1/63. Fibrodysplasia ossificans progressiva and associated osteochondroma of the coronoid process in a child.The article reports the occurrence of osteochondroma in a fibrodysplasia ossificans progressiva patient. A 5-year-old boy presented with limited mouth opening and firm swelling of the right zygomatic complex area. The boy had bilateral hallux valgus of the great toes and heterotopic endochondral ossification of facial and neck regions. Associated osteochondroma of the coronoid process and aggressive heterotopic ossification of masticatory and neck muscles were found in response to traumatic injuries. Natural and clinical histories of fibrodysplasia ossificans progressiva were reviewed. An early diagnosis and avoidance of factors that aggravate ossification are key factors in reducing the expected degree of physical disabilities of patients. An early recognition of congenital skeletal deformities, early detection of abnormal ossification, and awareness of the disease by the involved physicians are important factors in the early diagnosis of the disease and in reducing any unnecessary trauma. Bone scintigrams and CT scans are effective noninvasive tools for an early detection of ossification and for monitoring the progression of the disease. Further investigation of its pathogenesis at a molecular level is important to understand better the nature of the disease and to develop an effective treatment protocol.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
2/63. A case of metastasizing pleomorphic adenoma.The pleomorphic adenoma is the most common benign salivary neoplasm. A case is presented in which a palatal pleomorphic adenoma seeded a metastasis in the medullary cavity of the anterior maxilla, apparently by hematogenous spread after surgical manipulation.- - - - - - - - - - ranking = 12.426214471874keywords = cavity (Clic here for more details about this article) |
3/63. Oral plasmablastic lymphoma in previously undiagnosed hiv disease.Non-Hodgkin's lymphoma is the second most common hiv-associated malignancy. This report details a case of the recently described entity plasmablastic lymphoma of the mouth in a patient who was later found to have severe hiv disease. The tumor manifested as a large ulcerated mass of the left maxillary alveolus, causing bony destruction and tooth mobility. Histologic examination of lesional tissue revealed a lymphoid tumor with a high proliferation rate containing lymphoplasmacytoid cells that were reactive to the plasma cell marker VS38c but not to CD20 or CD79a; these are features of the recently reported non-Hodgkin's lymphoma termed plasmablastic lymphoma. This is only the second report of an unusual tumor that has a predilection for the orofacial tissues.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
4/63. Polymorphous low-grade adenocarcinoma of the oral cavity.Polymorphous low-grade adenocarcinoma (PLGA) is a neoplasm arising most commonly within the minor salivary glands of the oral cavity. Not recognized as a distinct entity until 1983, PLGA was often misdiagnosed as adenoid cystic carcinoma or pleomorphic adenoma. PLGA is thought to be the second most common salivary gland tumor after mucoepidermoid carcinoma. Affecting individuals later in life, PLGA often presents as a firm, painless nodule that exhibits a locally aggressive, infiltrative pattern. Because of PLGA's slow growth rate and low rate of metastasis, differentiation from other disease entities is crucial for treatment modalities. The study presented here reviews three cases of PLGA, their treatment and follow-up.- - - - - - - - - - ranking = 1679.1224371092keywords = oral cavity, cavity (Clic here for more details about this article) |
5/63. Malignant odontogenic myxoma of the maxilla: case with cytogenetic confirmation.An odontogenic myxoma of the maxilla with an aggressive clinical course is presented. The tumour arose in a 53-year-old patient, recurred two times after extended maxillectomy and ultimately caused the patient's death by uncontrollable local disease with infiltration of the cranial cavity. Microscopically, the tumour showed histological features of a low grade malignant myxosarcoma with cellular areas, enhanced mitotic activity and nuclear pleomorphism. cytogenetic analysis revealed an unexpectedly aberrant hypertetraploid chromosome complement, that was considered as incompatible with the usual karyotypic patterns of benign tumours.- - - - - - - - - - ranking = 12.426214471874keywords = cavity (Clic here for more details about this article) |
