Discipline Focus: Dermatology is more than just skin deep—rashes and lesions often signal what’s happening systemically.
In this mystery, a seemingly simple rash sends our young detective down a diagnostic rabbit hole. Is it allergic? Infectious? Autoimmune? We’ll explore key patterns in dermatological diagnosis, from distribution and morphology to blanching, scaling, and system red flags. Learn how skin can be the first clue to a hidden illness—and how to distinguish a harmless spot from a signal that something serious is unfolding.
