1/104. 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 = cavity (Clic here for more details about this article) |
2/104. Metastatic adenocarcinoma of gingiva. Report of a case.A case of metastatic neoplasm developing in the gingiva from a primary lesion, probably sited in the gastric mucosa, has been reported. In this case, the first demonstrable metastatic lesion was located in the gingiva. The dentist has a great responsibility in detecting malignancy in the oral cavity because of his opportunities during routine examinations.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
3/104. 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 = cavity (Clic here for more details about this article) |
4/104. Primary gingival malignant melanoma. Report of 3 cases.BACKGROUND: Malignant melanoma is rare in the oral cavity and accounts for less than 1% of all melanomas. Nevertheless, the disease can be fatal, and early diagnosis and treatment may improve prognosis dramatically. The purpose of this paper is to report 3 new cases of primary malignant melanoma of the oral cavity arising in the gingiva, and to review the literature regarding intraoral melanoma. methods: Three cases are presented. One case was in the right mandibular molar area; the second in the right maxillary canine-premolar area; and the third in the left mandibular canine-premolar region. All patients were treated surgically, with postoperative radiotherapy. RESULTS: The first patient lived for 2 years and the second for 3 years before distant metastases were diagnosed from which they subsequently died. The third patient was lost from follow-up after 18 months. CONCLUSION: Primary oral malignant melanoma is a deadly disease. Early suspicion of this disease will allow prompt treatment and increase the prognosis for these patients.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
5/104. 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 = 1keywords = cavity (Clic here for more details about this article) |
6/104. Hepatocellular carcinoma metastatic to the oral mucosa: report of a case with multiple gingival localizations.BACKGROUND: Metastases to the oral mucosa are rare, representing less than 1% of the tumors at this site. Most of these metastatic neoplasms originate in the lungs, kidneys, and liver. methods: The clinicopathologic features of an occult hepatocellular carcinoma, metastatic to the oral mucosa, are reported. The patient, a 70-year-old male, complained of 3 distinct polypoid, reddish lesions of the antero-inferior alveolar crest and both the right and left postero-superior attached gingiva, without bone involvement. The lesions were excised, with the clinical diagnosis of multiple vascular tumors, formalin-fixed, paraffin-embedded, cut and stained with hematoxylin and eosin. Consecutive sections were immunostained for alpha-1-antichymotrypsin, CEA, cytokeratins, EMA, hepatocyte antigen, PSA, S-100 protein, and thyroglobulin, using the alkaline phosphatase/anti-alkaline phosphatase technique. RESULTS: The morphologic features of the lesions were consistent with the diagnosis of carcinoma with trabecular and glandular patterns and bile secretion; furthermore, immunohistochemical reactivity for alpha-1-antichymotrypsin, cytokeratins, CEA, EMA, and hepatocyte antigen was demonstrated and the hepatic origin of the tumor was postulated. ultrasonography demonstrated a liver mass, which was biopsied and treated by chemoembolization. While no further complications occurred in the oral mucosa, the patient died 8 months after the diagnosis for widespread diffusion of the tumor to the lungs and brain. CONCLUSIONS: This case emphasizes the need to include metastatic tumors in the differential diagnosis of atypical neoplasms of the oral mucosa and to evaluate the opportunity of surgical treatment in order to preserve the functions of the mouth, even if the prognosis of the primary tumors remains unfavorable.- - - - - - - - - - ranking = 0.26291208940426keywords = mouth (Clic here for more details about this article) |
7/104. Three cases of palatal polyps in infants.Fibrous lesions are common in the oral cavity, however, in infants they are rarely reported. We present three cases of palatal polyps in infants aged 2 days, 3 months and 7 months. In two cases, the treatment was surgical removal and in one case the polyp decreased in size and surgical removal was not required. In two infants, the diagnosis was confirmed histologically as fibroepithelial hyperplasia.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/104. Chorioepithelioma presenting as a bleeding gingival mass.A case is reported in which a very malignant neoplasm appeared clinically to be a pregnancy tumor or a hemangioma. There was, of course, no question as to the cause of death in this particular case. It was of interest because of the rarity of the tumor, the metastasis to the oral cavity, and the fact that the final diagnosis was established from pathologic examination. The case demonstrates, with emphasis, the great importance of biopsy and routine pathologic examination of all tissue for accurate and correct diagnosis, regardless of its clinical appearance.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/104. Gingival and cutaneous angiosarcoma.Multiple oral and cutaneous nodular and papular reddish-blue lesions are described in the case of a 60-year-old woman. The duration of the lesions was more than 1 year, with the oral lesion preceding the skin lesions. Histopathological examination revealed malignant vascular tumour with changes consistent with angiosarcoma. Angiosarcoma is an extremely rare malignant tumour of the oral cavity, and the present case describes oral and skin lesions with a unique clinical behaviour.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/104. Soft tissue myxoma of the gingiva: report of a case and review of the literature of soft tissue myxoma in the oral region.Soft tissue myxoma of the oral cavity is extremely rare. We present a case of soft tissue myxoma arising from a mandibular anterior gingiva in a 51-year-old male patient. Histological examination showed islands of odontogenic epithelium scattered in the mucinous stroma. This lesion was supposed to have a odontogenic origin. The clinical differences between soft tissue myxoma with bone destruction and those without bone destruction are also discussed by a review of the literature.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
