Summary
This case report details a rare laryngeal choristoma, specifically heterotopic salivary gland tissue, found in an 80-year-old male. Surgical resection was successful, highlighting a unique cause of laryngeal masses.
Area of Science:
- Otolaryngology
- Pathology
Background:
- Laryngeal choristomas are rare, typically involving thyroid or glial tissue.
- Salivary gland tissue as a laryngeal choristoma has not been previously reported.
Observation:
- An 80-year-old male presented with hoarseness and productive cough.
- A left-sided laryngeal tumorous swelling was observed with preserved vocal cord mobility.
Findings:
- Microlaryngoscopic resection of the mass was performed without complications.
- Histological examination confirmed the mass as a choristoma composed of heterotopic salivary gland tissue within muscle and fat.
- No signs of malignancy were detected, and the overlying mucosa was intact.
Implications:
- This case expands the differential diagnosis for laryngeal masses to include salivary gland choristomas.
- Accurate histological diagnosis is crucial for differentiating these rare benign lesions from malignant tumors and other conditions.
- Intralaryngeal resection is presented as the recommended treatment for such laryngeal choristomas.
