A rare sinonasal hemangiopericytoma (HPC) was incidentally diagnosed in a stroke patient. Complete surgical removal and regular follow-up are crucial due to HPC

Area of Science:

  • Oncology
  • Pathology
  • Otorhinolaryngology

Background:

  • Hemangiopericytoma (HPC) is a rare vascular tumor, with only 5% occurring in the sinonasal region.
  • Accurate histological diagnosis of sinonasal HPC can be challenging.

Observation:

  • A 76-year-old female with a history of sinonasal surgery presented with a stroke.
  • Incidental CT findings revealed a paranasal sinus tumor, initially misdiagnosed.
  • Immunocytochemistry confirmed the diagnosis of hemangiopericytoma in this case.

Findings:

  • Sinonasal hemangiopericytoma is characterized by high cellularity, vascularity, and reticular fibers.
  • This rare tumor exhibits a significant potential for recurrence, malignant transformation, and metastasis.

Implications:

  • Complete surgical resection is recommended for sinonasal hemangiopericytoma.
  • Regular short-term follow-up is advisable to monitor for recurrence.
