What do your white blood cells look like? Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. For instance, myelofibrosis can be quickly diagnosed using this integrated manner using cytopenia(s) as criterium/criteria in combination with the detection of teardrop cells. How are teardrop cells used to diagnose myeloid leukemia? As myelofibrosis can also be observed in other progressive myeloproliferative diseases (MPN) as well as essential thrombocythemia (ET) and polycythemia vera (PV), teardrop shapes are not pathognomonic of PMF, but may also be observed in other bcr-abl negative MPNs, bcr-abl positive CML and in advanced stages of myelodysplastic syndrome (Figure 2B,C). 2 Red blood cells, so nice and simple.