6/63. Acinic cell carcinoma of the oral cavity.A rare case of acinic cell carcinoma of minor salivary gland origin within the oral cavity is reported in a 62-year-old woman. These tumors most commonly arise in the parotid gland and follow an insidious course requiring long-term follow-up. The gross and histologic features of the patient's tumor include pseudoencapsulation, mixed solid and acinar architecture, microcyst formation, and the presence of conspicuous diastase-fast and PAS-positive cytoplasmic granules, characteristic of lesions that have been called acinic cell carcinoma by a variety of authors. Surgical excision is the treatment of choice. However, following an incisional biopsy, the patient refused further surgical treatment and has remained clinically disease-free three years postoperatively.- - - - - - - - - - ranking = 1679.1224371092keywords = oral cavity, cavity (Clic here for more details about this article) |
7/63. Maxillofacial prosthetic rehabilitation of a midfacial defect complicated by microstomia: a clinical report.Severe limitation in the oral opening, though an uncommon clinical presentation, makes gaining access to the oral cavity difficult for any dental procedure. This article describes the maxillofacial prosthetic management of a patient with a midfacial defect complicated by postsurgical microstomia. Intraoral and extraoral prostheses restored the patient's speech, dental articulation, mastication, lip support, esthetics, and anterior oral seal.- - - - - - - - - - ranking = 335.82448742184keywords = oral cavity, cavity (Clic here for more details about this article) |
8/63. dermoid cyst of the maxillary sinus.Dermoid cysts are rare developmental teratomatous lesions composed of ectodermally derived stratified squamous epithelium and mesodermally derived skin adnexal structures. As part of the teratomatous lesion group, dermoid cysts are related to teratoid cysts, true teratomas, and epignathi. Although several theories have been postulated, the pathogenesis of dermoid cysts, and teratomatous lesions in general, is unclear. Most commonly affecting sites within the head and neck, dermoid cysts may be found in the frontotemporal/lateral brow area, central nasal area, oral cavity, lateral neck, and other sites. We present what is believed to be the first reported case arising within the maxillary sinus and briefly discuss the possible pathogenesis.- - - - - - - - - - ranking = 335.82448742184keywords = oral cavity, cavity (Clic here for more details about this article) |
9/63. Recurrent infection of a complex odontoma following eruption in the mouth.Odontomas are the most common odontogenic tumors, and are classified as either compound or complex lesions. Although its underlying etiology remains unclear, a number of factors appear to be involved (e.g., prior trauma). The lesions are generally diagnosed in the second decade of life, often in the context of routine dental X-ray examinations. A complex odontoma is described in a 22-year-old woman referring discomfort due to overinfection following its aperture into the oral cavity in the distal alveolar region of 2.6. Initial treatment consisted of antibiotics and antiinflammatory drugs. Computed axial tomography revealed a solid, irregular mass in the distal zone of the left maxilla, imprinting upon the region of the maxillary sinus on the same side. Surgical resection was performed, raising the alveolar mucosa and upper left vestibular fundus. The surgical piece contained the amorphous adenoma mass and the tooth 2.7.- - - - - - - - - - ranking = 339.82448742184keywords = oral cavity, cavity, mouth (Clic here for more details about this article) |
10/63. Reconstruction of total lower lip, labial commissure and palatomaxillary defect with composite island cheek flap.Functional and cosmetic restoration of total lower lip, labial commissure, and palatomaxillary defects can be achieved by using multiform flaps. The possibility of reconstruction of these areas with composite island cheek flap is presented. The flap was used in three patients who were surgically treated between 1993 and 1998. In one female patient, total lower lip and chin defect was restored with a small contralateral platysma muscle cutaneous flap. The functional and cosmetic result was achieved with composite island cheek flap. In the other two cases, reconstruction was performed without another flap. Composite island cheek flap is supplied with bloody by the facial artery and vein, and contains mucous membrane, muscle and skin of the cheek. In two cases, the flap was formed by the anterior part of the buccal muscle, and in the case with the reconstruction of labial commissure, the greater and lesser zygomatic muscles with levator muscle of the angle of mouth were used. By freeing the blood vessels from the surrounding structures, isolation and transsection of minor vessel branches allowed straightening of the tortuous main vessels. With this technique, excellent functional and satisfactory cosmetic results were achieved in a single act, with minimal morbidity for labial commissure, and total lower lip or palatomaxillary defect reconstruction.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
