1/445. Solitary fibrous tumor of the oral cavity: report of a case.A case of benign solitary fibrous tumor of the oral cavity is reported. The tumor occurred in the buccal mucosa of a 34-year-old woman. The surgically removed tumor was 1.5 x 1.2 x 1.0 cm in size and well circumscribed. Histologically, the tumor was composed of spindle-shaped cells that were predominantly arranged haphazardly. hemangiopericytoma-like areas and collagenous areas were also noted. Immunohistochemically, the tumor cells were positive for CD34 and vimentin. To our knowledge, this is only the second report of solitary fibrous tumor involving the oral cavity.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/445. Successful treatment of obstructive sleep apnea with use of nasal continuous positive airway pressure in three patients with mucosal hemangiomas of the oral cavity.cysts and benign tumors are uncommon causes of obstructive sleep apnea (OSA), and surgical removal is usually favored. In patients in whom an operation poses a high risk, however, nasal continuous positive airway pressure (CPAP) may prove beneficial. We describe three patients with hemangiomas of the oral cavity in whom polysomnography revealed moderate to severe OSA. In all three patients, nasal CPAP effectively decreased sleep-related disordered breathing events and dramatically improved their sleep. To our knowledge, this is the first report of OSA associated with hemangiomas involving the upper airway. Our experience suggests that nasal CPAP therapy is effective and well tolerated in such patients.- - - - - - - - - - ranking = 0.83333333333333keywords = oral cavity, cavity (Clic here for more details about this article) |
3/445. Adenosquamous carcinoma of the mouth: a rare variant of squamous cell carcinoma.Adenosquamous carcinoma is a rare tumour in the oral cavity and is characterised histologically by carcinomatous change in surface epithelium, in association with adenocarcinoma affecting the ducts of minor salivary glands. Only a dozen cases have previously been reported in the oral cavity, but all have shown an aggressive course with 60% of patients dying of disease. We report three further cases and review the literature, which suggests that this lesion should be regarded as a high-grade variant of squamous cell carcinoma.- - - - - - - - - - ranking = 0.53810077019566keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
4/445. Burkitt-like lymphoma presenting as a periodontal disease in AIDS patients: a report of two cases.Burkitt-like lymphoma of the oral cavity is relatively uncommon in patients with acquired immunodeficiency syndrome (AIDS). The lesion usually appears as a solitary ulcerated mass with rapid onset. Some may present initially as gingival inflammation which delays final diagnosis and treatment. This report describes the presentations of multifocal intraoral Burkitt-like lymphoma in two Thai heterosexual men with AIDS. The clinical features and the radiographic findings in both cases mimicked a periodontal disease, showing extensive widening of the periodontal ligament space and loss of lamina dura in all segments of the molar teeth. The patients eventually died 5 and 14 months after they were diagnosed with hiv infection.- - - - - - - - - - ranking = 0.16666666666667keywords = oral cavity, cavity (Clic here for more details about this article) |
5/445. October 1998--61 year old male with brain tumor and oral, lung, and palpebral masses.In Jan. 97 a gliosarcoma was diagnosed in a 61-year- old man after a 6-month history with neurological deficits. A total physical examination, laboratory tests, chest x-ray and abdominal ultrasound scanning revealed no gross abnormalities. Surgery was followed by brain radiation therapy and 6 months later there were metastases to the oral cavity, right palpebra and both lungs. The histological findings of the oral and palpebral metastases revealed only the sarcomatous component. We are aware of 15 cases of gliosarcoma with extraneural metastases, and in 4 of these, the metastases contained only the sarcomatous component. We believe that our case represents the fifth case of pure sarcomatous metastases.- - - - - - - - - - ranking = 0.16666666666667keywords = oral cavity, cavity (Clic here for more details about this article) |
