1/70. Gingival metastasis from a prostate adenocarcinoma: report of a case.prostate cancer is the cause of 10% of cancer-related deaths in males in the united states. Metastases are found late in the course of the disease. Metastatic tumors of the oral cavity are rare, representing about 1% of oral tumors and affect jaws much more frequently than soft tissues. Metastatic prostate cancer tends to involve the bones of the axial skeleton. In a recent review, 22 cases of metastases to the jawbones from prostate cancer were found in 390 cases. On the other hand, only 1 case of a metastasis to the oral soft tissues was reported. The authors describe the second case of oral soft tissue metastasis from a prostate cancer. The metastatic lesion was located in the gingiva. Clinicians should be aware of oral soft tissue metastases since they can be the first sign of a not yet diagnosed malignant tumor and they can be very easily confused with several different benign lesions.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
2/70. Gingival metastasis from a medullary thyroid carcinoma: case report.BACKGROUND: Metastatic tumors to the oral cavity are rare, representing about 1% of oral tumors, and they affect jaws more often than the oral soft tissues. methods: Fifteen cases of metastases to the jaw bones from thyroid carcinoma were found in a recent review, with no cases located in the oral mucosa. RESULTS: The authors describe the first cases of gingival metastasis from a thyroid medullary carcinoma. CONCLUSIONS: Periodontists must recognize oral soft tissue metastases because they can be the first sign of an undiscovered malignancy, and they can be easily mistaken with several different benign lesions.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
3/70. Gingival lesions and nasal obstruction in an immunosuppressed patient post-liver transplantation.Although rare, metastatic hepatocellular carcinoma (HCC) presenting only to the mandible, gingiva, and nasal cavity in patients subsequently found to have primary HCC has been reported. In the age of transplantation, certain HCC patients may receive treatment with an orthotopic liver transplant. Due to the proclivity of HCC for early micrometastases, immunosuppressive therapy can induce significant metastatic lesions. Nasal mass obstruction, gingival lesions, or facial growths in this population must be considered metastatic until proven otherwise.- - - - - - - - - - ranking = 5.2497103302222keywords = mandible (Clic here for more details about this article) |
4/70. Bilateral metastatic breast angiosarcoma to the mandibular gingiva: case report.Metastases to the jaws and oral soft tissues are rare. A case of breast angiosarcoma metastatic to the mandible and the gingiva, bilaterally in the premolar area is presented. The clinical, histological features and the management of the metastatic oral lesions are reported. Our case emphasises the possibility that in patients with history of breast angiosarcoma, oral inflammatory-like lesions may be an indication of a metastatic deposit.- - - - - - - - - - ranking = 5.7497103302222keywords = mandible, jaw (Clic here for more details about this article) |
5/70. Metastasis of breast carcinoma to mandibular gingiva.Metastatic tumours to the oral region are rare but more often involve the jaws rather than the oral soft tissues. In this report, an infiltrative ductal carcinoma of the breast that metastasised to the mandibular gingiva is presented. The patient consulted her dentist for what she thought was a dental abscess in the bicuspid region of the lower left jaw. However, her dentist referred her for a specialist opinion of the lesion. The patient's medical history revealed that she had undergone a breast 'lumpectomy' 1 year previously. A provisional diagnosis of primary or metastatic malignancy was made, and a biopsy was performed. Microscopically, the lesion showed features of a poorly differentiated infiltrative ductal carcinoma. Subsequent microscopic review of the primary lesion also showed a poorly differentiated infiltrating ductal carcinoma of the breast identical to the features observed in the metastatic lesion.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
6/70. Metastatic transitional cell carcinoma of the urinary bladder presenting as a mandibular gingival swelling.Oral cavity metastases mostly originate from the breasts, lungs, or kidneys. Transitional cell carcinoma (TCC), the most frequent malignant tumor of the urinary bladder, rarely metastasizes to the jaws. To the best of our knowledge, only 8 cases of bladder carcinoma have been reported in the English literature to metastasize to the jawbones. A new case of mandibular metastasis of urinary bladder TCC with extension to the gingiva is presented in a 64-year-old white man. The patient was referred for a periodontal infection of the upper right first molar. The clinical examination also showed a gingival swelling located in the lower left premolar region with a hypoasthesia of the left side of the lower lip. The gingival mass was biopsied, and the microscopy showed a mandibular metastatic TCC of the urinary bladder extending to the gingiva. Periodontists should be aware that, although gingival metastases are rare, when they occur they may mimic other local benign pathological conditions.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
7/70. Congenital epulis: an ultrastructural and immunohistochemical case study.We report a case of an otherwise healthy, two days old, female with a a mass derived from the mandible. light microscopy findings were compatible with the diagnosis of congenital epulis. The lesion showed negative staining for S-100 protein, which is a characteristic finding in cases of epulis and distinguishes it from granular cell tumor. The characteristic electron microscopy findings, as well as other features of epulis in relation to the theories for its possible origin are also reviewed- - - - - - - - - - ranking = 5.2497103302222keywords = mandible (Clic here for more details about this article) |
8/70. Release of extra-articular ankylosis by coronoidectomy and insertion of a free abdominal flap: case report.INTRODUCTION: It is generally agreed that an effective treatment for extra-articular ankylosis may be coronoidectomy and excision of scar tissue. But these conventional procedures have shown a high rate of recurrence of ankylosis due to heterotopic bone and fibrous tissue formation. OBJECTIVE AND PATIENT: We report a case in whom a coronoid osteotomy and insertion of a free abdominal flap was used to treat ankylosis of the mandible following radiotherapy for maxillary cancer. RESULTS: This procedure prevented recurrence of ankylosis by heterotopic bone and fibrous tissue formation. In addition, this flap reduced the risk of postoperative infection and promoted primary healing. CONCLUSION: The procedure, coronoidectomy and insertion of a free flap, was successful because the well-vascularized musculocutaneous flap occupied the dead space, and replaced the shortage of oral mucosa consequently inhibiting the recurrence of extra-articular ankylosis.- - - - - - - - - - ranking = 5.2497103302222keywords = mandible (Clic here for more details about this article) |
9/70. Multiple congenital epulis of the alveolar ridge and tongue.Congenital granular cell tumor, also known as congenital epulis, is a very rare lesion seen in newborns. The typical presentation is a solitary nodule occurring on the gingiva of the anterior alveolar ridge of either jaw. Multiple-site involvement is seen very seldom but has been noted on the same or different alveolar ridges. However, tongue involvement is exceptional, and there have been only three cases reported involving both the alveolus and the tongue. A female newborn with multiple congenital epulis on the mandibular alveolar ridge and tongue is presented, and her preferred treatment and histopathological diagnosis are discussed.- - - - - - - - - - ranking = 0.5keywords = jaw (Clic here for more details about this article) |
10/70. Peripheral calcifying odontogenic cyst.BACKGROUND: Calcifying odontogenic cyst (COC) is a rare lesion representing about 1% of jaw cysts. It may occur in a central (intraosseous) or peripheral (extraosseous) location. METHOD: A case of peripheral COC located on the gingiva, appearing as a painless, circumscribed, pink nodule has been reported. RESULTS: Peripheral, in contrast to central, COC tends to affect older patients. Peripheral COC is a less aggressive lesion than the central counterpart, and a simple excision biopsy is curative. CONCLUSION: The histological finding of a keratinized epithelium rich in ghost cells has helped in making the diagnosis.- - - - - - - - - - ranking = 0.5keywords = jaw (Clic here for more details about this article) |
