Fibrous dysplasia and ossifying fibroma of the paranasal sinuses

Fibro-osseous lesions involving the paranasal sinuses, the mid-face and anterior skull base are uncommon. In addition, there appears to be no clear pathological or clinical classification that embraces the variety of lesions that exhibit such diverse pathological and clinical behaviour, yet may still be referred to as a fibro-osseous lesion. The diagnosis of fibrous dysplasia and ossifying fibroma is made on a combination of clinical, radiological and pathological criteria. This paper emphasizes the clinical and pathological differences between fibrous dysplasia and ossifying fibroma. The more aggressive clinical behaviour of the latter is highlighted and a more radical surgical approach is recommended. In contradistinction, fibrous dysplasia can exhibit a more benign behaviour and radical surgery is not always justified. A clinicopathological distinction between these two conditions is important from a management perspective despite the fact that they both may be encompassed under the 'umbrella' term fibro-osseous lesion.     

Psammomatoid ossifying fibroma]

OBJECTIVE: To clarify the histopathological, clinical behavior biological characterics and the relationship among the psammomatoid ossifying fibroma (POF), ossifying fibroma and fibrous dysplasia of bone. METHODS: Thirty-one cases of POF in the ear and sinonasal region were studied retrospectively. The sections, clinicopathological records from June, 1956 to November, 1996 were reviewed. The reticulum fiber and Masson's stain and alkaline phosphatase immunostain were done in 10 cases, Vimentin, Desmin, EMA and smooth actin immunohistochemical stain were done in 5 cases. One case was studied by transmission electron microscope. RESULTS: The specimens were broken tissue with the sand-like felling, eleven specimens with intact thin shell consisted of bone tissue were used to study the changes in the area between tumor and normal bone. Histopathologically they were rich in mesenchymal tumor cells and a lot of calcifying psammomatoid-like osteoid and a few of calcified bodies similar to those described by Shafer, and the bony trabecula was not found in the center of the tumor. In addition, three zones were noted at the junction of normal bone and tumor, namely, the normal bone-reactive proliferative bone-tumor. In some cases, the reactive bony proliferation may be not marked. The normal bone adjacent to the tumor may be absorbed and disappeared, and were then replaced by the tumor, and finally led to tumor tissue invasion into the soft tissue, but the infiltration appearance is not present. CONCLUSION: POF is the slowly growing benign tumor and is different from ossifying fibroma and fibrous dysplasia of bone.

鼻耳部砂粒性骨化性纤维瘤

目的澄清砂粒性骨化性纤维瘤（ｐｓａｍｍｏｍａｔｏｉｄｏｓｉｆｙｉｎｇｆｉｂｒｏｍａ，ＰＯＦ）的组织学特点、生物学特性、临床行为和骨化性纤维瘤、骨纤维结构不良的关系。方法对我院１９５６年６月～１９９６年１２月４０年期间的３１例ＰＯＦ的组织切片，临床和病理记录资料进行回顾性分析。１０例作网织纤维染色、Ｍａｓｏｎ三色染色（ＭＳ）和碱性磷酸酶免疫酶染色（ＡＰ），５例作波纹蛋白，结蛋白，上皮膜抗体和平滑肌肌动蛋白免疫组化染色。１例作了透射电镜。结果１１例完整标本有薄壁骨壳和大小不等的囊腔，触之有砂粒感。组织学上，肿瘤中心区有丰富的肿瘤性间叶细胞和大量的砂粒骨，无骨小梁。肿瘤和正常骨之间有“三带”（肿瘤反应性骨增生正常骨），反应性骨增生带可不明显，肿瘤附近骨组织有被吸收、消失乃致肿瘤进入软组织的现象，但无恶性浸润的性质。１２例复发。无转移。本瘤好发出血和囊性变。结论鼻耳部ＰＯＦ是生长缓慢的良性肿瘤，是不同于骨化纤维瘤和骨纤维结构不良的独立实体，因为有一定的侵蚀性，可复发，治疗为手术切除。     

Psammomatoid ossifying fibroma

Psammomatoid ossifying fibroma (POF) represents a unique subtype of fibro-osseous lesions. We describe a case of POF involving the orbit and the sinonasal tract, in a 13-year-old white female. Diagnosis depends on the histological, radiological and clinical features. Complete excision by endoscopic nasal surgery was the treatment of choice. Five years later the patient was free from symptoms and tumour recurrence. Differential diagnoses are discussed.     

