Summary
Oncocytomas in the upper jaw are rare and often malignant. Radical surgical excision is the recommended treatment for these aggressive tumors.
Area of Science:
- Oncology
- Head and Neck Surgery
- Pathology
Background:
- Oncocytomas are uncommon tumors, typically benign in the parotid gland.
- Their occurrence in the upper jaw is rare, with limited literature reviews.
- Malignant potential outside major salivary glands is suggested, potentially as low-grade adenocarcinomas.
Observation:
- A case of a malignant oncocytoma in the lateral nasal wall of a 78-year-old female is presented.
- A comprehensive literature search identified 19 cases of upper jaw oncocytomas.
- The reviewed cases showed a wide age distribution (10 male, 9 female).
Findings:
- Thirteen of the 19 upper jaw oncocytomas were malignant.
- Three of the malignant cases presented with metastases.
- Malignancy is a significant concern for oncocytomas in this anatomical location.
Implications:
- Oncocytomas of the upper jaw should be presumed malignant.
- Radical surgical excision is the primary treatment modality.
- Further research into the behavior and management of upper jaw oncocytomas is warranted.
