Hemangiopericytoma is an uncommon mesenchymal tumor originating from pericy
tes. We describe the clinical and morphologic features in a case of intrath
oracic extrapulmonary giant hemangiopericytoma. The tumor was radically rem
oved, and the microscopy report was benign hemangiopericytoma. Because of t
he high risk of local recurrence, long-term follow-up is important in such
patients.
