1/235. 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 = 1keywords = mouth (Clic here for more details about this article) |
2/235. 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 = 0.00025460613316158keywords = ulcer (Clic here for more details about this article) |
3/235. 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 = 1.25keywords = mouth (Clic here for more details about this article) |
4/235. 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 = 0.25keywords = mouth (Clic here for more details about this article) |
5/235. Metastasising malignant lymphoma mimicking necrotising and hyperplastic gingivostomatitis.This paper presents the case of a 65 year-old woman suffering from recurrent oral aphthoid ulcers which rapidly evolved towards hyperplastic and ulcerated lesions over the entire floor of the mouth. The initial lesions were interpreted as non-specific aphthoid ulcers. Later, a tentative diagnosis of necrotising stomatitis with secondary reactive proliferating epithelial hyperplasia was made. The clinical symptoms and the immuno-phenotyping of lymphocytes circulating in the peripheral blood suggested the diagnosis of CD30-positive large cell anaplastic lymphoma. The biopsy showed only a pseudoepitheliomatous hyperplasia, reactive infiltrates and no lymphoma cells. The disease ran a fulminant course leading to death within 4 weeks due to acute gastro-intestinal bleeding. autopsy revealed infiltrates of CD30 large cell anaplastic lymphoma in a submandibular lymph node, in a thrombus stenosing the right subclavian vein, in the spleen, the anterior and posterior gastric wall as well as in the depth of the tumour on the floor of the mouth. The clinical and histopathological spectrum of CD30 large cell anaplastic lymphoma is considerably variable. The particular feature of pseudoepitheliomatous hyperplasia has been reported especially in CD30 anaplastic large cell lymphomas. An early correct diagnosis is rendered difficult in insufficient biopsy size, becauses this type of lymphoma often simulates other inflammatory or neoplastic skin diseases. Thus, with a necrotising and hyperplastic gingivostomatitis, the diagnosis of a CD30 anaplastic large cell lymphoma should be considered.- - - - - - - - - - ranking = 0.50076381839948keywords = mouth, ulcer (Clic here for more details about this article) |
6/235. High dose rate microselectron mould ratiotherapy of a widespread superficial oral cancer.Treatment of a case of widespread superficial oral squamous cell carcinoma with external beam irradiation, followed by high dose rate Microselectron mould radiotherapy, is reported. The tumor disappeared macroscopically after treatment, but there was infield recurrence in the buccogingival sulcus where the radiation dose might have been inadequate. Apart from some radiation mucositis within the treated area, edema and a superficial ulcer were observed in the tongue. These were considered to be due to radiation overdose. Although there is room for improvement, this mode of treatment has something to offer patients with hard-to-cure cancer.- - - - - - - - - - ranking = 0.00025460613316158keywords = ulcer (Clic here for more details about this article) |
7/235. Sliding dermoid cyst. A case report.Dermoid cysts of the oral cavity usually present as a solitary, painless mass in the midline or, on occasion, more laterally in the submandibular region. A patient is described who presented with a mass in the submandibular region, which could be made to appear or disappear at will. This unusual manifestation occurred as the cyst plunged around the posterior border of the mylohyoid on tensing the floor of the mouth.- - - - - - - - - - ranking = 0.25keywords = mouth (Clic here for more details about this article) |

9/235. Pigmented dermoid cyst of the floor to the mouth: a comparison of two cases.Two cases of very large midline sublingual dermoid cysts are reported; one case had unique features. A useful surgical technique for the management of such cysts in described. The failure of the cyst in one case to penetrate the geniohyoid septum despite its large size and the presence of melanin pigmentation in the cystic lining are emphasized.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
10/235. Spontaneously relapsing clonal, mucosal cytotoxic T-cell lymphoproliferative disorder: case report and review of the literature.Primary T-cell lymphoma of the gastrointestinal tract is a rare and usually aggressive disorder that may be associated with celiac disease. The authors describe a unique case of a clonal proliferation of CD8 T cells involving the oral mucosa, ileum, and colon of a 35-year-old man that has regressed spontaneously and recurred numerous times over a 9-year period without treatment. The patient's symptoms were limited to occasional rectal bleeding and recurring painful oral ulcers. Within the intestine, these collections of small T cells induced minimal architectural distortions and did not show extensive epitheliotrophism. polymerase chain reaction and sequencing analyses revealed that the identical T-cell clone has been present for more than 9 years and in different mucosal locations in this patient. This may represent a unique T-cell lymphoproliferative process akin to a mucosal counterpart of lymphomatoid papulosis of the skin.- - - - - - - - - - ranking = 0.00025460613316158keywords = ulcer (Clic here for more details about this article) |
