Abstract:
Sinonasal glomangiopericytoma is a benign rare tumour of pericytes that accounts for less than 0.5% of all sinonasal tumours. It is an indolent tumour with a macroscopic appearance of common inflammatory polyps. We report the case of a 55-year-old male who presented with right nasal obstruction. CT and MRI examinations demonstrated a soft-tissue mass that obstructed mainly the right nasal cavity. Biopsy revealed glomangiopericytoma. The tumour was treated with preoperative embolisation followed by complete endoscopic resection. Very few cases have been reported to be treated in this way.
Insights
Sinonasal glomangiopericytoma, a rare benign tumor, can mimic inflammatory polyps. This case highlights successful preoperative embolization and endoscopic resection for this unusual sinonasal tumor.
Area of Science:
- Otorhinolaryngology
- Surgical Oncology
- Pathology
Background:
- Sinonasal glomangiopericytoma is an exceptionally rare benign tumor originating from pericytes.
- It constitutes less than 0.5% of all sinonasal tumors and often presents with an indolent clinical course.
- Macroscopically, these tumors can be mistaken for common inflammatory polyps, leading to diagnostic challenges.
