Summary

A rare second branchial cleft cyst in a 14-year-old boy's pharynx was successfully removed. Histopathology confirmed respiratory-type epithelium lining the cyst, offering insights into branchial cleft anomalies.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Developmental Biology

Background:

  • Branchial cleft anomalies are congenital malformations that can present as cysts, sinuses, or fistulas.
  • The second branchial cleft is the most common origin for these anomalies, typically appearing in the lateral neck.
  • Pharyngeal or oropharyngeal presentation is less common but documented.

Observation:

  • A 14-year-old male presented with a rare pharyngeal cyst.
  • The cyst was situated on the right posterolateral wall of the oropharynx.
  • An intraoral surgical approach was utilized for complete cyst excision.

Findings:

  • Histopathological examination confirmed the cyst originated from the second branchial cleft.
  • The cyst lining was identified as columnar (respiratory type) epithelium.

  • This finding supports the developmental origin from pharyngeal pouch derivatives.

    • Implications:

    • This case highlights the importance of considering branchial cleft anomalies in the differential diagnosis of oropharyngeal masses.
    • The intraoral approach may be a viable and minimally invasive option for select pharyngeal cysts.
    • Understanding the specific epithelial lining aids in confirming the embryological origin and guiding further management.
