title: The Utility of Assessing Neck Acne.
abstract: BACKGROUND
  Acne grading is an essential component in establishing treatment options, but little is known on how neck acne should be incorporated into grading scales.
  
  
  OBJECTIVE
  Our objective was to explore the prevalence of neck acne and determine if its own severity category on an acne global grading scale was warranted.
  
  
  METHODS
  Acne severity was assessed in 6 categories: face, chest, back, anterior upper (AUN), anterior lower neck (ALN), and posterior neck (PN).
  
  
  RESULTS
  The overall prevalence of neck acne was 49%. Of these, 44% had AUN acne, 18.5% had ALN acne, and 19.8% had PN acne. AUN and facial acne had a significant correlation ( r = 0.37, P < .05). No correlation was seen amongst other areas. Males presented with a significantly higher severity of AUN (mean [SD], 1.37 [1.09]) than females (mean [SD], 0.52 [0.91]), on average.
  
  
  CONCLUSIONS
  While neck acne has proven to be common amongst those with acne on other areas of the body, facial acne can be used as a proxy for classification, as neck severity is usually milder.
