Summary
Sinonasal hemangiopericytoma (SNHPC) is a rare, low-grade malignant vascular tumor. Diagnosis requires histology and immunohistochemistry, with surgery as the primary treatment, often via endoscopic techniques for localized cases.
Area of Science:
- Oncology
- Otorhinolaryngology
- Pathology
Background:
- Sinonasal hemangiopericytoma (SNHPC) is a rare vascular tumor with a specific clinical behavior.
- Intra-nasal location of SNHPC is exceptionally uncommon.
Observation:
- A case of SNHPC in a 47-year-old male involving the left nasal cavity was treated with endoscopic sinus surgery.
- The tumor exhibited characteristic clinical, histological, and radiological features.
Findings:
- Diagnosis is confirmed by histological and immunohistochemical studies, with positive Vimentin (98%) and SMA (92%) markers.
- MRI and CT scans are crucial for assessing tumor extent; angiography aids in evaluating vascularization.
- Complete surgical excision with tumor-free margins is the gold standard treatment.
Implications:
- Endoscopic surgery is feasible for SNHPC without extra-nasal extension.
- Radiotherapy is recommended for cases with positive or suspicious margins.
- Lifelong endoscopic surveillance is necessary due to the potential for late recurrences, which are managed surgically.
