Orbital solitary fibrous tumor: encompassing terminology for hemangiopericytoma, giant cell angiofibroma, and fibrous histiocytoma of the orbit: reappraisal of 41 cases
“…1,2 Orbital solitary fibrous tumor was first recognized in 1994, and its histopathology has since been well-described. 1,[3][4][5][6] SFT demonstrates great variability in its morphology and shares histologic features with other benign mesenchymal tumors of this area such as schwannoma and hemangiopericytoma.…”
BACKGROUND AND PURPOSE:Orbital SFT is a rare tumor, often misdiagnosed as orbital schwannoma preoperatively but with different prognosis and treatment. Our aim was to evaluate MR imaging features that might distinguish orbital SFT from schwannoma.
“…Recently, 41 cases of fibroblastic orbital tumors which were originally diagnosed as hemangiopericytoma (n=16), fibrous histiocytoma (n=9), mixed tumors (n=14) and giant cell angiofibroma (n=2), have been reclassified in a new spectrum under the encompassing terminology of orbital SFT. 5 In conclusion, SFT should be kept in mind in the differential diagnosis of a well-defined orbital mass with an indolent clinical course. Strong CD34 staining is the most prominent diagnostic feature of SFT.…”

“…CD34 immunopositive fibroblastic neoplasms, which were previously classified as separate entities, are now comprised as SFT. 5 In this case report, we present a case of an orbital SFT treated with complete surgical excision. …”
