Another Knizocyte

Another example of a knizocyte is seen in this slide. These forms are seen in conditions in which spherocytes are visible and in some types of hemolytic anemia.

Knizocytes

Knizocytes are difficult to find in ordinary smears. They can be described as having a streak of hemoglobin through the center of the cell. This is due to two or more indentations in the cell membrane as seen with the electron microscope. The mechanism for formation is unknown. A knizocyte can be seen in the center of this slide.

Keratocytes

Keratocytes are cells which have been damaged due to contact with fibrin strands. Since the cut is incomplete, however, no hemoglobin has been lost from the cell. Keratocytes have one or two projections which may vary in length from a short point to a longer string. These projections are formed when red cells come in contact with fibrin strands during circulation. Two keratocytes can be seen in this field. The one in the center to the left of the platelet has a lightly-stained projection. The keratocyte in the lower part of the screen is more pronounced. A knizocyte can be seen in the upper left portion of the field.
