Overview

Bone marrow disorders are classified into congenital bone marrow disorders and acquired bone marrow disorders.

Definition of Terms

Bone marrow suppression: Reduced numbers of cells in the bone marrow
- Myelosuppression: Reduced number of myeloid lineage cells (RBC, neutrophils, basophils, eosinophils, monocytes, platelets, mastocytes)
- Immunosuppression or lymphosuppression: Reduced number of lymphoid lineage cells (T-cell, B-cell, NK cell)

Bone marrow proliferation: Increased numbers of cells in the bone marrow
- Myeloproliferation: Increased number of myeloid lineage cells (RBC, neutrophils, basophils, eosinophils, monocytes, platelets, mastocytes)
- Immunoproliferation or lymphoproliferation: Increased number of lymphoid lineage cells (T-cell, B-cell, NK cell)
