Zenker's diverticulum
Zenker's diverticulum is an outpouching of the mucosa and submucosa at the junction of the pharynx and esophagus.
It is also known as cricopharyngeal diverticulum, pharyngoesophageal diverticulum and hypopharyngeal diverticulum.[1]

- Benign.
- A malignancy (squamous cell carcinoma) may arise from it;[2][3] seen in ~0.3% of cases.[4]
- Relatively uncommon[5] - but most common among esophageal diverticula.[6]
