Summary
A rare subglottic thyroglossal duct cyst presented atypically in a 30-year-old male with dysphonia. This case highlights the potential for serious complications from this congenital anomaly.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Congenital Anomalies
Background:
- Thyroglossal duct cysts (TDCs) are common congenital neck anomalies.
- Typically present as midline neck swellings in adults, varying in location.
Observation:
- A 30-year-old male presented with recent onset dysphonia and an unnoticed neck swelling.
- Clinical examination revealed a 2 cm midline cystic lesion.
- Laryngoscopy and CT identified a subglottic, smooth, mucosa-covered cyst.
Findings:
- Surgical excision via laryngofissure was performed with an uneventful recovery.
- Postoperative biopsy confirmed a subglottic thyroglossal duct cyst.
- This subglottic location is exceptionally rare for TDCs.
Implications:
- Highlights the atypical presentation of thyroglossal duct cysts.
- Underscores the potential for life-threatening complications from seemingly innocuous pathology.
- Recommends against fine needle aspiration cytology due to the critical subglottic location.
