title: Rugby injury-associated pseudocyst of the auricle: report and review of sports-associated dermatoses of the ear.
abstract: OBJECTIVE
  To describe a man with pseudocyst of the auricle, summarize the salient features of this condition, and review other sports-associated dermatoses of the ear.
  
  
  BACKGROUND
  Pseudocyst of the auricle is an intracartilaginous collection of viscous straw-colored fluid typically located in the triangular fossa of the upper half of the auricle. It is usually asymptomatic. It can result in a permanent auricular deformity.
  
  
  METHODS
  A 63-year-old man developed a pseudocyst of the auricle following a traumatic rugby-related injury to his left ear. The lesion has persisted for many years; chronic massage has slightly decreased its size.
  
  
  RESULTS
  The etiology of pseudocyst of the auricle has been described as either traumatic or developmental. Our patient developed his pseudocyst after a rugby-related injury. This condition is usually unilateral. Aspirate of the content is usually sterile. Histology shows an intracartilaginous cyst devoid of an epithelial lining. Treatment involves either partial removal of the cartilage or chemical irritation to enhance adhesiveness. Subsequent compression (via button bolsters) minimizes recurrence.
  
  
  CONCLUSIONS
  Pseudocyst of the auricle is a benign cystic dilatation, which is intracartilaginous, devoid of an epithelial lining, and may be traumatic or non-traumatic in origin. A man with rugby-associated trauma to his left ear developed this condition. Auricular pseudocyst can be added to the list of sports-associated dermatoses of the ear.