6/445. Customized mold brachytherapy for oral carcinomas through use of high-dose-rate remote afterloading apparatus.OBJECTIVE: The aim of this study was to investigate the role of the combined use of customized molds and recently available remote afterloading brachytherapy apparatus with more flexible catheters in the treatment of superficial oral carcinomas. STUDY DESIGN: Four patients with oral squamous cell carcinoma who were treated through use of this combined technique were analyzed retrospectively. The molds were made from transparent acrylic resin through use of a dental technique. The combined approach was applied as a boost therapy after external irradiation. RESULTS: The 4 patients had had no recurrence of tumor or radiation injury by the end of the follow-up period. CONCLUSIONS: The combined technique could be an excellent method of treating superficial carcinomas of the oral cavity.- - - - - - - - - - ranking = 0.16666666666667keywords = oral cavity, cavity (Clic here for more details about this article) |
7/445. melanoma of the face and mouth in nigeria. A review and comment on three cases.The absolute incidence of melanoma at all sites in blacks is higher than is commonly credited. There is a shift in site incidence to less pigmented areas including the mucosae but oral melanoma is still rarely reported in Africans. An unusual case of facial melanoma arising in a childhood naevus, and two oral melanomas, all in Nigerians, are described. The salient clinical features and the treatment of these cases are discussed, and the possible relationship between pigmented patches and melanomas in the mouths of blacks is examined.- - - - - - - - - - ranking = 0.25595929607791keywords = mouth (Clic here for more details about this article) |

9/445. Solitary fibrous tumor of the oral cavity: an uncommon location for a ubiquitous neoplasm.Solitary fibrous tumor is an uncommon soft tissue tumor initially reported in the pleura but recently described in other sites of the body. To date, only 5 examples of oral solitary fibrous tumor have been reported. Here, we describe 2 additional cases of this tumor in the oral cavity. The tumors were composed of small to medium-sized spindle cells with bland cytologic features; these cells were haphazardly arranged in highly cellular sheets or ill-formed fascicles as well as in hypocellular areas with hyalinized blood vessels. Both tumors contained blood vessels with a hemangiopericytomalike appearance and expressed vimentin, CD34, and CD99. One case was also strongly positive for bcl-2. The diagnosis of solitary fibrous tumor may be difficult inasmuch as it shares a number of histologic features with other soft tissue tumors. awareness of its occurrence in the oral cavity is important so that confusion with other spindle cell neoplasms can be avoided.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
10/445. Transmucosal fine-needle aspiration diagnosis of intraoral and intrapharyngeal lesions.OBJECTIVES: The effectiveness of fine-needle aspiration biopsy (FNAB) for the diagnosis of neck, thyroid, and salivary gland masses is well documented. Very few reports explore the potential of an intraoral FNAB approach for the diagnosis of submucosal lesions. We describe our technique and present case examples of pertinent differential diagnostic entities. We recommend an expanded role for FNAB of the oral cavity and oropharynx. STUDY DESIGN: Retrospective review. methods: A uniform technique was employed for transmucosal FNAB of 76 patients with intraoral masses. In applicable cases, cytology results were compared with traditional biopsy methods and permanent histopathologic specimens for accuracy. RESULTS: Our experience demonstrates the high sensitivity (93%) and specificity (86%) of intraoral FNAB when compared with biopsy by conventional means. FNAB provides distinct advantages for the cytologic diagnosis of submucosal lesions, which may be difficult to reach and adequately sample through conventional biopsy. FNAB of the tonsil and tonsillar fossa provides a safe and effective means of diagnosing both lymphoma and squamous cell cancer. Transmucosal FNAB via the mouth led to rapid diagnosis of a number of benign and malignant lesions. Applying this uniform FNAB technique, we had no significant complications. CONCLUSION: We recommend transmucosal FNAB as an effective means for highly accurate diagnosis of submucosal lesions of the oral cavity and oropharynx. CLINICAL RELEVANCE: Traditional biopsy techniques in the oral cavity may require anesthesia and may have diagnostic difficulties, particularly for submucosal lesions. Transmucosal FNAB overcomes these shortcomings by providing a minimally invasive means to rapid diagnosis of intraoral lesions.- - - - - - - - - - ranking = 0.55119185921558keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
