Acanthocytosis is a condition characterized by the presence of abnormally-shaped red blood cells called acanthocytes. Signs and symptoms more commonly reported 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. Some individuals hvae may have ataxia, tremors, and visual abnormalities; or jaundice, abdominal pain, pallor, dark urine, and recurrent infections. Although acanthocytosis has been associated with a number of both inherited and acquired conditions, it most commonly occurs with abetalipoproteinemia and hemolytic anemia of severe liver disease. Treatment for acanthocytosis depends on the underlying condition the affected individual has.[1][2]
