Prenatal sonographic features of embryonal rhabdomyosarcoma. (1/187)
We describe a case of fetal rhabdomyosarcoma detected during the third trimester of pregnancy by prenatal sonography. At 33 weeks' gestation, sonography performed because of suspected polyhydramnios showed a solid mass of 120 x 54 mm arising from the anterior wall of the fetal thoracic cage. Another mass within the left maxillary area which originated from the left orbital floor was also detected. In the abdomen, there were multiple round masses in and around the liver. As the previous scan at 28 weeks had appeared normal, the multiple masses which became visible and enlarged rapidly in different locations led us to believe that there was fetal cancer. The most likely diagnosis was rhabdomyosarcoma (which was later confirmed), because it is the most prevalent soft-tissue tumor in children and may develop within or outside muscle anywhere in the body and at any age. Two other reported cases which were detected by prenatal ultrasound examination are also discussed. (+info)CT and MR imaging appearances of an extraosseous calcifying epithelial odontogenic tumor (Pindborg tumor). (2/187)
We herein report a rare case of extraosseous calcifying epithelial odontogenic tumor with local aggressive behavior. CT and MR imaging showed the distinctive appearances of this histologic entity. We briefly discuss the radiologic features of calcifying epithelial odontogenic tumor and the relevant literature. (+info)Bilateral hyperplasia of the mandibular coronoid processes associated with the nevoid basal cell carcinoma syndrome in an Italian boy. (3/187)
In this report we present a subject affected by nevoid basal cell carcinoma syndrome (NBCCS), showing also bilateral mandibular coronoid processes hyperplasia, a hitherto unreported association. Our observation of bilateral hyperplasia of the mandibular coronoid processes in a boy with NBCCS may prompt a retrospective and prospective review of other patients affected by this syndrome in order to establish if this anomaly is part of it. (+info)Ameloblastic fibroma of the anterior maxilla presenting as a complication of tooth eruption: a case report. (4/187)
Ameloblastic fibroma is a rare mixed odontogenic tumour, which is extremely uncommon in the anterior maxillary region. A case report is presented where failure of eruption of an upper central incisor was the presenting feature. (+info)The management of cervical lymph nodes in head and neck cencer. (5/187)
It is suggested that the last major improvement in the surgical treatment of head and neck cancer was Crile's description of radical neck dissection in 1906, and that modifications of this procedure, including extended surgery, have made little or no difference to survival rates. It is hoped that some means may soon be found of identifying those patients with head and neck cancer who do badly--the majority. As a start, it is proposed that patients with an antral carcinoma and a gland in the neck, and patients with hypopharyngeal carcinoma and bilateral neck glands should not be treated by surgery. A retrospective analysis is made of matched pairs drawn from a personal series, one patient in each pair having had a prophylactic neck dissection, and one having been submitted to a policy of 'wait and see'. The survival rate for patients undergoing prophylactic neck dissection was worse than that of the wait and see group; this difference was statistically significant. (+info)Intraosseous pleomorphic adenoma: case report and review of the literature. (6/187)
Pleomorphic adenoma is the most common neoplasm of the salivary glands, affecting mainly the parotid gland. The preferential intraoral site of this tumor is the palate. A case of a 31-year-old woman with an intraosseous pleomorphic adenoma located in the maxilla (left paramedian region), showing an approximate evolution of one year is reported. The present intraosseous case represents a rare location, with the tumor probably originating from glandular epithelial remnants captured during embryogenesis. In a review of the literature of 142 cases of intragnathic localization (24% in the maxilla) are identified. A slight predominance of women was observed (56%), with 55% of the patients being affected during the 5th to 7th decade of life. The tumors were malignant in 94% of the cases, with special predominance of mucoepidermoid carcinoma (65%). Intraosseous pleomorphic adenomas are rare, with the present patient being the 6th case reported in the literature and the second found in the maxilla. Mean age of the 5 previously reported cases was 58.8 years. (+info)3D-CT imaging processing for qualitative and quantitative analysis of maxillofacial cysts and tumors. (7/187)
The objective of this study was to evaluate spiral-computed tomography (3D-CT) images of 20 patients presenting with cysts and tumors in the maxillofacial complex, in order to compare the surface and volume techniques of image rendering. The qualitative and quantitative appraisal indicated that the volume technique allowed a more precise and accurate observation than the surface method. On the average, the measurements obtained by means of the 3D volume-rendering technique were 6.28% higher than those obtained by means of the surface method. The sensitivity of the 3D surface technique was lower than that of the 3D volume technique for all conditions stipulated in the diagnosis and evaluation of lesions. We concluded that the 3D-CT volume rendering technique was more reproducible and sensitive than the 3D-CT surface method, in the diagnosis, treatment planning and evaluation of maxillofacial lesions, especially those with intra-osseous involvement. (+info)Anterolateral thigh flap. (8/187)
A 64-year-old Japanese male had a squamous cell carcinoma (T4N1M0) in the left gingival and buccal mucosa, so a radical wide resection involving left radical neck dissection was performed. An anterolateral thigh flap measuring 15 x 8 cm was raised from the left thigh and transferred to the defect. The postoperative course was eventful. There was no postoperative flap necrosis, infection, not even a cervical fistula. (+info)
