1/7. basal cell nevus syndrome. A case report.An 11-year-old boy with multiple dentigerous cysts in the maxilla and mandible is described. Other findings seen in the face, plantar skin, skeletal system and oral cavity indicated the lesions to be due to the basal cell nevus syndrome. This was further confirmed by the presence of similar abnormalities in his father and brother.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/7. White sponge naevus with minimal clinical and histological changes: report of three cases.White sponge naevus (WSN) is a rare autosomal dominant disorder that predominantly affects non-cornified stratified squamous epithelia: oral mucosa, oesophagus, anogenital area. It has been shown to be related to keratin defects, because of mutations in the genes encoding mucosal-specific keratins K4 and K13. We illustrate three cases diagnosed as WSN, following the clinical and histological criteria, with unusual appearance. They presented with minimal clinical and histological changes that could be misleading in the diagnosis. The patients showed diffuse irregular plaques with a range of presentations from white to rose coloured mucosae involving the entire oral cavity. In one case the lesion was also present in the vaginal area. The histological findings included epithelial thickening, parakeratosis and extensive vacuolization of the suprabasal keratinocytes, confirming WSN diagnosis. Clinical presentation and histopathology of WSN are discussed in relation to the differential diagnosis of other oral leukokeratoses.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
3/7. White sponge nevus. diagnosis by light microscopic and ultrastructural cytology.The lesions of white sponge nevus, an autosomal dominant abnormality of squamous epithelial differentiation that primarily affects the oral cavity, may be grossly similar to those of other hereditary mucosal syndromes, infections or preneoplastic/neoplastic processes. This differential diagnosis is best resolved in many cases by exfoliative cytology, interpreted in the context of clinical history and physical findings. The following report describes a case of white sponge nevus with typical clinical and cytologic findings, in which the diagnosis was confirmed by ultrastructural cytology. light microscopic cytology revealed parakeratotic cells and many cells containing dense eosinophilic intracytoplasmic inclusions. Electron micrographs of exfoliated cells demonstrated that these inclusions are composed of disordered aggregates of tonofilaments.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/7. nevus of ota with associated palatal involvement.The nevus of ota is a macular discoloration of the face which is most commonly found in the Japanese. The sclera is also often affected. The oral cavity is less commonly involved in the Japanese and is rarely affected in non-Orientals. The present case is only the seventh reported in a non-Oriental patient with clinical oral involvement and the first to illustrate the histopathologic features of an oral-lesion.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
5/7. cryosurgery for hemangiomas of the body surface and oral cavity.The indications for and limitations of cryosurgery for various types of hemangiomas on the body surface or in the intraoral region are reported based on our clinical experience. In our opinion, cryosurgery is not the method of choice in the management of hemangiomas but is useful under certain conditions, as with a localized cavernous under certain conditions, as with a localized cavernous hemangioma in the facial or intraoral region. It is also valuable for strawberry marks with bleeding or infection and may be acceptable for small port-wine stains; in the treatment of extensive port-wine stains, a resulting hypertrophic scar or depigmentation may present difficulties.- - - - - - - - - - ranking = 4keywords = oral cavity, cavity (Clic here for more details about this article) |
6/7. tissue expansion with endoscopy.tissue expansion is a time-honored technique in plastic surgery. However, while it is possible to rectify quite severe problems, the technique is not free of complications (e.g., extrusion) and, moreover, it can be a lengthy procedure, often taking months. endoscopy is increasingly being used in plastic surgery and has the advantage that large areas can be dissected using only small incisions. However, in endoscopic plastic surgery the main problem is the lack of an optical cavity. This means that special retractors are needed to keep skin and fat tissue lifted. This paper describes a technique for the placement of tissue expanders during endoscopy. Incisions are not made in the area that is to be expanded and, thus, there is no risk of extrusion and tissue expanders can be fully inflated intraoperatively. A further advantage is that the procedure reduces patient discomfort to a minimum.- - - - - - - - - - ranking = 0.019407659201319keywords = cavity (Clic here for more details about this article) |
7/7. Primary malignant melanoma of the oral cavity. Report of an unusual case.Primary malignant melanoma is only rarely found in the oral cavity (estimated at between 0.2 and 8 per cent of all melanomas) and occurs approximately four times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. A case is reported of a malignant melanoma in the mouth of a 74 year old male, which was originally diagnosed as reactive denture hyperplasia caused by a ill-fitting upper denture. Correction of the denture fault failed to stop the growth of the mass, which was therefore removed surgically. Histological examination revealed a melanin-producing tumour. A partial maxillectomy was performed and there was no evidence of recurrence over a three year follow-up period.- - - - - - - - - - ranking = 5keywords = oral cavity, cavity (Clic here for more details about this article) |
