[Cemento-ossifying fibroma of the sphenoethmoidal sinus [case report]]

ABSTRACT

Cemento-Ossifying Fibroma [COF] is a well-demarcated and occasionally encapsulated neoplasm that contains fibrous tissue and varyig amounts of calcified tissue resembling bone, cementom, or both. We report a case of COF involving the ethmoid and sphenoid sinuses and review the literature in order to study the clinical features, imaging findings and histopathologic characteristics of COF. A 19-year-old women was referred to our hospital because of headache and 4 millimeter proptosis in the left eye of one year's ago. A clinical examination revealed a red mass in the middle meatus of the left nose. C.T scan showed a large lobulated lytic lesion in the ethmoid and sphenoid sinuses. The patient was operated with endoscopic sinus surgery three time. The first histologic report was mucopyocells of ethmoid and sphenoid sinuses but second histologic report was cemento-ossifying fibroma. A Combined study in cooperating clinical radiographic and pathologic findings is important in order to ensure a accurate diagnosis. Postoperative follow up is essential; especially in cases where incomplete removal of the COF was performed
