Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. Can I estimate the central venous pressure (CVP) of my patient with dyspnea at the bedside by using point of care ultrasound (POCUS)? Is loss of sense of smell or taste much less common in Omicron-related Covid-19 compared to earlier strains of SARS-CoV-2? The blood count at this stage often shows thrombocytopenia, anisocytosis with numerous teardrop shapes and a normochromic to hypochromic anemia. Interested in more discussions like this?

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. When the blood count shows pancytopenia, it is helpful to not only focus attention on erythrocyte morphology, but also to screen the smear for atypical lymphoid cells.

Normal erythrocytes : pinkish red with lighted coloured centre. Warner EA, Herold AH. What does an abnormal blood smear showing tear drop cells, ovolacyes, and anisocitosis mean? In myelofibrosis, a complete blood count typically shows abnormally low levels of red blood cells, a sign of anemia common in people with myelofibrosis. Complications from poikilocytosis vary and stem for the root disorder causing the abnormal cells. Plus, the shape of the small slit may be distorted, which can increase the amount of time needed to get through it. Content on HealthUnlocked does not replace the relationship between you and doctors or other healthcare professionals nor the advice you receive from them. In summary, teardrop erythrocytes, in the presence of anemia, often indicate primary or secondary myelofibrosis. When the production of these blasts gets out of hand, they can spill from the bone marrow into circulating blood. dakryocytes) play a key role in the evaluation of peripheral blood smears in patients with anemia, especially as part of the "leukoerythroblastic picture".
