Thoracic Oesophageal Cancer As a Cause of Stridor: a Literature Review.

An 83-year-old woman, with a background of treated squamous cell oesophageal cancer, presented with a 3-week history of stridor. Of note, the patient had no risk factors for oesophageal cancer other than age. Clinical examination was unremarkable apart from stridor. Laboratory investigations, including arterial blood gas on room air, were unremarkable. Radiological examination revealed a 4.5×3.5×3.6 cm mass involving the posterior trachea and invading the tracheal orifice. Oesophagogastroduodenoscopy and rigid bronchoscopy confirmed an extensive tumour arising from the lower oesophagus and invading the trachea, causing 90% airway obstruction for a 6 mm length ending 1.5 cm above the carina. Biopsy revealed a poorly differentiated carcinoma with foci of squamous cell carcinoma. Unfortunately, the patient passed away 2 months after palliative tracheal stent placement.
