Summary
This case report details an unusual osseous choristoma, a benign bony tumor, found in the submandibular region. This rare oral cavity lesion highlights the need for long-term monitoring post-excision.
Area of Science:
- Oral pathology
- Head and neck surgery
- Histopathology
Background:
- Osseous choristoma is a rare benign oral lesion, typically presenting as a bony mass in an abnormal location.
- These lesions are most commonly found on the tongue, making submandibular occurrences exceptionally uncommon.
Observation:
- A 32-year-old male presented with a submandibular lesion.
- The lesion was surgically excised.
- No recurrence was observed during a 28-month follow-up period.
Findings:
- This case represents the first documented instance of an osseous choristoma in the submandibular region.
- Histopathological examination confirmed the benign nature of the lesion, characterized by mature bone tissue.
Implications:
- The findings suggest that osseous choristomas, while benign, may occur in rare anatomical locations within the oral cavity.
- Extended clinical and radiographic follow-up is crucial after surgical management to ensure no recurrence, even for histologically benign lesions.
