Summary
This study reports an extremely rare case of a soft tissue chondroma in the buccal mucosa. This benign tumor, typically found in extremities, highlights the importance of considering rare oral cavity lesions.
Area of Science:
- Oral pathology
- Benign soft tissue tumors
- Histopathology
Background:
- Soft tissue chondromas are rare, benign neoplasms distinct from bone.
- They predominantly occur in the distal extremities.
- Chondromas of the oral cavity are exceptionally uncommon, with few documented cases, primarily in the tongue.
Observation:
- A case of a chondroma originating in the buccal mucosa is presented.
- The lesion presented as a lobulated mass with myxoid tissue and central chondroid differentiation.
- Immunocytochemistry confirmed a mesenchymal, not epithelial, origin.
Findings:
- The buccal mucosa chondroma demonstrated characteristic chondroid differentiation.
- Immunohistochemical analysis supported a mesenchymal origin for the tumor.
- Histological features were consistent with a benign chondromatous neoplasm.
Implications:
- This case expands the known locations for soft tissue chondromas.
- Accurate diagnosis is crucial to differentiate from other chondroid lesions and malignancies.
- Highlights the need for awareness of rare oral soft tissue tumors in clinical practice.
