A 50 year old male who had frequent infections of his upper respiratory tract manifested with subcutaneous petechiae over his arms and legs. Investigations revealed low haemoglobin and a dry tap marrow. The most likely condition the patient is suffering from

Correct Answer: D

Rationale: Frequent infections, petechiae, low hemoglobin, and a dry tap marrow (no aspirate) indicate aplastic anemia (D), a pancytopenia from bone marrow failure. Iron deficiency (A) causes microcytic anemia without marrow failure, megaloblastic (B) is macrocytic, hemolytic (C) shows high reticulocytes, and thalassemia (E) isn’t pancytopenic—aplastic anemia fits all findings.
