47+ Megaloblastic Anemia Hypercellular Bone Marrow Images. Megaloblastic anemia is a blood disorder marked by the appearance of very large red blood cells that crowd out healthy cells, causing anemia. Hypercellular with inreased erythropoiesis, which usually dominates (m:e ratio is lower than 1:1).
Megaloblastic Anemia - Causes, Symptoms, Treatment from healthjade.com Megaloblastic anemia is the result of a deficiency of vitamin b 12 and folic acid. Megaloblastic anemia, the production in the bone marrow of abnormal nucleated red cells known as megaloblasts, develops as the result of dietary deficiency of, faulty absorption of, or increased demands for vitamin b 12 or folic acid. Megaloblasts are large nucleated red blood cell precursors with noncondensed chromatin.
The aspirated marrow is often hypercellular with striking.
Absent or sparse erythroid precursors: In moderate to severe cases, the marrow is almost always hypercellular with brisk erythroid hyperplasia (small black arrows). Megaloblastic anemias are a group of disorders characterized by reduced dna synthesis (not just in red cell series) associated with pathognomonic the bone marrow is hypercellular with megaloblastic changes in both the red and white cell series. Megaloblastic anemia is a type of macrocytic anemia that results from inhibition of dna synthesis during red blood cell production.
