Recurrent Sinonasal Hemangiopericytoma: A Rare Case Report

摘要

Hemangiopericytoma (HPC) is a rare vascular tumor arising from capillary pericytes. This tumor represents 3% - 5% of all soft tissue sarcomas and 1% of all vascular tumors. Only 15% - 30% of cases occur in the head and neck region, among which sinonasal hemangiopericytoma (HPC) is accounted for around 5% of cases. Hemangiopericytoma (HPC) has a tendency for recurrence. Here, a case of recurrent nasal hemangiopericytoma (HPC) after 12 years of treatment is reported.
