Codocyte - Wikipedia
Codocytes, also known as target cells, are red blood cells that have the appearance of a shooting target with a bullseye.
Peripheral Blood Smear - Clinical Methods - NCBI Bookshelf
Leptocytes (or wafer cells) are thin, flat cells with the hemoglobin at the periphery of the cell. Sickle cells (drepanocytes) are elongated, sometimes crescent-shaped, erythrocytes with pointed ends. Elliptocytes (ovalocytes) range from slightly oval to elongated cigar-shaped forms.
Target cells : Definition, Detection and Clinical Significance
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.
Leptocyte | definition of leptocyte by Medical dictionary
A target or Mexican hat cell, that is, an unusually thin or flattened red blood cell with a central rounded area of pigmented material, a middle clear zone that contains no pigment, and an outer pigmented rim at the edge of the cell.

2022年3月7日 · The other names for target cells are codocytes, Mexican hat cells (wavy bowl shape), and leptocytes (thinness). Target cells resemble the appearance of a shooting target with a bulls-eye but in electron microscope, target cells resemble the shape of a bell.

The Pathogenesis of Spherocytes and Leptocytes (Target Cells)
Bizarre shapes (poikilocytosis) are characteristic of red cells in the process of fragmentation and in some diseases of the bone marrow there are red cells shaped like tear drops, tennis rackets, dumb bells or belaying pins. Of immediate interest in this study are variations from the normal shape which involve the red cell's thickness.
leptocytes (Cytokines & Cells Encyclopedia - COPE)
In contrast to normal red blood cells, which show a clear central area, leptocytes are elongated or oval in shape and are pale-staining with hemoglobin, which is confined to a thin flat layer near the cell membrane, leaving a colorless clear center.

Red cell morphology and the peripheral blood film
Pale red cells, which are not small, are not microcytes; they are leptocytes. Not all small-diameter red cells should be called microcytes. Spherocytes, fragmented red cells (shistocytes or schizocytes), and irregularly contracted red cells, are small but are not pale.
