OBJECTIVE AND IMPORTANCE: @entity2460 ( @entity2460 ) are rare @entity5 of mesenchymal origin that typically arise in the pleura. Only 24 cases of @entity2460 in the orbit have been reported, all located within the orbit and generally with a benign course. We report the first case of an orbital SFT with extraorbital extension and short-term regrowth. CLINICAL PRESENTATION: A 54-year-old @entity1 presented with proptosis and @entity892 that had persisted for 7 months. The @entity5 extended from the right extraconal inferolateral orbit to the extradural middle cranial fossa and cavernous sinus, via the superior orbital fissure, on magnetic resonance imaging scans. Positron emission tomography with @entity419 demonstrated faint uptake in the orbital portion. INTERVENTION: Resection of the @entity5 was performed twice, because of short-term regrowth of the @entity41 in the orbit. The histological diagnosis was a SFT. The @entity1758 labeling index was 7% and the mitotic count was 5 mitotic figures/10 high-power fields at the time of the second operation. These findings indicate the malignant nature of the @entity5 . CONCLUSION: The natural history of @entity2460 of the orbit remains unclear, and the importance of careful and continued follow-up monitoring of the @entity5 should be emphasized.
