Abstract

The ductal cyst of the hypopharynx is a very rare tumor. We report a case of hypopharyngeal ductal cyst in a 63-year-old man presenting with globus sensation. It was removed by a laryngomicrosurgical technique, using a microdissection electrode. Masses of the hypopharynx may not always be easily visible on routine examination of the hypopharynx with flexible fiberoptic laryngoscopes. Particularly in cases of benign tumors, the diagnosis may be delayed due to a prolonged history of mild and subtle symptoms. We missed the hypopharyngeal mass at the initial presentation, but could detect the mass in the pyriform sinus with a double contrast barium swallow study. We describe the diagnostic method to detect hypopharyngeal tumors and the treatment of benign hypopharyngeal masses.

  Fig. 1 (A) Frontal view from a double-contrast pharyngoesophagogram shows a large contour defect (arrowhead) in the left pyrifrom sinus. (B, C) The axial and coronal contrast-enhanced computed tomography scans show a well-circumscribed, hypodense lesion (arrow) in the left pyriform sinus of the hypopharynx.

• 

  Fig. 2 (A) The surgical specimen was myxoid and well-encapsulated, measuring 2×3×4 cm. (B) Microscopic examination revealed that the cyst wall was lined by cuboidal epithelial cells and had loose connective tissue in the stroma (H&E, ×200).
