Archive Of Standardized Exam Questions: Impetigo


This page is dedicated to organizing various examples of standardized exam questions whose answer is impetigo. While this may seem a odd practice, it is useful to see multiple examples of how impetigo will be characterized on standardized exams (namely the boards and the shelf exams). This page is not meant to be used as a tradition question bank (as all of the answers will be the same), however seeing the classic “test” characterization for a disease is quite valuable.


Question # 1

A 15 year old boy has a facial rash that has persisted for 2 weeks. The rash begins on the chin and has spanned over the rest of his face. A physical exam shows no other remarkable findings. An image of the patient’s face is shown below.


What is the most likely diagnosis?

Question # 2

A 7 year old boy is brought to the clinic because he has had a painful non-itchy rash on his face for the past few days. The patient does not have a fever, chills, or any other symptoms. Past medical history is notable for eczema for which he uses topical petroleum jelly. He is not currently taking any medications and is all caught up with his immunizations. Vital signs are all within normal range. A physical exam reveals erythematous papules, pustules, and a honey-colored crust around his mouth. What is the most likely diagnosis in this patient?

Explanation: honey colored crust rash = impetigo
