Giant cell angiofibroma of the orbit and eyelid

Ophthalmology. 1999 Jun;106(6):1223-9. doi: 10.1016/S0161-6420(99)90270-1.

Abstract

Purpose: To report the clinicopathologic features of a newly recognized tumor, giant cell angiofibroma.

Design: Observational case series.

Main outcome measures: Clinical and histopathologic features of giant cell angiofibroma.

Methods: Light and electron microscopy and immunohistochemistry of five cases of giant cell angiofibroma.

Results: A total of five patients (4 women and 1 man) are described: two presented with a painless mass in the eyelid, two with a mass in the orbit, and one presented with a conjunctival lesion. All lesions were well demarcated with no capsule and were composed of blood vessels, a patternless spindle-shaped cell proliferation with a solid and pseudovascular appearance, and multinucleated giant cells. Both spindle-shaped and giant tumor cells were intensely positive for CD34 and vimentin.

Conclusion: Giant cell angiofibroma resembles solitary fibrous tumor and giant cell fibroblastoma and should be considered in the differential diagnosis of spindle-cell tumors in the eyelid, orbit, and conjunctiva.
