Why Does My Young Female Patient Have Recurrent Spontaneous Pneumothoraces? Teardrop cells resulting from conditions such as cancer metastatic to the bone marrow likely involve primarily a marrow origin of the cells whereas primary myelofibrosis with prominent extramedullary hematopoiesis include a splenic mechanism of teardrop cell formation (2). There should be more than one teardrop erythrocyte in a blood smear to warrant a comment in the microscopic assessment. Correspondence: PD Dr. med Ines Gtgemann, Institut fr Pathologie, Universittsklinikum Bonn, Sigmund Freud Str. The tear drop appearance is strongly indicative of a packed marrow.

Typically, the affected RBCs are small, spherically shaped, and lack the light centers seen in normal, round RBCs. White blood cell and platelet counts are usually abnormal, too. 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. In the peripheral blood, teardrops are particularly often observed in advanced cases of PMF, where a significant increase in the fiber volume has already occurred. This is why it is important to communicate teardrop red blood cells in the comment of the microscopic assessment. When evaluating patients with leucoerythroblastic smears (defined by the presence of early myeloid and erythroid forms), the presence of teardrop cells can be helpful in distinguishing often malignant marrow infiltrative conditions from a benign reactive process.