Aggressive paranasal sinus ossifying fibroma

Sixty-one cases of an aggressive OF involving the paranasal sinus area are reviewed from the literature. We describe another case of this unusual lesion in an 11-year-old girl. These tumors share a similar radiographic appearance, aggressive clinical behavior, and tendency for recurrence after incomplete treatment. Our experiences show that active OF accurately describes this entity and avoids the confusing histologic nomenclature usually encountered. The head and neck surgeon should be aware of this diagnosis so aggressive en bloc resection can be employed whenever possible.     

Endoscopic resection of ossifying fibroma involving paranasal sinuses and the skull base in a series of 15 cases

Conclusion: The key technical challenges in the resection of OFs are rapid removal of tumors by image-guided navigation, determining the boundary of the resection and the proper control of blood supply through the anterior or posterior ethmoidal arteries.

Objective: This study aimed to analyze the clinical data of adult patients with paranasal ossifying fibromas involving the anterior skull base and orbit. The surgical technique and indications are also discussed.

Methods: This study reviewed the clinical data of 15 patients (age >16 years) who underwent resection of paranasal ossifying fibromas involving the anterior skull base and orbit by endoscopic surgery with an image guidance system between October 2006 and October 2014.

Results: The mean age of the 15 patients was 33.2 years (range?=?16–58 years). All tumors were completely resected via endoscopic surgery. Intra-operative cerebrospinal fluid (CSF) leaks (four cases) were repaired endoscopically. The mean follow-up duration was 43.1 months. One patient lost vision after surgery, recurrence was observed in two patients, one underwent a third excision 8 years after the second surgery, and the other exhibited residual osteoarthritis 3 years after the first surgery and remained under regular observation. One patient was lost to follow-up.     

Ultrastructual morphology of juvenile psammomatoid ossifying fibroma

We investigated the ultrastructural morphology of the hard tissue in a fibro-osseous lesion. Bone samples were obtained from a juvenile psammomatoid ossifying fibroma and were observed under a scanning electron microscope. The lesion had a spongy lamellar structure containing bony tissue. On histological examination, resorbing preexisting lamellar bone associated with a large number of cathepsin K-positive osteoclasts was confirmed. Scanning electron microscopy revealed the bony material to have a cribriform structure and to indicate resorption related to osteoclasts throughout the tumor. These characteristic findings revealed the presence of active bony reconstruction and destruction in this lesion. The spongy calcified structure observed by scanning electron microscopy expressed the characteristic ground glass appearance in computed tomography of this patient. This remarkable activation of osteoclasts may deeply relate to characteristic calcified structure in this lesion. Observation of hard tissue structure under a scanning electron microscope may shed light on the pathology of fibro-osseous lesions in the head and neck.     

Juvenile ossifying fibroma. Case report with diagnostic and therapeutic considerations]

BACKGROUND: Fibro-osseous lesions of the jaws, including juvenile ossifying fibroma, pose diagnostic and therapeutic difficulties due to their clinical, radiological and histological variability. CASE REPORT: The case of an 8-year-old girl with a juvenile ossifying fibroma of the mandible is presented. Extirpation of the tumor and filling of the defect with cancellous bone was performed. After 9 months, a recurrence occurred which made a second extirpation of the tumor necessary. This was done without osteoplasty. After a 2-year follow-up the patient is free of tumor. DISCUSSION: Different classifications for fibro-osseous lesions of the jaws can be found in the literature. This makes a correct diagnosis and standardized treatment difficult. Based on the case presented here, the histological features of juvenile ossifying fibroma and the differentiation from osteosarcoma are discussed. At present, conservative surgical treatment seems to be adequate for these tumors.
