Red Cell Disorders: Peripheral Blood Clues to Nonneoplastic Conditions

Stomatocytes

Stomatocytes are erythrocytes with a slit-like central pallor. Otherwise, they resemble typical RBC's in size and shape. Unless 10% or more of the RBC's are stomatocytes, their presence is probably artifactual. Stomatocytes form at a low blood acidic pH as seen in exposure to cationic detergents, and in patients receiving phenolthiazine. Hereditary stomatocytosis has some resemblance to hereditary spherocytosis, as stomatocytes may develop into spherocytes with further metamorphosis. In hereditary stomatocytosis, mild anemia and findings of on-going hemolysis should be evident if the condition presents as a clinical problem at all.

Examples of Stomatocytes Examples of stomatocytes can be seen in the center of this slide and to the left of the center. Conditions in which a significant number of in vivo stomatocytes can be seen include hereditary stomatocytosis, neoplastic disorders, liver disease and Rh null disease. The largest numbers of in vivo stomatocytes are seen in hereditary stomatocytosis and their identification is necessary to make the diagnosis.	View Page

Stomatocyte The term, stomatocyte, is derived from the Greek term, stoma, meaning mouth. Stomatocytes are cup-shaped erythrocytes which have an elongated or slit-like central pallor. The occasional stomatocyte seen in normal smears is the result of a slight pH change in the environment similar to the in vitro changes which cause cells to assume the echinocyte shape. A stomatocyte can be seen in the center of this slide.	View Page
