Codocytes, also known as target cells, are red blood cells that have the appearance of a shooting target with a bullseye.

2022年3月7日 · Codocytes or popularly known as target cells are formed if the red blood cell’s surface is increased disproportionately to its volume. Target cells are actually red blood cells, which are extremely thin and have an excessive cell membrane. Hence, the red blood cells assume the shape of a bell while in circulation.

2016年1月13日 · Target cells, or codocytes, have an excess of cell membrane relative to cell volume. Macrocytic target cells can be seen in liver disease, and microcytic target cells may be seen in thalassemia. Target cells may also be seen in hemoglobin C and E disease, and following splenectomy; they can also occur as an artifact of slide preparation.

Target cells adopt a “bullseye” morphology where hemoglobin is concentrated in the center and on the periphery with a colourless zone in between the two areas. Other target cells may also look folded or bell shaped. 1-3. Note: The target cell membrane …

Target cells, also known as codocytes or leptocytes, is a unique morphology of red blood cells characterized by a central, round hemoglobin area surrounded by a rim of paler staining. This distinctive appearance is caused by an increased surface-to-volume ratio of the RBCs due to excess membrane or decreased hemoglobin content.

Synonym (s): codocyte, leptocyte, Mexican hat cell. An erythrocyte in target cell anemia, with a dark center surrounded by a light band that again is encircled by a darker ring, thus resembling a target used in practice with firearms or archery; such cells also appear after splenectomy. Synonym (s): leptocyte, Mexican hat cell.

Codocyte (from the Greek term for “hat”) Definition: Centrally located disk of hemoglobin surrounded by an area of pallor with an outer rim of hemoglobin adjacent to the cell membrane giving the cell the appearance of a bull’s eye or shooting. …
