[1] There may also be other features of the primary underlying pathology. Cell with slit-like central pallor; occasional stomatocytes are non-specific or an artefact; many are seen with rare hereditary stomatocytosis Target cell: Cell with central and peripheral staining with intervening pallor due to increased redundancy of RBC membrane; seen with liver disease, in some thalassemias, and with Hgb C Tear drop cell About 1% of ovalocytes are found in a normal complete blood count. A variety of tumors can lead to bone marrow metastasis. In the case of PMF, there are typically also dysmorphic platelets at the same time. London: Blackwell Science Ltd, 2001.10.1002/9780470757130Search in Google Scholar, 7. In summary, teardrop erythrocytes, in the presence of anemia, often indicate primary or secondary myelofibrosis. 000010151520140005. Conditions where teardrop cells are seen with high frequency may also have extramedullary hematopoiesis, particularly in the spleen (1,2). Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. Introduction to Myeloproliferative Neoplasms (MPNs), 88. 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.

Dysmorphic RBCs (e.g., sickle cells, target cells) have an altered form and are often a sign of an underlying condition. When the production of these blasts gets out of hand, they can spill from the bone marrow into circulating blood. Circulating blasts in the peripheral blood in these diseases may explain the reason for point to the possibility of myelofibrosis in these patients. It's sometimes called a peripheral smear for morphology. It may include blood transfusions or bone marrow transplants.
