Teaching Guide
Teaching Notes
This case teaches the approach to microcytic anemia with emphasis on distinguishing thalassemia from iron deficiency. Key teaching points: (1) ethnic background is a critical clue for hemoglobinopathies, (2) CBC with peripheral smear is the correct first test, not iron studies alone, (3) hemoglobin electrophoresis is confirmatory, (4) splenomegaly on exam should raise suspicion beyond simple iron deficiency, (5) management of thalassemia intermedia focuses on monitoring and supportive care, not aggressive transfusion.
