FBC or CBC Findings-

Severe microcytic, hypochromic anaemia with low ferritin but A has thrombocytopenia but B has thrombocytosis.

Differential Diagnoses:

• A rare theoretical scenario where an iron-deficient patient develops immune thrombocytopenic purpura (ITP). Although possible in theory, it is not commonly encountered.

• Evans syndrome, an autoimmune condition involving multiple cytopenias, which is worth reading about and understanding.

Final Diagnosis- Iron Deficiency Anaemia.

Typically, iron deficiency anaemia presents with a high platelet count. However, on rare occasions, it can be associated with a low platelet count. Importantly, even in cases where platelet counts are low, bleeding has not been reported in patients with iron deficiency anaemia.

Both this children responded very well to treatment, and within a few weeks, their haemoglobin levels showed clear improvement. Based on the clinical picture and response to therapy, no further investigations were required.

Message - Iron Deficiency commonly has Thrombocytosis but uncommonly it can have significant Thrombocytopenia.
