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. Such changes are often found in patients with solid tumors, prompting the treating physician to look for possible bone marrow metastasis. Other causes for dacryocytes in a blood smear are severe hemolytic anemia associated with an increased breakdown of red blood cells in the spleen and secondary splenomegaly with extramedullary hematopoiesis.

Below, the cause and differential diagnosis of teardrop red blood shapes in the microscopic examination of blood smears will be discussed, which plays a pivotal role in clarifying the cause of anemia, particularly in elderly patients. Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. A poikilocyte is an abnormally-shaped red blood cell. The differential diagnoses encompass . This is why it is important to communicate teardrop red blood cells in the comment of the microscopic assessment. [2] It is also thought that this can similarly occur when red blood cells with large inclusions are obstructed from passing through the microcirculation, and the portion containing the inclusion thus gets pinched, leaving a tailed end. In recent years, more labs are using automated analyzers that prepare and stain blood smears. TEAR DROP CELL (DACRYOCYTES) Unipolar tapered end with a blunt tip Increase number of tear drop RBC is a clue to a possible underlying marrow process. Bain BJ, Clark DM, Wilkins BS.
