 Cutaneous findings are sometimes the first clue to a life-threatening disorder. Practitioners are not always cognizant of the diseases associated with the cutaneous findings and proper diagnosis may be delayed. Objective

 This presentation will highlight the cutaneous findings in staphylococcal scalded syndrome , , meningococcemia, RMSF, Steven’s Johnson Syndrome and . Recognition of the findings will allow for prompt diagnosis . Expected Outcome

 The attendees should be able to recognize skin changes in these disorders and appropriately recommend further work-up and treatment following this session. Patient outcomes will be improved through the acquisition of this knowledge. STAPHYLOCOCCAL SCALDED SKIN SYNDROME
