    Ossifying fibroma of the mandible and craniofacial bones

    Diagnostic Histopathology, Volume 21, Edition 9, 2015, Pages 351-358

    Fibrobone lesions encompass a variety of pathological processes in which normal bone is replaced by fibrous tissue containing varying amounts of mineralized material. As the characteristics are quite similar, the definitive diagnosis of these lesions requires an accurate correlation of clinical, radiological and histopathological findings.

    Ossifying fibroma is a fibrous bone tumor that usually affects the mandible and consists of three distinct entities, all with overlapping characteristics. We examined the clinicopathological and imaging features of cementum ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF) and juvenile psamous ossifying fibroma (JPOF).

    Mixed peripheral giant cell granuloma and peripheral ossifying fibromatous lesions: rare case report and literature review

    Journal of Oral and Maxillofacial Surgery, Medicine and Pathology, Bd. 29, No. 6, 2017, S. 587–593

    Mixed lesions with a giant cell granuloma (GCG)-like component associated with central odontogenic fibroma (CFO) and fibroskeletal lesions have been reported in the literature since 1992; Marginal cases, on the other hand, are extremely rare. Therefore, the objective of this manuscript is to report a case of mixed lesion composed of peripheral giant cell granuloma (PGCG) and peripheral ossifying fibroma (POsF), highlighting the clinical, radiological, histopathological, therapeutic and prognostic aspects of this type of lesion . Thus, our case presentation included a 31-year-old dermatology patient who presented with a large, asymptomatic exophytic lesion in the alveolar mucosa of the left mandible, with radiographic evidence of an irregular opaque lesion within the area of ​​soft-tissue injury. An excisional biopsy is performed under local anesthesia. Histopathological analysis revealed fragments of oral mucosa lined by parakeratotic and atrophic stratified squamous epithelium with areas of ulceration; lamina propria showed dense connective tissue with numerous inflammatory multinucleated giant cells (MGCs), spindle cells, blood vessels, hemorrhage, and hemosiderin infiltration; in addition, deposits of trabecular bone matrix mixed with MGCs, proliferation of fibroblasts and collagen fibers were observed. If this association between PGCG and POsF occurs, the possibility that PGCG presents bone formation must be ruled out. Therefore, a mixture of PGCG and POSF may pose a diagnostic challenge for pathologists, and more cases with histopathological features similar to our case should be reported to clarify the suspected histogenesis of this lesion.

    SATB2 is commonly expressed in ossified and non-ossified perioral fibromas in the gingival region, but not in reactive fibromatous lesions in other intraoral sites.

    Annals of Diagnostic Pathology, Band 46, 2020, Artikel 151510

    (Video) Ossifying Fibroma

    Ossified and non-ossified perioral fibroids (POF) of the gingival and alveolar mucosa are small localized fibronodular, cellular lesions that can be caused by various external/internal physical and chemical stimuli or injuries. Central foci of metaplastic bone tissue characterize and define ossification variants. The intrinsic tendency of these lesions to ossify remains unclear. Here we analyzed SATB2 expression as an osteoblast transcription and differentiation factor in 28 gingival POFs (10 of which are ossified) and compared with 28 fibrotic lesions from different non-gingival intraoral sites. SATB2 strong to moderate diffuse nuclear immunoreactivity was detected in all ossified (10/10; 100%) and 8/18 (44%) non-ossified gingival FOPs, but only in 1/28 (3%) of nodular fibrous lesions observed in non-ossified gingival POFs - gingival oral reactivity. This study is the first to demonstrate consistent expression of the osteoblastic marker SATB2 in ossified and non-ossified FOPs in the gingival area, but this marker is absent in reactive fibrous lesions at other oral sites. This finding is compatible with the suspected formation of gingival FOP in the periodontal ligament and could explain the frequent ossification observed there. This finding should be taken into account when evaluating SATB2-positive oral tumor biopsies in order to avoid misinterpretations.

    Orthokeratotic odontogenic cyst (OOC): clinicopathological and radiological characteristics of a series of 48 cases

    Pathology - Research and Practice, Volume 236, 2022, Article 153969

    To demonstrate the clinicopathological and radiological characteristics of orthokeratotic odontogenic cysts (COOs) and to analyze the proliferative activity of epithelial cells between COOs and keratotic odontogenic cysts (COCs).

