What are dacrocytes?
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.
What teardrop cell means?
The presence of teardrop-shaped cells may indicate: Myelofibrosis. Severe iron deficiency. Thalassemia major. Cancer in the bone marrow.

What is Fanconi’s Anaemia?
Fanconi anemia is a rare disease passed down through families (inherited) that mainly affects the bone marrow. It results in decreased production of all types of blood cells. This is the most common inherited form of aplastic anemia. Fanconi anemia is different from Fanconi syndrome, a rare kidney disorder.
Why are dacrocytes formed?
Teardrop cells (Dacrocytes) are thought to form as a result of the removal of an inclusion from the cell as it moves through the spleen. This process is referred to as pitting.
What causes tear drop RBCs?
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.
