[Parapharyngeal nerve tumors (10 recent cases)]
Summary
This study details ten rare tumors, including eight schwannomas and one malignant schwannoma, emphasizing surgical treatment for sub-parotid space tumors.
Area of Science:
- Head and neck oncology
- Surgical pathology
- Neurosurgery
Background:
- Schwannomas, ganglioneuromas, and paragangliomas are rare tumors often found in the head and neck region.
- Distinguishing between anterior and posterior sub-parotid spaces is crucial for diagnosis and treatment planning.
- Surgical intervention is the primary treatment modality for these rare neoplasms.
Observation:
- The study presents ten cases: 8 schwannomas (1 retropharyngeal, 2 anterior sub-parotid including 1 malignant, 2 sympathetic, 3 cranial nerve X), 1 sympathetic ganglioneuroma, and 1 cranial nerve X paraganglioma.
- Detailed histological and anatomical classifications are provided for each case.
- Clinical presentation and anatomopathological features were analyzed.
Findings:
- Malignant schwannoma identified in the anterior sub-parotid space.
- Tumors in the anterior and posterior sub-parotid spaces exhibit distinct clinical and pathological characteristics.
- Successful surgical excision was achieved for all presented cases.
Implications:
- Highlights the importance of precise anatomical and pathological distinctions for accurate diagnosis.
- Underscores the necessity of surgical management for sub-parotid tumors.
- Provides insights into various surgical approaches for treating these rare head and neck tumors.
