Introduction

• Very rare.
• Cause: various tumor types.
• Signs: upper airway obstruction, inspiratory stridor.
• Diagnosis: signs, radiography, endoscopy.
• Treatment: surgery or chemotherapy.
• Prognosis: poor.

Pathogenesis

Etiology

• Laryngeal neoplasms very rare:
  • SCC.
  • Leiomyoma.
  • Rhabdomyosarcoma.
  • Oncocytoma.
  • Mast cell tumor.
  • Chondrosarcoma.
  • Adenocarcinoma.
  • Lymphoma.
  • Melanoma.
  • Benign neoplasm.
• Perilaryngeal tumors are more common, eg thyroid carcinoma Thyroid gland: neoplasia , lymphoma Lymphoma - and may interfere with laryngeal function.

Pathophysiology

• Laryngeal or extralaryngeal neoplasia → upper airway obstruction.
• Interference with swallowing → dysphagia/aspiration pneumonia.

Timecourse

• Depends on nature and location of tumor.
