Tracheal squamous cell carcinoma treated endoscopically.

Malignant primary tracheal tumors are extremely rare. The most common malignant primary tracheal tumors are squamous cell carcinoma and adenoid cystic carcinomas. In this brief report, we describe a patient who presented with a primary papillary squamous cell carcinoma in-situ at multiple areas in the trachea with a significant airway obstruction. Our case was successfully managed using a combination of electrocautery and argon photocoagulation for endotracheal ablation of the tumor and adjuvant external beam radiotherapy.
