This page is dedicated to organizing various examples of standardized exam questions whose topic is Langerhans cell histiocytosis. While this may seem a odd practice, it is useful to see multiple examples of how Langerhans cell histiocytosis will be characterized on standardized exams (namely the boards and the shelf exams). This page is not meant to be used as a traditional question bank (as all of the answers will be the same), however seeing the classic “test” characterization for a topic is quite valuable.
KEY CHARACTERISTICS OF THIS CONDITION (ON EXAMS)
When it comes to standardized exams, each topic has its own “code” marked by key buzzwords, lab findings, clues, etc. If you are well versed in this code you will be able to more quickly identify the condition that is being discussed, and get the right answer on the exam you are taking. Below is the “code” for Langerhans cell histiocytosis.
- Lytic bone lesion
- Presence of Birbeck granules on electron microscopy (tennis racket shaped granules)
