Summary
This case study details a rare adenoid cystic carcinoma in the larynx and trachea, showing no recurrence or metastasis four years after surgery. The tumor's unusual location and positive long-term outcome are highlighted.
Area of Science:
- Oncology
- Laryngology
- Surgical Pathology
Background:
- Adenoid cystic carcinoma (ACC) is a rare malignancy that can occur in various head and neck sites.
- Laryngeal ACC, particularly in the subglottic region extending to the trachea, is exceptionally uncommon.
Observation:
- A patient presented with a subglottic laryngeal adenoid cystic carcinoma with tracheal extension.
- The tumor was surgically resected.
- Postoperative follow-up extended to four years.
Findings:
- No local recurrence was observed at the four-year mark.
- No distant metastasis was detected during the follow-up period.
- The case demonstrates an unusual subglottic laryngeal ACC site with a favorable postoperative course.
Implications:
- This case suggests that ACC in this rare location may have a better prognosis than previously thought.
- Further literature review is warranted to understand the behavior of laryngeal ACC.
- Highlights the importance of long-term surveillance for head and neck cancers.
