors report 1 case of a girl who was diagnosed with oculo-auriculo-vertebral spectrum and a coinheritance of hereditary elliptocytosis and deletional hemoglobin H disease. She had moderate, non–transfusion-dependent anemia. The red blood cells showed marked poikilocytosis and fragmentation. The parents were α-thalassemia carriers and the father had the typical red blood cell morphology of common hereditary elliptocytosis. *Department of Pediatrics, Division of Hematology and Oncology †Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand The authors declare no conflict of interest.
