Acanthocytosis is a condition which is characterized by the presence of abnormally-shaped red blood cells called acanthocytes (from the Greek work acantha, which means thorn). Although acanthocytosis has been associated with a number of both inherited and acquired conditions, it is most commonly observed in abetalipoproteinemia and hemolytic anemia of severe liver disease. The symptoms more commonly reported with acanthocytosis include a history of chronic diarrhea with pale, foul-smelling, and bulky stools; loss of appetite and vomiting; and slow weight gain and decreased growth. Treatment for acanthocytosis depends on the underlying condition.
