A case study details a 43-year-old man with progressive ear hypertrophy. Elevated anti-collagen II antibodies suggest an autoimmune link to this rare condition.

Area of Science:

  • Dermatology
  • Immunology
  • Otolaryngology

Background:

  • Progressive bilateral ear hypertrophy is a rare condition.
  • Previous treatments with topical steroids and antimicrobials were ineffective.

Observation:

  • A 43-year-old man presented with a 5-month history of ear hypertrophy, erythema, and swelling.
  • Symptoms included decreased hearing due to external auditory canal narrowing and occasional pruritus.
  • Physical examination revealed firm ear hypertrophy, sparing earlobes, with no pain on palpation.

Findings:

  • Histologic examination showed dermal lymphocytic and plasma cell infiltrate with subcutaneous fibrosis.
  • Blood tests revealed elevated anti-collagen II antibodies (29.2 Eu/ml).
  • Complete blood count, antinuclear antibody, and rheumatoid factor were within normal limits.

Implications:

  • Elevated anti-collagen II antibodies may indicate an autoimmune etiology for ear hypertrophy.
  • This case highlights the importance of considering autoimmune markers in unexplained ear conditions.
  • Further research is needed to understand the pathogenesis and treatment of collagen-induced ear hypertrophy.
