1/46. brachytherapy using gold-198 foils in treatment of mouth tumors: case report.The authors presents a clinical case treated with brachytherapy performed with special mold of gold-198 disc, with the purpose of evaluating the distribution of radiation dose, the viability of manufacturing the radioactivity prosthesis and its operational cost. In despite of being only one case, we can conclude that the prosthesis with gold-198 foils can be manufactured in acrylic with thickness thinner than those ones with cylinder of cesium-137, resulting lower operational costs, besides permitting better distribution of radiation dose on the lesion.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/46. Uncontrolled central adenoid cystic carcinoma: case report.Central adenoid cystic carcinomas are rare malignancies that are believed to arise in ectopic salivary gland tissue within the maxilla or mandible. We describe the diagnosis and treatment of a central adenoid cystic carcinoma in a 54-year-old man, which we believe was a recurrence of an earlier growth that had not been completely excised. We also present a review of the literature.- - - - - - - - - - ranking = 87.953364294552keywords = mandible (Clic here for more details about this article) |
3/46. Central (intraosseous) adenoid cystic carcinoma of the mandible: report of a case with periapical involvement.Primary intraosseous salivary gland tumors are rare, with mucopidermoid carcinoma being the most frequent histotype. The authors present a case of adenoid cystic carcinoma, located in the mandibular incisor region, associated with pain. Endodontic treatment resulted in increased pain and progressive mandibular expansion. An apicoectomy was conducted, and an intraosseous adenoid cystic carcinoma was diagnosed at histological examination. The patient was treated by wide surgical resection, and is alive and well without recurrences or distant metastases 14 yr after the original diagnosis. The case presented herein calls attention to the preoperative clinical diagnosis of periapical lesions. Radiologically, focal sclerosing osteitis, cementoblastoma, cementifying and ossifying fibroma, periapical cemental dysplasia, complex odontoma, and calcifying epithelial odontogenic tumor should be considered in the differential diagnosis. In addition the unusual occurrence of salivary gland tumors in intraosseous location stresses the importance of systematic histological examination of any tissue sample obtained after endodontic procedures.- - - - - - - - - - ranking = 351.81345717821keywords = mandible (Clic here for more details about this article) |
4/46. Intracranial adenoid cystic carcinoma of suprasellar region.Adenoid cystic carcinoma (ACC) is a relatively common head and neck tumor which grows slowly but locally aggressive and prone to recurrence. ACC most commonly arises in the major and minor salivary glands. Some rare cases of intracranial ACC with an unknown primary site have been reported. The authors present the first case of primary intracranial ACC of the suprasellar region. A 34 year-old female presented with one month's duration of visual disturbance and galactorrhea. Magnetic resonance image (MRI) showed intra- and suprasellar mass mimicking a craniopharyngioma. There was no evidence of invasion from an extracranial site. The operative findings showed the mass existed under the arachnoid membrane and seemed to originate from the pituitary stalk. Pathological diagnosis was ACC. After the first operation, local recurrence and CSF dissemination to the lower clivus occurred within two months. recurrence repeatedly treated by Gamma knife radiosurgery 10 times and 4 times by surgery during a 3 year follow-up period. But total removal of the tumor at the first operation along with radiosurgery may control the lesion and prevent further recurrence.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
5/46. basal cell nevus syndrome concurrent with adenoid cystic carcinoma of salivary gland.basal cell nevus syndrome is a genetically determined disease characterized by 5 major manifestations (multiple basal cell carcinomas, jaw cysts, skeletal abnormalities, pits of the hands and feet, and ectopic calcification) and a variety of developmental anomalies. We present a case of basal cell nevus syndrome in which the patient had adenoid cystic carcinoma of the minor salivary glands develop in the soft palate resulting in distant pulmonary metastases. The patient died at the age of 44 years of respiratory complications. To our knowledge, this is the first simultaneous occurrence of basal cell nevus syndrome with adenoid cystic carcinoma of salivary gland.- - - - - - - - - - ranking = 4.7208399192522keywords = jaw (Clic here for more details about this article) |
