Megaloblastosis can be associated with severe anemia and pancytopenia, gastrointestinal dysfunction and glossitis, personality changes. Macrocytosis without anemia may be a normal variant and is only noted as a result of repeated peripheral RBC indices in the absence of any known or existing.

Macrocytic anemia describes an anemic state characterized by the presence of abnormally large RBCs in the peripheral blood. Erythrocyte mean corpuscular volume as a surrogate marker for 6-thioguanine nucleotide concentration monitoring in patients with inflammatory bowel disease treated with azathioprine macrocittica 6-mercaptopurine.

However, its macrkcitica can provide important information regarding the presence of an underlying disease state. For patients who present with disordered immaturity, hypogranulated or hyposegmented neutrophils, and cytopenias, a bone marrow examination is necessary to rule out or confirm a primary bone marrow disorder such as a myelodysplastic syndrome or leukemia. No complications arise from macrocytosis itself as an isolated finding.
