Pathological Features and Clinical Course in Patients With Recurrent or Malignant Orbital Solitary Fibrous Tumor/Hemangiopericytoma

Abstract

In this cohort of recurrent orbital hemangiopericytoma/SFT, median time to recurrence was 4 years underscoring the importance of careful continued follow-up. The current risk stratification models have limited use for orbital lesions, mostly due to the fact that orbital SFTs are smaller than even the smallest size criteria in this risk assessment model.