6/46. Aspiration cytology of ameloblastic fibroma: a diagnostic challenge.Ameloblastic fibroma of the jaw is a rare, benign mixed odontogenic tumor, having little tendency for local invasion and a low recurrence rate. Cytologic distinction from ameloblastoma, ameloblastic fibrosarcoma, and intraosseous adenoid cystic carcinoma is necessary, in view of the different biologic behavior. A painful, slow-growing swelling of the jaw in a 5-yr-old child clinicoradiologically considered as a benign cystic lesion was aspirated. Sheets of small monomorphic epithelial cells with peripheral palisading by columnar cells were seen on cytology smears. The striking feature was central hyaline globules in some tubules. A cytologic possibility of adenomatoid odontogenic tumor was suggested. Histopathology, however, confirmed it to be an ameloblastic fibroma.- - - - - - - - - - ranking = 9.4416798385044keywords = jaw (Clic here for more details about this article) |
7/46. Adenoid cystic carcinoma of the breast.Adenoid cystic carcinoma of the breast is a rare neoplasm, with only 140 cases having been reported to date. Data on 123 of these cases are reviewed herein and another case is presented in detail. Several features distinguish this type of breast cancer from more typical histologic types and suggest that it may have a unique tumor behavior. The prognosis appears to be favorable and the incidence of axillary lymph node involvement is lower. Distant metastases are uncommon, but they tend to occur without prior lymph node involvement. This lack of prognostic significance for negative axillary lymph nodes underscores the need for other prognostic markers in this disease and suggests that axillary dissection can be eliminated in most cases. Similarities to typical breast cancer include the incidence of local recurrence and the lack of effect of surgical treatment on distant metastases and overall survival. These data suggest that breast-conserving treatment may be applicable to adenoid cystic carcinoma.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
8/46. A case of adenoid cystic carcinoma of the bronchus producing cancer-associated antigen, CA19-9.A 73-year-old male was admitted to Hyogo College of medicine Hospital for further evaluation of chest x-ray abnormalities. Chest roentgenogram taken at admission showed right lower lobe atelectasis and bronchoscopic examination revealed an endobronchial tumor obstructing the left lower lobe bronchus. The biopsy specimen showed cribriform adenoid cystic carcinoma. The serum CA19-9 level was markedly elevated at admission, leading to immunohistochemical analysis of the biopsy specimen. As a result, in the tumor, CA19-9 was positively stained. This is probably the first reported case of adenoid cystic carcinoma of the bronchus which produces CA19-9.- - - - - - - - - - ranking = 2keywords = lower (Clic here for more details about this article) |
9/46. Multiple linear cylindromas.We report a case of multiple cylindromas with a linear arrangement on the lower right extremity. The patient had more than 100 tumors, but the scalp was spared. Some tumors showed overlapping features with eccrine spiradenoma.

10/46. Primary pulmonary adenoid cystic carcinoma: report of a case diagnosed by fine-needle aspiration cytology.Adenoid cystic carcinoma of the lower respiratory tract is an uncommon tumor that can arise in the mainstem bronchus and often presents as an endobronchial mass lesion causing bronchial obstruction with post obstructive atelectasis and pneumonia. Exfoliative cytology is seldom useful in the diagnosis of primary bronchial adenoid cystic carcinoma, because these neoplasms usually have a submucosal location with often intact mucosa. Since most endobronchial adenoid cystic carcinomas are endoscopically visible, bronchoscope-guided fine-needle aspiration constitutes an excellent approach to establish a pathologic diagnosis. The fine-needle aspiration cytology of primary pulmonary adenoid cystic carcinoma has been rarely described. We report a case of primary adenoid cystic carcinoma of the lung having characteristic cytologic features and correlate with computed tomography, bronchoscopic, and histological findings. Bronchoscope-guided aspiration cytology provided a conclusive diagnosis of adenoid cystic carcinoma, which was further corroborated by histology in the pneumonectomy specimen. Diagn.
