True teardrop cells have slighly . Jun 28, · The presence of teardrop cells (dacrocytes) (Figure below) in the peripheral blood, named for their tear drop shape, is a prominent feature of myelophthisic (marrow infiltrative) conditions, including myelofibrosis, hematologic malignancies, cancer metastatic to the bone marrow, and granulomatous diseases.

The contrato de know how modelo of teardrop cells dacrocytes Figure below in the peripheral blood, named for their tear drop shape, is a prominent feature of myelophthisic marrow infiltrative conditions, including myelofibrosis, hematologic malignancies, cancer metastatic to the bone marrow, and granulomatous diseases.
Teardrop cells may also be seen in beta-thalassemia, autoimmune and microangiopathic hemolytic anemia and severe iron deficiency When evaluating patients with leucoerythroblastic smears defined by the presence of early myeloid and erythroid formsthe presence of teardrop cells can be helpful in distinguishing often malignant marrow infiltrative conditions from a benign reactive process.
Conditions where teardrop what are tear drop cells are seen with high frequency may also have extramedullary hematopoiesis, particularly in the spleen 1,2. The mechanism of teardrop cell formation may be multifactorial but appears to involve distortion of the red cells as they pass through marrow or splenic sinusoids. Teardrop cells resulting from conditions such as cancer metastatic to the bone marrow likely involve primarily a marrow origin of the cells whereas primary myelofibrosis with prominent extramedullary hematopoiesis include a splenic mechanism of teardrop cell formation 2.
