Tear Drop Cells

Would you like to know what lab results mean? Medical Tests Analyzer Software will explain and clarify your lab test report.

Pear Shaped Red Cell. A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell"). A proliferation of dacrocytes is known as "dacrocytosis".

Test results
Found in myelofibrosis, when bone marrow is replaced by non-haemopeitic tissue, and with extramedullary erythropoiesis

Definitions of cells by shape
Cell which is approximately spherical in shape so that it has lost its central pallor; the cell outline is regular
Spherocyte of reduced size and therefore diameter
Irregularly contracted cell
Cell of reduced size and diameter with a lack of central pallor but with an irregular outline
Cell with an elliptical outline
Cell with an oval outline
Tear drop poikilocyte
Cell shaped like a tear, less often known as a dacrocyte
Target cell
Cell with a more strongly staining area in the centre of the area of central pallor
Cell with a central slit or stoma
Cell with two or four curved horn-shaped projections
Schistocyte (red cell fragment)
Fragment of a cell, usually angular; a microspherocyte is a particular type of schistocyte
Echinocyte (crenated cell)
Cell with its surface covered with 20–30 small, regular, blunt projections
Cell with its surface covered with two to twenty projections of irregular shape and irregularly distributed
Sickle cell
Cell with a sickle or crescent shape, caused by the presence of a high concentration of an abnormal haemoglobin known as haemoglobin S
Boat-shaped cell
Cell similar in shape to an elliptocyte but with both ends being pointed, usually indicative of the presence of haemoglobin S
SC poikilocyte
Bizarre poikilocyte formed when cells contain both haemoglobin S and haemoglobin C, having some curved edges and some square or rectangular protrusions
