Abstract
Pharyngoesophageal diverticulum is a rare clinical entity and can be broadly classified into 3 main types based on anatomical protrusion. Zenker diverticulum (ZD) represents the most common pharyngoesophageal diverticulum, followed by Killian-Jamieson diverticulum (KJD) and lastly Laimer diverticulum. These anatomical anomalities are generally thought to be benign and there is no reported literature on its potential for malignant transformation.
We present a case of Killian-Jamieson diverticulum which was surgically excised via transcervical approach. Histopathology of the diverticulum revealed squamous cell dysplasia. To the author's best knowledge, this is the first case report of a pharyngoesophageal diverticulum that showed malignant potential.
