An intraocular solitary fibrous tumor/hemangiopericytoma with extrascleral extension: Case report and review of literature

PURPOSE: To report a case of intraocular solitary fibrous tumor/hemangiopericytoma (SFT/HPC) complicated by extrascleral extension and to review the current literature regarding intraocular SFT/HPC. OBSERVATIONS: A twenty-two year old male presented with decreased vision in his left eye and was found to have a subretinal mass with extrascleral extension. He underwent enucleation of his left eye and histopathology confirmed a diagnosis of SFT/HPC. CONCLUSIONS AND IMPORTANCE: To our knowledge, this is the seventh case of intraocular SFT/HPC ever reported and the first to report extrascleral extension. At the time of publication, there was no evidence of metastases. Extensive clinical, ophthalmic and radiographic imaging, and histopathologic data are presented to contribute to the current understanding of intraocular SFT/HPC.
