OBJECTIVE: Solitary fibrous tumor (SFT) is a spindle cell neoplasm that rarely occurs in orbit. This study aimed to report the clinical, imaging, and pathological features of three patients with recurrent orbital SFTs.
METHODS: Clinical, imaging, and pathological data of the three patients were retrospectively reviewed, and the results were compared with those of previously reported cases with recurrent orbital SFT.
RESULTS: One female and two male patients (mean age, 54 years old) were included in this study. The present cases and literature review showed that the average time to recurrence in patients who aged under 50 years old was shorter than that in those who aged over 50 years old. The most common site for recurrent orbital SFT was the retrobulbar area of the orbit (23.8%). Imaging examinations showed consistent intensity of MRI signals before and after recurrence. Immunohistochemical results of all cases revealed the expressions of CD34. The mitotic rate increased in 4/8 cases, and the percentage of Ki-67-positive cells was elevated in 5/16 cases.
CONCLUSION: These results suggested that young patients were more likely subjected to recurrent orbital SFT. The postoperative pathological diagnosis revealed that patients with recurrent orbital SFT had more nuclear abnormalities and mitotic activity, as well as a higher percentage of Ki-67-positive cells, indicating that orbital recurrent SFT tended to be malignant according to both morphological features and immunohistochemistry results.
