A marked increase of dacrocytes is known as dacrocytosis. These tear drop cells are found primarily in diseases with bone marrow fibrosis, such as: primary myelofibrosis, myelodysplastic syndromes during the late course of the disease, rare form of acute leukemias and myelophthisis caused by metastatic cancers.
Myelophthisic anemia (or myelophthisis) is a severe type of anemia found in some people with diseases that affect the bone marrow. Myelophthisis refers to the displacement of hemopoietic bone-marrow tissue [1] by fibrosis, tumors, or granulomas. The word comes from the roots myelo-, which refers to bone marrow, and phthisis, shrinkage or atrophy.
In primary myelofibrosis, progressive scarring, or fibrosis, of the bone marrow occurs, for the reasons outlined above. The result is extramedullary hematopoiesis, i.e. blood cell formation occurring in sites other than the bone marrow, as the hemopoietic cells are forced to migrate to other areas, particularly the liver and spleen. This causes ...

Bone pain is a common complication of fibrous dysplasia. It may present at any age, but most commonly develops during adolescence and progresses into adulthood. [7] Bone marrow stromal cells in fibrous dysplasia produce excess amounts of the phosphate-regulating hormone fibroblast growth factor-23 (FGF23), leading to loss of phosphate in the ...
Dysplasia can affect all three lineages seen in the bone marrow. The best way to diagnose dysplasia is by morphology and special stains used on the bone marrow aspirate and peripheral blood smear. Dysplasia in the myeloid series is defined by: Granulocytic series [citation needed]:
The liver is then used as the main hematopoietic organ of the embryo until near birth, where it is then taken over by the bone marrow. [5] Most red blood cells are released into the blood as reticulocytes. Polychromasia occurs when the immature reticulocytes of the bone marrow are released, resulting in a grayish blue color of the cells.
The bone marrow histology should demonstrate the following: [2] A proliferation and atypia of the bone marrow cells that produce platelets (megakaryocytes) Reticulin fibrosis which doesn't exceed grade 1. Grade 2 or 3 is a diagnostic criteria for primary myelofibrosis. Age-adjusted cellularity
