Write answer in between .Q:A 7-year-old girl presents to a new pediatrician with fever, shortness of breath, and productive cough. She had similar symptoms a few weeks ago. The girl was born at 39 weeks gestation via spontaneous vaginal delivery. She is up to date on all vaccines and is meeting all developmental milestones. A further review of her history reveals seizures, upper respiratory infections, and cellulitis. On physical examination, the patient is pale with white-blonde hair and pale blue eyes. Which of the following would you expect to see on a peripheral blood smear for this patient?? A: Predominance of band leukocytes, B: Stippled eosinophils, C: Downey cells, D: Polymorphonuclear leukocytes containing giant inclusion bodies, E: Significant basophil predominance,  <response>: This is a clinical vignette about a 7-year-old girl with recurrent fever, respiratory symptoms, and a history of seizures, infections, and developmental delay. She has physical exam findings of pale skin, hair, and eyes. The question asks about expected peripheral blood smear findings in this patient. Based on the clinical history and physical exam findings, this patient likely has Chediak-Higashi syndrome. This is a rare autosomal recessive disorder characterized by immunodeficiency, partial albinism, bleeding tendency, and neurologic manifestations. On peripheral blood smear, patients with Chediak-Higashi syndrome typically demonstrate giant inclusion bodies within polymorphonuclear leukocytes and monocytes. Therefore, the correct answer is likely choice D.Choices A, B, C, and E describe peripheral blood smear findings seen in other conditions and are incorrect in this clinical scenario.D: Polymorphonuclear leukocytes containing giant inclusion bodies
