Hemangiopericitoma de órbita

Abstract: Hemangiopericytomas are rare tumors arising from the proliferation of pericytes. They may be found in the lungs, bones, skull, deep soft tissue or limbs. The tumor has an unpredictable prognosis and when it affects the orbital region, may have an aggressive behavior, with high incidence of recurrence. We report a case of orbital hemangiopericytoma and highlight clinical, surgical, and histopathological features of these tumors. Orbital hemangiopericytomas usually are solid, slow-growing tumors.