    (Video) Ossifying Fibroma (Complete Lecture) | For NBDE, NDEB, MDS & FCPS

    Clinicopathological and radiological analyzes were performed in all cases of OOC. Expression of cell proliferation markers Ki-67 and cyclin D1 was detected by immunohistochemistry.

    A total of 48 OOC patients were included, including 28 men and 20 women. The mean age was 33.50 years, ranging from 13 to 61 years. The mandible was affected five times more often than the maxilla (40 in the mandible, 8 in the maxilla). All OOCs were unilocularly radiolucent with well-defined margins, and 30 of 36 showed loss of buccal or lingual cortical continuity on computed tomography (CT) images. Root resorption occurred in three cases and tooth displacement occurred in four cases. CT showed that the mean volume of the cyst was 7794.25 ± 6952.98 mm3.All cysts underwent enucleation or decompression after enucleation. The mean follow-up time was 32.50 ± 27.58 months (6-65 months) and the overall recurrence rate was 4.44% (2 cases out of 45). Ki-67 and cyclin D1 expression was significantly decreased in OOCs compared to OKCs (P<0.001).

    OOCs were more common in the mandible, were slightly masculine, and had less proliferative activity than COCs. On radiographs, OOC is more likely to be associated with buccolingual expansion and destruction of cortical bone. Due to the low invasiveness and recurrence rate, enucleation or decompression in combination with enucleation is the treatment of choice for OOC.

    A retrospective study of 15 cases of juvenile ossified fibroids of the mandible

    International Journal of Oral and Maxillofacial Surgery, Volume 45, Issue 3, 2016, pages 368-376

    The treatment of patients with juvenile ossifying fibroma (JOF) remains controversial. Fifteen cases of JOF in the mandible were reviewed to explore the association between different treatments and patient outcomes. Five patients were male and 10 patients were female. Patients' age at baseline was between 7 and 18 years (mean 10.9 years). Nine tumors were in the mandible and six in the maxilla. These cases usually present clinically with painless swelling of the jaw (9/15, 60%); 40% (6/15) of cases are associated with pain, diplopia, nasal congestion and/or rapid growth. JOF images can appear radiolucent, blended, or matte. Pathological examination revealed 10 cases of juvenile trabecular ossifying fibroma (JTOF) and 5 cases of juvenile psamous ossifying fibroma (JPOF). Regarding treatment options, 6 patients initially received radical surgery; 9 patients received conservative treatment, of which 6 patients (6/9, 66.7%) had one or more relapses. At the end of follow-up, 12 cases had no evidence of tumor recurrence and 3 cases survived with tumor. In summary, surgeons must formulate surgical plans based on lesion extent, recurrence, growth rate, and family selection and monitor these patients closely.

    Ossifying fibroma: analysis of treatment approaches and recurrence patterns

    Journal of Oral and Maxillofacial Surgery, Volume 74, Issue 12, 2016, Pages 2409–2419

    (Video) peripheral ossifying fibroma-English

    Ossifying fibroma (OF) is the most common of the three fibroskeletal lesions of the mandible and has a variable rate of recurrence. The final operational plan has yet to be announced. The aim of this study was to determine the clinical and radiological features of OP, assess its treatment patterns and recurrence, and develop a surgical protocol in a tertiary hospital in South Africa.

    A retrospective series of all histopathologically diagnosed cases of OC from 1976 to 2014 was performed. Demographic, clinical presentation, and radiological characteristics were analyzed. Management and follow-up data were also recorded for each case. Based on these findings, an operation plan was developed.

    A total of 61 cases were included in this study. Most patients were female (63.9%) and younger than 40 years (73.9%) and only a few cases were symptomatic (29.5%). The posterior region of the mandible was the most affected (55.5%) and most of the lesions were radiopaque (49.2%) and well defined (93.6%). Surgical curettage was used in most cases (68.2%). After a mean follow-up of 20 months, there was only one case of recurrence, with a recurrence rate of 6.7%.

    Lesions in our population were more radiopaque and larger than those in published data. Surgical curettage is an acceptable treatment option with a low recurrence rate, and resection should be reserved for invasive and recurrent lesions.
