1/93. 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 = cancer (Clic here for more details about this article) |
2/93. High-dose-rate mold brachytherapy of early gingival carcinoma: a clinical report.Two elderly edentulous patients with the diagnosis of early stage cancer of the upper gingiva were treated by customized dental mold brachytherapy. Locoregional tumor control was achieved in both patients. One patient is alive without any evidence of disease 36 months after treatment, the other patient died of distant metastasis shortly after brachytherapy. brachytherapy, being easy to apply with short treatment time and good acute tolerance, is a good choice and effective modality for the management of early stage gingival cancer, particularly in elderly patients.- - - - - - - - - - ranking = 0.4keywords = cancer (Clic here for more details about this article) |
3/93. Odontogenic fibromyxoma arising from the periodontal ligament.A case is reported of an intraosseous odontogenic fibromyxoma which presented as an epulis and appeared to arise from the periodontal ligament of an upper lateral incisor. True neoplasms rarely present in this fashion, and the literature reveals no report of an intraosseous myxomatous neoplasm exhibiting such clinical features. Evidence supporting the periodontal ligament origin of the lesion is presented and discussed.- - - - - - - - - - ranking = 0.72708018437277keywords = neoplasm (Clic here for more details about this article) |
4/93. Juvenile hemangioendothelioma: report of a case and review of the literature.A solitary juvenile hemangioendothelioma on the maxillary gingiva of a newborn white male has been presented. No recurrence or evidence of systemic involvement has been noted in the 18 months following excision. The literature was reviewed with emphasis on the varying location and behavior of the lesion and the methods of treatment. Simple excision of the isolated, histologically benign neoplasm is recommended provided adequate follow-up is assured.- - - - - - - - - - ranking = 0.36354009218638keywords = neoplasm (Clic here for more details about this article) |
5/93. 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 = 0.36354009218638keywords = neoplasm (Clic here for more details about this article) |
6/93. Apparent pokeweed mitogen cure of metastatic gum melanoma in an older dog.immunotherapy with plant mitogens has been of increasing interest to both authors, although their mutual attraction to these substances over the past two decades occurred independently and has taken divergent pathways from the start. Because of their clinical unavailability, Wimer's efforts have been confined to writing theoretical concepts on potential applications of the mitogens focusing on the L4 isolectin of PHA. Alternatively, Mann has worked actively with laboratory and experimental research involving PWM that he has extracted himself. As a sequel to a pilot study of PWM cancer treatment in pets whereby he supplies the mitogen, protocol, and data sheets and veterinarians supervise the administration, Mann acquiesced to widespread requests for inclusion in an extended investigation. Unfortunately, this arrangement has left Mann with little control over data submission, and until recently, only verbal reports have been received. The recent documentation of a three-year remission and apparent cure of gum melanoma metastatic to regional and hilar lymph nodes and to the lungs in an aged dog following PWM therapy has prompted this case report. The incredible response has inspired more aggressive attempts to obtain information from other recipients of the mitogen. The small total dose of 300 micrograms inducing a remission does speak for the remarkable potency of PWM that may be 500 or more times that of PHA. However, the possibility that melanoma is a uniquely responsive tumor is suggested by a 1971 article indicating complete remission of metastatic melanoma in an 18-year-old lad to an unexpectedly low total dose of 50 mg PHA. Preliminary reports on other tumors treated with PWM indicate some impressive responses have occurred, although they also suggest that Mann's regimen may sometimes require adjustments in dosages and other variables previously reviewed in theoretical PHA-L4 models, to which this case report now contributes validity.- - - - - - - - - - ranking = 0.2keywords = cancer (Clic here for more details about this article) |
7/93. 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 = 0.72708018437277keywords = neoplasm (Clic here for more details about this article) |
8/93. 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 = 0.36354009218638keywords = neoplasm (Clic here for more details about this article) |
9/93. Myxoid liposarcoma of the oral cavity with involvement of the periodontal tissues.BACKGROUND, AIMS: liposarcoma is the 2nd most frequent soft tissue sarcoma in adults, but it is extremely rare in the head and neck and, particularly, in the oral cavity. We report on a 25-year-old female who presented with a periodontal mass, extended from the right upper 3rd molar to the right upper 2nd premolar, covered by intact oral mucosa. The clinical differential diagnosis included peripheral giant cell granuloma, salivary gland neoplasms, squamous cell carcinoma of the gingiva, sarcoma and malignant lymphoma. methods: To accurately plan subsequent treatment, an excisional biopsy was performed and a myxoid liposarcoma was diagnosed. Consequently, the patient underwent wide excision of the neoplasm with maxillary en-block resection. RESULTS: The post-operative course was uneventful and the patient is alive and well 8 years after the original diagnosis. The authors stress the importance of considering soft tissue sarcomas in the diagnostic approach to patients with unusual periodontal neoplasms and to plan adequate surgical sampling of the lesion (i.e. excisional biopsy). CONCLUSIONS: This appears of pivotal importance as more limited specimens may result in inaccurate pre-operative diagnosis.- - - - - - - - - - ranking = 1.0906202765592keywords = neoplasm (Clic here for more details about this article) |
10/93. 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 = 0.2keywords = cancer (Clic here for more details about this article) |
