Aggressive ossifying fibroma of right ethmoidal sinus: A case report
International Journal of Surgery Case Reports, 2018
BACKGROUND: Ossifying fibroma is a rare benign fibro-osseous lesion seen in the bones of the head and neck area. It is mostly found in the mandible followed by the maxilla and rarely in the paranasal sinuses along with the orbit and skull bones. CASE PRESENTATION: A 30-year-old male patient presented with headache and incidental finding of a right ethmoidal sinus ossifying fibroma by paranasal-sinuses CT scan and MRI of the face. A flexible fiber-optic nasal endoscopy examination revealed a right side fullness. A non-contrasted CT scan of the paranasal sinus showed hyperdense lesion at the right ethmoid air cells. Functional endoscopic sinus surgery was performed and multiple nasal-mass biopsies were taken which showed fibro-osseous lesion most consistent with aggressive ossifying fibroma. Later, a near total resection of skull base tumor by endoscopic surgery was done and patient was discharged next day in a good condition. CONCLUSION: Ossifying fibroma is a rare lesion found in the head and neck area and it is unusual to be found in the paranasal sinuses. Thus crucial attention to the clinical, radiographical and histopathological examination should be taken for more accurate diagnosis and thus appropriate management.
Ossifying Fibroma of the Ethmoid Sinuses: Rare Scenarios
An International Journal Clinical Rhinology, 2011
Ossifying fibroma (OF) is a rare benign tumor, which is a distinct entity, despite being closely related to fibrous dysplasia, according to WHO classification of 2005.1 It is commonly found in mandible and maxilla but rarely found in ethmoid sinuses, orbit and skull base.2-4 It commonly occurs in age group of 20 to 40 years,5,6 although rarely, it can present in all age groups. OF is more common in females than males.4,7 We describe here two cases of OF involving the ethmoid sinuses in young male patients which presented diagnostic dilemmas for us. We report these cases as the site of involvement, age group and sex of patients and diagnostic and management considerations imparted uniqueness to these cases.
Isolated fibrous dysplasia of the ethmoid sinus
SAGE Open Medical Case Reports, 2015
Fibrous dysplasia is a benign fibro-osseous lesion progressing with one or more bone involvements in the skeleton. Even though it is a benign tumor, it may potentially transform into a malignant one. While the most frequently involved zones in the head-neck zone include the maxilla, mandible, parietal, occipital, and temporal zones, the involvement of the ethmoid bone is rather rare. This article presents the case of a female patient who was diagnosed with fibrous dysplasia in the right ethmoid sinus based on the paranasal computerized tomography scan that was taken due to the symptoms of pain around the right eye, pressure, and a feeling of being pushed.
Adenocarcinoma of the Ethmoid sinuses
Acta Neurochirurgica, 1989
New therapeutic modalities for Ethmoidal Adenocarcinomas are presented. Thirty three patients harbouring such a tumour have been treated during the last four years. Twenty three were included in the following protocol: --the first step consisted in inductive chemotherapy based on a four-day course of continuous cisplatine (CDDP) and 5-fluoro-uracyl (5-FU infusion)--the second step was the tumour removal, which was performed through a combined transfacial and subfrontal approach. A contralateral ethmoidectomy was always performed. The integrity of the sphenoidal sinus was systematically checked. The cranial base was reconstructed with madreporic coral grafts; then a large extra-dural pediculated galea flap was placed onto the anterior base to line the sub-frontal dura. The authors discuss the results of this series of rare tumours.

Background: Juvenile ossifying fibromas (JOF) are benign osteofibrous tumors very rarely located in paranasal sinus. The diagnostic and therapeutic tools applied in sinonasal inflammatory pathologies and other tumors fail to address a specific management in this rare pathology. Currently, the only available treatment is surgery. Endoscopic sinus surgery (ESS) allows a complete but minimally invasive approach compared to the open technique, especially for the minor demolition on growing bone structures. Case Description: We describe a case of a 13-year-old boy presenting in the Emergency Department for a head trauma. The computerized tomography (CT) revealed an ethmoid-maxillary bony mass suspected to be a juvenile ossifying fibroma. The patient underwent ESS. Histological examination confirmed a juvenil psammomatoid ossifyng fibroma (JPOF). A revision surgery with the same technique was required after 7 months due to relapse of the tumor. He did not develop postoperative complications. The 3-years followup did not show any signs of relapse. Conclusions: Paranasal JOF is a challenge for the ear-nose-throat (ENT) surgeon. The principles of local disease control for relapse reduction are different from inflammatory diseases and other paranasal tumors. Severe organ damage and recurrences are possible if caution is not observed. Specific guidelines about management are required on the basis of the shared experiences in the few cases reported in literature.
