Research background

Solitary fibrous tumor (SFT) is predominant within the pleura but very rare in the orbit, which is why the diagnosis of orbital SFT poses challenges in clinical practice.

Research motivation

Unspecific symptoms and a wide range of clinical manifestations of SFT can significantly hamper the establishment of a definitive diagnosis and treatment.

Research objectives

To retrospectively explore the clinical and imaging characteristics, treatment, outcomes of a series of patients with orbital SFT.

Research methods

This is a retrospective analysis of patients diagnosed with a histopathologic orbital SFT treated at a single institution. All data on demographics, clinical characteristics, imaging, treatment, postoperative histopathological and immunohistochemical (IHC) examinations, and prognosis were collected.

Research results

In total, 13 patients were enrolled, 7 (53.8%) of whom had the tumors located in the superomedial quadrant of the orbit. Notably, 12 (92.3%) patients showed significant enhancement, whereas there were patchy slightly enhanced areas in the tumor. IHC analysis demonstrated that the tumor cells were immunoreactive for CD34, CD99, STAT-6, and vimentin in all patients. The lesions showed Ki-67 positivity < 5% in 1 (7.7) patient, 5%-10% in 10 (76.9%), and > 10% in 2 (15.4%). Two (15.4%) patients exhibited tumor recurrence.

Research conclusions

The clinical manifestations and radiologic characteristics of orbital SFT are diverse and not specific. Accurate diagnosis and treatment require detailed radiological and histopathological/IHC evaluation.

Research perspectives

A more comprehensive analysis of the clinical symptoms, therapeutic efficacy, and prognosis of orbital SFT should be performed in the future.
