    Abstract:
    Megaloblastic anemias are basically caused by vitamin B(12) and/or folic acid deficiency. Childhood vitamin B(12) deficiency is extremely rare. There are congenital and acquired forms of vitamin B(12)-deficiency anemias. The article captures findings of 10 year observation of 3 patients with Imerslund-Gräsbeck Syndrome (congenital chronic megaloblastic anemia with proteinuria), in which the diagnosis was established by us in early childhood and due to correct treatment and prevention complete clinical-laboratory remission is kept so far. We have also observed rare case of acquired megaloblastic anemia - 14 years old vegetarian patient, who was diagnosed with vitamin B(12)-deficiency anemia based on history, clinical and para-clinical data. It was caused by strict vegetarianism of the patient. Therefore first of all the diet was corrected. In 5 days of specific treatment with vitamin B(12) "reticulocyte crisis" was manifested (proving the correctness of diagnosis and treatment) and complete clinical-hematological remission was achieved in 2 weeks. The given cases are interesting as megaloblastic anemias in childhood are both rare and difficult to diagnose. In such cases timely diagnosis, treatment and prevention tactics should be based on cause-and-effect relation of disease.
