Teardrop erythrocytes are especially common with PMF [1] and in connection with other advanced myeloproliferative neoplasms and primary MDS, which may be accompanied by a pronounced fibrosis during the late stage. However, in the case of lymphomatous infiltration of the bone marrow, teardrop shapes are encountered in the blood smear far less often, since infiltration often does not affect the whole bone marrow and is not accompanied by EMH. Symptoms of poikilocytosis depend on the root medical condition. Dacryocytes (similar to fragmentocytes) in a blood smear are not a substitute for the detection of extramedullary hematopoiesis or myelofibrosis, but serve as an important indicator during the search for the cause of anemia.

No worry: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell"). The protective functions of blood include clot formation and the prevention of infection. An abnormal result occurs when the shape, color, or size of the red blood cells are not normal.. Common causes of abnormal red blood cells include: While poikilocytosis occurs in about 12% of cancer patients, anemia or uremia may or may not be present. iron deficiency anemia, myelodysplastic syndrome-refractory anemia/MDS-RA, refractory anemia with ringed sideroblasts/RARS). The following excerpt is from the link below. In summary, teardrop erythrocytes, in the presence of anemia, often indicate primary or secondary myelofibrosis.
