A case of primary orbital solitary fibrous tumor with lung metastases 41 years after initial treatment

ABSTRACT

Here, we report a case of an orbital solitary fibrous tumor (SFT) with multiple local recurrences, even after orbital exenteration, and lung metastases after 41 years. The report discusses the clinical and histopathological findings of this case. A 34-year-old female patient with an orbital SFT was treated with orbital exenteration after local resection failed to prevent a recurrence. Ten years later, the patient underwent radiation therapy, followed by two rounds of gamma knife treatment, leading to remission. Forty-one years after the first treatment, the patient, at the age of 75 years, was found to have lung metastases along with orbital recurrence for the eighth time. The patient underwent radiation therapy but died from radiation pneumonitis. Our case emphasizes the need for long-term follow-up of patients with orbital tumors, even after orbital exenteration, to monitor for metastasis.
