Stomatocytosis is a rare condition in which the central pallor of erythrocytes has the shape of a “mouth” or “slit”. Stomatocytosis can be hereditary or acquired. The latter is observed in alcoholism, liver diseases, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and thalassemia. It can also occur after the use of certain medications (for example, vinblastine preparations for the treatment of leukemia and lymphoma). Stomatocytosis is possible in heart defects. source: inst:xiaoning.zhang
