A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell"). A marked increase of dacrocytes is known as dacrocytosis.

2016年1月13日 · •Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. They can also be seen in patients with splenic abnormalities, vitamin B12 deficiency, and some other forms of anemia.

Background: Dacryocytes are teardrop-shaped erythrocytes which are most frequently observed in peripheral blood smears of patients with primary or secondary myelofibrosis as well as malignant infiltrative disorders of the bone marrow.

2006年11月1日 · These abnormal erythrocytes have a teardrop, or pearlike, shape. They are associated with disorders with an abnormal spleen or bone marrow, such as idiopathic myelofibrosis, thalessemia, or myelophthisis. Peter Maslak, …

2019年6月28日 · 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.

2014年3月15日 · Teardrop erythrocytes (syn. dakryocytes) play a key role in the evaluation of peripheral blood smears in patients with anemia, especially as part of the “leukoerythroblastic picture”. Teardrop-shaped red blood cells can be seen in a wide range of diseases that lead to bone marrow fibrosis, which is often accompanied by extramedullary hematopoesis.

Dacrocyte, Elliptocyte and Schistocyte cells are three essential Poikilocyte cells that are prevalent in IDA. The suggested cell recognition approach includes preprocessing, segmentation, feature extraction and classification steps.
