Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. In primary myelofibrosis, a change in the DNA of a single hematopoietic stem cell causes the abnormal cell to continually reproduce itself. Both, the suspicion of primary myelofibrosis (PMF) and the suspicion of bone marrow infiltration by tumor cells should always be followed up with further bone marrow diagnostics. Polychromasia, as well as the specific blood disorders that cause it, can be diagnosed via a blood smear test. What does the presence of ovalocytes mean?
