Orbital solitary fibrous tumor. Another rare case from Africa.

ABSTRACT

Solitary fibrous tumor (SFT) of the orbit, initially thought to be rare, is being increasingly documented in the medical literature. We here present the case of a 37-year-old Nigerian man who presented with left sided painless, vision-sparing proptosis. Cranial computed tomography scan showed a globular, left medial, orbital extraconal mass. The mass was excised, en bloc, via a medial orbitotomy procedure aided by left ethmoidectomy. Surgery was uncomplicated and histology of the excised tissue was reported as compatible with SFT. There was also a strong and diffuse immunostaining with CD 34. At 6-month follow-up, the left-sided proptosis has completely regressed. To the best of our knowledge, this is the second case of orbital SFT to be reported in an African.
