You are on call as a local pediatric infectious disease physician and receive a message from a colleague at a nearby primary care clinic. A 10-year-old boy is being referred to you for persistent fever and intermittent dry cough that began 4 weeks ago after a week spent visiting family in Karachi, Pakistan.
A 2-year-old boy presents to the emergency department with a persistent pruritic rash and a 4-week history of enlarging, tender, bilateral anterior and posterior cervical neck masses. The patient is eating and drinking normally, and he is able to breathe comfortably. He has not developed a hoarse voice, excessive drooling, or facial swelling. The family has no pets, history of foreign travel, or exposure to tuberculosis.
A worried mother brings her 2-year-old boy to your office for evaluation of an asymptomatic skin eruption that has been present for 2 months. The lesion developed 6 months after he sustained an abrasion to the same site when he fell on concrete steps.
