Review
The aim was to compare clinical and radiological features of the two juvenile ossifying fibroma (JOF) variants, trabecular (JTOF) and juvenile psammomatoid ossifying fibroma (JPOF). An electronic search was undertaken in March 2019. Eligibility criteria included publications having sufficient clinical, radiological, and histological information to confirm the diagnosis. A total of 185 publications and 491 cases were included. Most JOFs, including both variants, showed bone expansion, were painless, presented no cortical perforation and no secondary aneurysmal bone cyst, did not cause tooth root resorption, and had a mixed unilocular radiodensity appearance and well-defined limits on radiological examination. Patients with JPOF were on average older than those with JTOF. Enucleation and curettage was associated with a considerably high recurrence rate, regardless of the anatomical location or variant type of the lesion. Enucleation followed by either curettage or peripheral osteotomy showed lower recurrence rates than enucleation only. When resection was performed, only one case of JTOF presented recurrence. In conclusion, JOF lesions presented high rates of recurrence after treatment by curettage and enucleation only. Although surgical resection of JOFs resulted in the virtual absence of recurrence, enucleation followed by peripheral osteotomy/curettage should be the treatment of choice for both JOF variants to avoid the disfigurement usually associated with surgical resection.

Review
OBJECTIVE
The aim of this study is to evaluate recent evidence-based data that summarize the clinicopathological findings and treatment along with follow-up measures taken in terms of published cases of Juvenile psammomatoid ossifying fibroma (JPOF) of the maxilla and mandible by a systematic review. MATERIALS AND METHODS: The databases searched were PubMed, MEDLINE, Scopus, Google scholar, and Cross references. Only those case reports of JPOFs published in the English language from 2000 to 2022 were considered. All cases included confirmed JPOF lesions histopathologically. The SR-included details like clinical and radiographic data, follow-up details such as recurrence, and the presence of any adverse outcome.
RESULTS
The database search produced 595 articles from 2000 to 2022, among which 22 case reports were included in the systematic review. The mean age of JPOF occurrence in patients was 18 ± 16 years. A male predilection was noted among patients younger than 14 years of age, whereas a female predilection was noted in patients older than 14 years of age. Frequent involvement of the mandible (56%) compared to the maxilla (44%) was reported. The posterior mandible was the most commonly affected site involving numerous adjacent structures. The expansile nature of the JPOF displayed 57% buccolingual expansion, 50% downward displacement or erosion of the lower border of the mandible and 81% of involvement of the maxillary antrum/pterygoid plate/orbital floor. Among the 20 cases reported, the treatment provided included surgical excision in 45% of the patients, jaw resection in 35% of the patients, and enucleation and curettage in 18% of the patients. Follow-up details were provided in 80% of the reports that showed recurrence.
CONCLUSIONS
The diagnosis of JPOF requires correlation of the clinical and radiographic features with key histopathological features. Although long-term follow-up of the case reports has been reported, the data lack information about the long-term outcomes of JPOF.

Review
BACKGROUND
The purpose of this work was to perform a systematic review regarding ossifying fibroma and its multiple variants of the paranasal sinuses, and to identify any clinical differences between the multiple variants.
METHODS
A search of the U.S. National Library of Medicine (PubMed) database was performed for the non–Medical Subject Heading (MeSH) search term “ossifying fibroma.” The bibliographies of the retrieved manuscripts were searched to identify additional potentially relevant articles. Finally, textbooks of head and neck pathology were searched to identify peer-reviewed literature that addresses the histopathology of ossifying fibroma and its variants. Abstracts were screened by 2 of the authors to identify reports of ossifying fibroma lesions (and its variants) that involved the paranasal sinuses. Extracted data from case reports or case series included the clinical presentation, age, gender, site of involvement, surgical approach, treatment outcome, follow-up period, and recurrence rate. Information derived from cases is summarized in tables, and simple descriptive statistics were applied to the data.
RESULTS
A total of 137 distinct patients were identified in 103 reports. Extracted data did not show any appreciable difference in clinical presentation or outcomes. Data on recurrence of these lesions was often limited by a lack of follow-up.
CONCLUSION
Although differentiation between the subtypes of ossifying fibroma can be made histologically, and a diverse nomenclature exists, there does not appear to be any overriding clinical significance to the histopathologic differentiation of OF variants.

