case_images: (a) Axial and (b) coronal MR scan demonstrating a well-circumscribed mass of relatively homogeneous consistency in intraconal region of the right eye. (c) Intraoperative identification of giant cell angiofibroma. (d) Postoperative appearance of the mass after total excision. (e) Patternless giant cell (white arrow) and spindle cell (black arrow) proliferation (Hematoxylin-eosin, x100). (f) Diffuse CD34 positivity in tumor cells (Diaminobenzidine, x100)

case_images: T1 signal and hyperintense in T2 signal [Fig. 1a and b]. There was no sign of bone erosion or infiltration to adjacent soft tissues. Then, the tumor was freed up entirely with blunt dissection and removed in total [Fig. 1c]. Macroscopically, the tumor was ovoid, highly vascular, white-gray with smooth borders [Fig. 1d]. Floret-like multinucleated giant cells often lined the pseudovascular spaces [Fig. 1e]. Immunohistochemistry was performed; spindle cells as well as the giant cells showed reactivity for Vimentin, CD34, and bcl-2 [Fig. 1f].
