Summary

Relapsing polychondritis (RPC) can affect the airways, causing life-threatening stenosis. Early diagnosis and treatment with steroids and T-tube intubation can lead to recovery.

Area of Science:

  • Medicine
  • Immunology
  • Otolaryngology

Background:

  • Relapsing polychondritis (RPC) is a rare multisystemic disorder characterized by progressive cartilage destruction.
  • Respiratory tract involvement, particularly laryngeal and tracheal stenosis, poses a significant threat to patient survival.

Observation:

  • A patient presented with sudden respiratory arrest due to severe subglottic tracheal and left main bronchus stenosis.
  • Initial clinical presentation lacked typical RPC features, complicating the diagnosis.
  • CT imaging revealed characteristic "worm-eaten" like mucosal thickening of the trachea.

Findings:

  • Tracheal and thyroid cartilage biopsy demonstrated chondral degeneration and inflammatory cell infiltration, consistent with RPC.
  • The patient was diagnosed with relapsing polychondritis based on these findings.

Implications:

  • Prompt diagnosis and management, including Montgomery T-tube intubation and systemic steroids, are crucial for improving outcomes in RPC patients with airway compromise.
  • This case highlights the importance of considering RPC in patients with unexplained airway stenosis, even with atypical presentations.
  • Long-term monitoring is essential as airway narrowing may not progress with appropriate treatment.
