Recurrence of Benign Orbital Solitary Fibrous Tumor

Orbital solitary fibrous tumors are rare, accounting for less than 1% of all orbital tumors. These tumors are typically benign and surgical excision is curative, although recurrence of the neoplasm may occur after surgery. We report a case of a recurrent orbital solitary fibrous tumor in a 30-year-old female patient. The patient initially underwent an orbitotomy with partial resection for a right periorbital lesion in April 2024 but presented it to the clinic in September 2024 with worsening right upper eyelid inflammation and a palpable mass. Post-contrast T1-weighted imaging revealed a well-circumscribed enhancing mass in the right superomedial orbit. Right orbitotomy with complete tumor excision was performed, and histopathology of the ovoid nodule confirmed a recurrence of benign solitary fibrous tumor. Orbital solitary fibrous tumors, though rare, should be considered in the differential diagnosis of orbital masses. Complete excision and long-term follow-up are essential in preventing recurrence.
