Synopsis

Wrestlers and boxers who sustain repeated blunt trauma to the ears can develop subperichondrial hematomas. When blood accumulates between the perichondrium and cartilage, part of or all of the pinna becomes a reddish-purple, shapeless mass. Infection, abscess formation, avascular necrosis, and destruction of the cartilage follow, leading to the development of cauliflower ear, a permanent deformity. Laceration, avulsion, and fracture of the pinna may each contribute to this process as well.

Differential Diagnosis & Pitfalls

  • Keloid(s) on the ear, particularly on the earlobe in people who have had their ears pierced.
  • Relapsing polychondritis – The ear will be uniformly pink or red, and the lobe, which contains no cartilage, will be spared.
  • Weathering nodules of the ears – Can develop in patients with chronic actinic damage.
