1/43. Alveolar soft part sarcoma of the tongue: report of an unusual pattern in a child.A case of an unusual, primary alveolar soft part sarcoma of the tongue in a 3-year-old boy is presented. Alveolar soft part sarcoma is a rare malignant tumor that presents more frequently in the head and neck region of infants and children. To date, only six cases of lingual alveolar soft part sarcoma presenting in the first decade of life have been reported in the English literature. The patient has undergone surgical resection without adjuvant chemotherapy or radiation. Thus far, the patient does not manifest persistent or recurrent disease.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/43. Alveolar soft-part sarcoma in the oral cavity: report of a case.This case presents a rare tumor of the oral cavity--an alveolar soft-part sarcoma. Difficulties developed in the diagnosis, and therefore, consultations were required. Because of the radioresistant qualities of the lesion, wide surgical excision was performed. The patient's condition has been followed for 40 months without evidence of recurrence. The conclusion arrived at from review of the literature is that this is an indolent but malignant tumor and has so far proved to be 100% fatal. However, it may be 20 years before it proves fatal.- - - - - - - - - - ranking = 0.5keywords = alveolar (Clic here for more details about this article) |
3/43. Alveolar soft part sarcoma of the tongue.We report a case of alveolar soft part sarcoma--a rare malignancy that presented as a swelling at the base of the tongue in a 5-year-old child. Only about one-quarter of the few reported cases arise within the head and neck, the tongue and orbit being the favoured sites.- - - - - - - - - - ranking = 0.5keywords = alveolar (Clic here for more details about this article) |
4/43. Establishment of high and low metastasis cell lines derived from a human tongue squamous cell carcinoma.Malignant tumors are composed of cells with different phenotypic properties and only certain cell subpopulations present metastatic potential. The establishment of cell lines with high or low metastatic potential is necessary to investigate the molecular mechanisms of the metastatic process. However, human oral squamous cell carcinoma (SCC) cell lines that are suitable for the above investigation are scarce. High and low metastatic cells were obtained from a primary lesion of a patient with tongue carcinoma who had not received any therapy. Two distinct cell lines were selected, UM1 with a scattered growth pattern and loose cell-cell adhesion, and UM2 with a colony-formed growth pattern and firm cell-cell adhesion. The expression of E-cadherin in UM1 was clearly lower than that in UM2. UM1 exhibited a higher motility, invasive and metastatic activity than UM2 in vivo and in vitro. A low invasive and a metastatic oral SCC cell line, useful to investigate invasion and metastasis mechanisms, have been established.- - - - - - - - - - ranking = 0.00077815956740789keywords = process (Clic here for more details about this article) |
5/43. Alveolar soft part sarcoma of the tongue. Report of a case.The clinicopathologic, immunohistological, and ultrastructural features of an alveolar soft part sarcoma of the tongue occurring in a 2-year-old girl are described. A primary alveolar soft part sarcoma arising in the dorsum part of the tongue is quite rare. There has been no recurrence or metastasis as of 7 years postoperatively.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
6/43. Proliferative myositis arising in the tongue.We describe a rare case of proliferative myositis affecting the lateral border of the tongue. The site of the lesion and its gross pathological presentation were highly suggestive of a malignant process. Subsequent biopsy and characteristic histological appearance led to the diagnosis of this benign condition. This is the first reported case of a painful presentation of proliferative myositis involving the tongue. This report serves to remind the head and neck surgeon of the need to obtain histological diagnosis of malignancy before embarking upon radical surgical treatment. We recommend careful follow-up to ensure complete resolution of the lesion.- - - - - - - - - - ranking = 0.00077815956740789keywords = process (Clic here for more details about this article) |
7/43. Multiple congenital epulis of the alveolar ridge and tongue.Congenital granular cell tumor, also known as congenital epulis, is a very rare lesion seen in newborns. The typical presentation is a solitary nodule occurring on the gingiva of the anterior alveolar ridge of either jaw. Multiple-site involvement is seen very seldom but has been noted on the same or different alveolar ridges. However, tongue involvement is exceptional, and there have been only three cases reported involving both the alveolus and the tongue. A female newborn with multiple congenital epulis on the mandibular alveolar ridge and tongue is presented, and her preferred treatment and histopathological diagnosis are discussed.- - - - - - - - - - ranking = 3.5keywords = alveolar (Clic here for more details about this article) |
8/43. Well-differentiated liposarcoma of the tongue.Intraoral liposarcomas are rare, with most reported cases being of the myxoid histological type. We present a well-differentiated liposarcoma of the tongue, in a 65-year-old man. The tumour presented lipoblasts in various stages of differentiation, lipocytes in different sizes and shapes, mesenchymal and signet-ring cells. Lipoma, spindle-cell lipoma, myxoma, hibernoma, angiolipoma, fibrolipoma, pseudosarcomatous faciitis and malignant hysticytoma were considered in the diagnosis process. The patient was treated surgically and so far is free of disease.- - - - - - - - - - ranking = 0.00077815956740789keywords = process (Clic here for more details about this article) |
9/43. radiotherapy prostheses.The orofacial region performs the essential functions of mastication and speech, as well as that of appearance, which for better or worse evokes an instant and instinctive response in other people. In this region, tissue loss caused by surgical resection of a malignant tumor has a tremendous negative impact on the patient's quality of life, with deep mental and psychological repercussions. Therefore, from the standpoint of preserving form and function, radiotherapy has a major role to play in the treatment of malignant tumors in the orofacial region. That said, important organs, such as sensory organs, are present in close proximity to each other in this small region. During the irradiation process, therefore, it is important to ensure that the lesion is sufficiently irradiated while simultaneously protecting the surrounding normal tissue. In certain cases of radiotherapy of malignant tumors of the orofacial region, the use of radiotherapy prostheses can help to satisfy a basic principle of radiotherapy: that of delivering a lethal dose to the tumor while minimizing irradiation to normal tissue. In recent years, medical and dental experts have taken a team approach to creating and employing a variety of radiotherapy prostheses, working towards improving the treatment record for malignant tumors as well as reducing complications in surrounding normal tissue. As a result, patients treated with radiotherapy prostheses are now able to receive post-radiotherapy prosthodontic treatment in a dramatically safer and more rapid manner. It is clear that radiotherapy prostheses contribute significantly to the improvement of these patients' quality of life.- - - - - - - - - - ranking = 0.00077815956740789keywords = process (Clic here for more details about this article) |
10/43. Prosthetic management of a total glossectomy defect after free flap reconstruction in an edentulous patient: a clinical report.Total glossectomy with surgical reconstruction can result in a significantly altered mandibular arch anatomy. In edentulous patients, lingual vestibules along with the mandibular alveolar ridge can be obliterated. With the absence of lower anterior dentition, support of the lower lip is lost and traction from surgical closure can cause the lower lip to collapse into the oral cavity. This report describes the prosthetic treatment of an edentulous total glossectomy patient with an unconventional custom impression procedure to develop and record proper lower lip and cheek support. It also discusses some issues involved in the prosthetic management of the total glossectomy patient.- - - - - - - - - - ranking = 0.5keywords = alveolar (Clic here for more details about this article) |
