hereditary xerocytosis

(zer?o-si-to'sis) [ xero- + cyto- + -sis]

A disorder of erythrocytes usually inherited as an autosomal dominant trait. A membrane defect in the red blood cells permits the loss of excess potassium ions and water, causing dehydration of the cells. Hemolysis and anemia range from mild to severe.
