Summary
This case report details the first instance of squamous cell carcinoma found in a recurrent pharyngeal pouch after endoscopic stapling. This highlights a rare risk associated with this treatment for pharyngeal diverticula.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Otolaryngology
Background:
- Pharyngeal pouches (Zenker's diverticula) are treated endoscopically.
- Endoscopic stapling is a common method for pharyngeal pouch repair.
- Recurrence after endoscopic stapling can occur.
Observation:
- A patient presented with a recurrent pharyngeal pouch post-endoscopic stapling.
- Imaging confirmed the recurrent diverticulum.
- Endoscopic examination revealed a tumor within the pouch.
Findings:
- Histopathology confirmed the tumor as squamous cell carcinoma.
- This represents the first reported case of carcinoma in a pharyngeal pouch treated with endoscopic stapling.
- The patient underwent surgical excision and radiotherapy.
Implications:
- Endoscopic stapling for pharyngeal diverticula carries a rare risk of malignancy.
- Surveillance may be warranted for patients with recurrent pouches after this procedure.
- This finding necessitates awareness among clinicians regarding potential long-term complications.
