NEW Case: Build a Differential and Make the Diagnosis
A 22-year-old woman visited her doctor about a red rash that developed around her left hand over the past 2 days. The patient was not on any medications and had no prior history of dermatological conditions.
She mentioned that she spent the day prior to rash onset at an Airbnb with some friends celebrating their summer vacation; she spent lots of time outdoors in intense sunlight, neglected to wear sunscreen, and squeezed limes while she prepared margarita drinks. A day later, she experienced a burning sensation in her hand at the location of the rash.
On examination, geometric erythematous plaques with scant scale and a single resolving vesicle with crusting was seen on the dorsal hand and fingers. The patient appeared well and displayed no systemic symptoms.