Comparative Study Review
OBJECTIVES
The aim was to evaluate the principal features of ossifying fibroma (OF) by systematic review (SR), and to compare their frequencies among four global groups.
METHODS
The databases searched were the PubMed interface of MEDLINE and LILACS. Only those reports of OFs that occurred in a series in the reporting authors' caseload were considered. All cases were confirmed fibro-osseous lesions histopathologically. The SR-included series had also to have used radiographs.
RESULTS
Of the 64 reports (including the Hong Kong report) considered, 32 reports and a total of 781 cases were included in the SR. Ten SR-included series were in languages other than English. OF affected females more frequently, but was three times more prevalent in the mandible. The mean age at first presentation was 31 years. The decade with the greatest frequency was the fourth. Females were in the majority except in the first decade. The main symptom in 66% of all SR-included cases was swelling (including deformation of the jaws). 31% were found incidentally. 84% of cases displayed buccolingual expansion; half of the mandibular cases exhibited downward displacement of the lower border of the mandible and 90% of maxillary cases involved the maxillary antrum. Only 28% of reports included follow-up; 12% of cases recurred or were reactivated.
CONCLUSIONS
Although long-term follow-up of large series that would have revealed the long-term outcomes of OF was lacking, a 12% recurrence rate is clinically significant and suggests that OFs should be considered for long-term follow-up.

Review
Ossifying fibromyxoid tumor (OFMT) is a mesenchymal neoplasm of uncertain lineage and intermediate biologic behavior. Involvement of the head and neck area is infrequent (10% to 15%) and intraoral presentation is very rare. An OFMT developing in the retromolar trigone of a 13-year-old male is presented, along with a comprehensive review of oral OFMT cases. Among 12 oral OFMTs (including the present case), most patients were male (72.7%), with a mean age of 30.3 (13-67) years. The tumors generally appeared as painless masses of firm or hard consistency (mean diameter 27.7 mm), most commonly located in the soft tissues of the mandible (50%). Common microscopic features included ossification, lack of atypia or high mitotic activity, and immunohistochemical positivity for S100 (5/7), vimentin (6/6), GFAP (3/6), and SMA (2/6). Recurrence was reported only in one case. Further characterization of this rare entity is needed to increase our understanding of its distinct clinical and histopathologic features.

The purpose of this study was to perform a systematic review of the literature concerning all documented cases of malignant transformation of craniomaxillofacial fibro-osseous lesions (FOLs). Three electronic databases were searched. Data were evaluated descriptively. Kaplan-Meier survival curves were constructed and compared using the log-rank test. A critical appraisal of included articles was performed through the Joanna Briggs Institute tool. A total of 19 studies including 27 patients were selected for data extraction. Twenty-six cases were initially diagnosed as fibrous dysplasia and one as ossifying fibroma. The mean age at the time of malignant transformation was 38.11 years, and the average time from initial diagnosis to malignant transformation was 18.2 years. The male:female ratio was 1:1.2, and the maxilla:mandible ratio was 1.5:1. The histological type of the malignant tumor was predominantly osteosarcoma. Follow-up was available for 21 patients. The 3-year overall survival rate was 51%. Mandible tumors and diagnoses other than osteosarcoma tended to have poor survival rates, but no significant difference was identified. We concluded that between all FOLs, only fibrous dysplasia seems to have a considerable increased risk of malignant transformation. Thus, a regular and long follow-up period is advised.

OBJECTIVE
Central giant cell granuloma (CGCG) can coexist with other benign lesions of the jaw. These hybrid lesions are diagnostically challenging to both oral pathologists and radiologists. This work systematically reviews the clinical and radiographic features of hybrid-CGCG lesions in the jaws.
MATERIALS AND METHODS
Three reviewers conducted an electronic search of five databases for histologically diagnosed hybrid-CGCG lesions in human jaws.
RESULTS
Thirty-four of 1224 articles met the inclusion criteria. Of 39 hybrid-CGCG lesions, 14 (35.9%) were central odontogenic fibroma, 11 (28.2%) were central ossifying fibroma, seven (17.9%) were fibrous dysplasia, and seven (17.9%) were other bone conditions. There were 22 females and 17 males with a mean age of 30.5 ± 19.9 years. 89.5% of hybrid-CGCG lesions were well defined, 57.9% were non-corticated, 60.5% were radiolucent, and 66.7% were in the posterior mandible. Most hybrid lesions affected the cortical plates by thinning, expansion, or perforation (93.1%), displaced, or resorbed teeth (60%).
CONCLUSION
The radiographic features of hybrid-CGCG lesions vary according to the concurrent bony lesion. Hybrid-CGCG lesions altered the radiographic appearance with the following entities: fibrous dysplasia, melorheostosis, and Paget's disease. Optimal imaging modalities are crucial to detail radiographic features and direct representative biopsy of suspicious sites that may host a CGCG hybridisation.
