[Malignant peripheral nerve sheath tumor in the maxillary sinus: a case report]
Summary
Malignant peripheral nerve sheath tumors (MPNST) in the maxillary sinus are rare but aggressive. Surgical resection offers a better prognosis than radiotherapy or chemotherapy for these nasal cavity tumors.
Area of Science:
- Oncology
- Surgical Pathology
- Head and Neck Surgery
Background:
- Malignant peripheral nerve sheath tumors (MPNST) are rare, aggressive neoplasms arising from peripheral nerves.
- MPNSTs in the nasal cavity and paranasal sinuses are uncommon, often presenting with poor prognoses.
Observation:
- A case study of a 46-year-old woman with xanthoderma diagnosed with malignant peripheral nerve sheath tumor of the right maxillary sinus.
- Histological confirmation of the tumor was obtained.
- The patient underwent a right total maxillectomy and adjuvant radiotherapy.
Findings:
- The patient experienced no local recurrence or metastasis one year post-treatment.
- Literature review indicates that MPNST in the nasal cavity and paranasal sinuses have a poor prognosis, with local recurrence and metastasis being the primary causes of mortality.
Implications:
- Surgical resection appears to be more advantageous than adjuvant radiotherapy and chemotherapy for managing sinonasal MPNST.
- Early diagnosis and aggressive surgical management are crucial for improving outcomes in these rare malignancies.
