The Mysterious Case of a Lumpy Newborn
Can you identify this acute widespread nodular rash on a neonate who is otherwise ready for discharge?
An otherwise healthy 2-week-old infant is ready for discharge but that morning is found to have an alarming widespread, violaceous rash. Dr Jon Schneider was ready to head home late that same day when a former resident called and appealed to his keen interest in dermatology.Head to the opposite side of the university hospital with him and see the child as the resident, now in the nursery, fills you in on the perinatal particulars. What's in your differential Dx? Please avoid scrolling down for references until you've finished reading the case.       Â
