• Assessment of MDM2 Gene Locus Amplification by Fluorescence In-Situ Hybridization in Juvenile Ossifying Fibroma

  Head and Neck Pathology · 2024-08-06 · 1 citations

  articleOpen access

  Juvenile ossifying fibroma (JOF) is an uncommon benign fibro-osseous lesion (BFOL) of the maxillofacial bones with a locally aggressive nature and a high recurrence rate. Murine Double Minute 2 (MDM2) is an oncogene located at chromosome 12 (12q13-15) that inhibits the tumor suppressor gene TP53. The presence of MDM2 gene locus amplification is a useful molecular adjunct in the evaluation of some sarcomas, including low-grade intramedullary osteosarcoma (LGIOS). JOF and LGIOS have some overlapping clinical and histopathological features. The aim of this study is to evaluate a series of JOF for the presence of MDM2 gene locus amplification using fluorescence in-situ hybridization (FISH). MATERIALS AND METHODS: With IRB approval, a search of the institutional files of the archives of the Oral Pathology and Surgical Pathology biopsy services at the University of Florida Health was performed. The cases were re-evaluated by an oral pathology resident, an oral and maxillofacial pathologist, and a bone and soft tissue pathologist. Cases with consensus in diagnosis were selected (n = 9) for MDM2 testing. Testing by FISH for MDM2 gene locus amplification was applied to all retrieved cases. RESULTS: The examined cases were all negative for MDM2 gene locus amplification via FISH testing. CONCLUSION: In our small series, JOF did not demonstrate MDM2 gene locus abnormality, a characteristic of LGIOS. This finding suggests that JOF has a distinct underlying pathogenesis. If confirmed in a larger series, these findings may be useful in distinguishing these two entities in cases with overlapping features or when minimal biopsy material is available.

• Xanthoma of the Jaw Bones: Cases Series and Review of Literature

  Head and Neck Pathology · 2024-03-19 · 4 citations

  reviewOpen access

  BACKGROUND: Intraosseous xanthomas are rare benign lesions sometimes associated with excess lipid production. Xanthoma of the jaw bones (XJB) was first reported in 1964, and fewer than 50 cases have been reported in the English literature to date. The etiopathogenesis of XJB is highly suggestive of a reactive process or a metabolic condition. METHOD: Seven cases of XJBs were retrieved from the archives of 4 oral and maxillofacial pathology services. Clinical, radiographic and histopathologic features of all these cases were retrospectively analyzed. Immunohistochemical (IHC) stains for S100 and CD68 were performed. RESULTS: All seven cases involved the mandible. Patients' age ranged between 13 and 69 years with an evenly distributed female to male ratio. One patient had a medical history of hyperlipidemia, but the medical and dental histories of the others were unremarkable. For most cases, XJB was an incidental finding discovered during routine radiographic examination. Swelling and cortical expansion were noted in a few cases. Radiographically, cases typically presented as either well-defined multilocular or unilocular lesions, which were either radiolucent or mixed radiolucent/radiopaque. All the lesions were treated with surgical curettage and no recurrence was observed during subsequent follow-ups. Each of the seven cases exhibited sheets of foamy macrophages. The diagnosis is established by exclusion of entities with overlapping microscopic features and involved correlation with the clinical, histological, radiographic and IHC profiles. Immunohistochemically, all the cases expressed diffuse positivity for CD68 and were negative for S100. CONCLUSION: XJB is a rare lesion of unknown etiology, which may mimic other benign or reactive jaw lesions. Due to its rarity and the potential diagnostic challenges it presents, clinicians must remain vigilant and consider CXJ in their differential when assessing radiolucent jaw anomalies.

• An Unusual Histopathological Presentation of Mandibular Osteosarcoma

  Head and Neck Pathology · 2024-11-19 · 1 citations

  articleOpen access

  Jaw osteosarcoma (JOS) is a rare, distinct variant that differ from long bone osteosarcoma (LBOS) in several aspects. JOS typically appears about twenty years later than LBOS, displays a lower propensity for metastasis to other organs, and exhibits better survival rates. The dissimilarities in clinical and biological behavior between JOS and LBOS are likely due, at least in part, to variations in their respective microenvironments. In this report, we present a case of OS affecting the mandible in a young patient. This case displayed classic radiographic features but a unique histopathological presentation, posing a diagnostic challenge for pathologists, especially if encountered in small biopsies.

• COVID-related mucormycosis mimicking dental infection

  Oral and Maxillofacial Surgery Cases · 2023-05-06 · 2 citations

  articleOpen access

  A recent increase in the prevalence of mucormycosis of the head and neck in patients who have recovered from COVID-19 following hospitalization has been reported. A Majority of the cases have been reported from India. Conditions such as diabetes mellitus, use of corticosteroids for other autoimmune conditions, organ transplant, immunosuppression, immunodeficiency, and malignancies especially hematologic ones, are all known risk factors for mucormycosis. Recently, hospitalization for COVID-19 has been added to the list of risk factors for opportunistic mucormycosis infection. This is likely attributable to the high doses and prolonged use of corticosteroids in the treatment of hospitalized COVID-19 patients. Case Description: Two patients with post-COVID-19 associated rhinocerebral mucormycosis presented with profound unexplained dental disease including tooth mobility and dental abscess mimicking periodontal disease. The patients were previously hospitalized for COVID-19 and received prolonged treatment with high doses of corticosteroids. The patients responded well to the surgical debridement with or without antifungal therapy. Conclusion: Oral healthcare providers including oral and maxillofacial surgeons, dentists, dental hygienists, and other dental practitioners can play a vital role in the recognition and early diagnosis of rhinocerebral mucormycosis given the large number of patients with severe COVID-19 infection who have recovered following hospitalization and/or received long-term high doses of immunosuppressive treatment.
