Over the years many amazing cases have been presented during the PEMPix presentation at the American Academy of Pediatrics’ annual national Conference and Exhibition during the Section on Emergency Medicine Sessions.

The Case
A twelve-year old African-American male with no significant past medical history who presents with a two month history of a rash to his right arm. It started at the elbow and progressed up the arm towards the axilla. The patient denied any trauma, new contacts, change in daily routine (soaps, detergents, lotions, etc,.). He had seen his pediatrician on three occasions over the two month period and completed courses of Trimethoprim/Sulfamethoxazole and Cephalexin for a presumed soft tissue infection and a course of topical Clotrimazole with no improvement.
