AbstractThe authors present a case of a previously healthy 8-year-old girl who presented with pain on the right side of the nose (bony part) radiating to the frontal and temporal regions. Physical examination was normal, whereas magnetic resonance imaging (MRI) of the facial region revealed a tumor limited to the right ethmoidal sinus with a small extension to the medial wall and the upper part of the nasal septum. The tumor was removed by using a 5-degree nasoscope and sent for pathologic examination, which revealed a cemento-ossifying fibroma of the ethmoidal sinus. This is a rare condition, and MRI is a valuable tool in its detection because results of physical examination may be normal in patients reporting nasal pain. According to the World Health Organization classification, this tumor is a variant of cementifying fibromas, which represent a subgroup of cementomas, fibro-osseous lesions containing cementum. Cementifying fibromas are rare tumors. They are usually small, asymptomatic lesions, but although benign, they can develop into aggressive, expansible masses.
