title: Benign fibrous histiocytoma associated with a frontoethmoidal mucopyocele and orbital abscess.
abstract: A 74-year-old man sought treatment for painful swelling in the right upper eyelid. CT demonstrated a frontoethmoidal mucocele extending in the right orbit with abscess formation. Following functional endoscopic sinus surgery, the inflammatory symptoms in the right eye nearly resolved. However, a firm mass was still noted in the same location. Histopathologic examination proved it to be a benign fibrous histiocytoma. Benign fibrous histiocytoma may occur in association with an orbital abscess secondary to mucocele.
