1/139. mucoepidermoid tumor of trachea.Mucoepidermoid carcinoma of the trachea is rare. Its occurence in a 14-year-old boy is reported here. This case illustrates the typical course of tracheal tumors with clinical manifestations of cough, wheezing, and hemoptysis, the intially reported normal chest roentgenogram, and the common failure to diagnose tracheal tumor for several months. Early use of tomographic studies and bronchoscopic examination in any person with recent onset of airway obstruction unresponsive to bronchodilator therapy is recommended.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/139. Successful resection of endotracheal papillary adenocarcinoma by endoscopic electrosurgery using a new snare: report of a case.We report herein the rare case of a patient with endotracheal papillary adenocarcinoma of the goblet cell type. The tumor existed in the upper trachea, obstructing 95% of the airway, and prompt palliation was required. Endotracheal polypectomy was successfully performed in this patient using electrosurgery with a new snare designed for the respiratory tract. The procedure took only a few minutes and the dyspnea was relieved promptly without any complications. The alternative techniques for palliation of bronchial stenosis are also discussed.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
3/139. Oncocytic mucoepidermoid carcinoma of the trachea.We report a rare case of an oncocytic mucoepidermoid carcinoma of the trachea, which presented in a 78-year-old woman with hemoptysis. Oncocytic cells comprised the majority of this low-grade lesion and demonstrated granular cytoplasmic phosphotungstic acid-hematoxylin staining as well as strong immunohistochemical reactivity to antimitochondrial antibody. Most tracheobronchial tumors with oncocytic change are carcinoid tumors. To our knowledge, this is the first oncocytic mucoepidermoid carcinoma of the trachea reported. This diagnosis was facilitated by histochemical and immunohistochemical studies.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |
4/139. Tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.Ectopic thyroid tissue within the submucosa of the trachea is a rare cause of upper airway obstruction. Primary neoplasms arising from such thyroid nests are rare. This report describes a case of tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
5/139. Recurrent juvenile-onset laryngotracheal papillomatosis with transformation to squamous cell carcinoma of the lung.A 47-year-old female patient with recurrent juvenile-onset laryngotracheal papillomatosis for 27 years had multiple bilateral pulmonary lesions, the largest of which was a well-differentiated squamous cell carcinoma. This case is unique because the malignant transformation occurred in a nonirradiated, nonsmoking patient.- - - - - - - - - - ranking = 5keywords = carcinoma (Clic here for more details about this article) |
6/139. Successful primary radiation therapy of adenoid cystic carcinoma of the lung.Adenoid cystic carcinoma is a distinctive malignant neoplasm generally arising from minor salivary glands, that arises infrequently as a primary tumor in the lung. Surgery has been considered the primary treatment, with radiotherapy generally utilized as adjuvant or palliative treatment. We report a patient in whom primary radiotherapy was sucessfully applied to treat adenoid cystic carcinoma involving the distal trachea, carina, and both main stem bronchi. A total dose of 66 Gy was delivered in 2-Gy fractions over a 7-week period. Clinically and histologically complete remission was achieved without evidence of disease during a 27-month follow up.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |

8/139. Mucoepidermoid carcinoma of the trachea with airway hyperresponsiveness.We report a case of mucoepidermoid carcinoma of the trachea in a 23-year-old pregnant female in her 39th week. The patient had cough and wheezing in the early morning for 9 months before admission. No abnormalities were detected on a chest roentgenogram. At Caesarean section, fiberscopy revealed a polypoid lesion narrowing the trachea. The pathologic diagnosis made from the biopsy specimen obtained was low-grade mucoepidermoid carcinoma and the lesion was resected. Airway hyperresponsiveness was shown before resection with airflow limitation, however, airway reactivity and airflow limitation improved 1 year after resection.- - - - - - - - - - ranking = 6keywords = carcinoma (Clic here for more details about this article) |
9/139. Bronchoscopic cryotherapy: preliminary experience.Our preliminary experience with the bronchoscopic application of cryotherapy using rapid decompression of liquid nitrous oxide as cooling agent is reported. Seventeen applications through rigid bronchoscopy in twelve patients were performed. A single cryotherapy session was successful in the debulking of obstructive malignant lesions of the central airways in five patients (four non-small cell carcinoma, one renal cell cancer metastasis), and in the treatment of a capillary haemangioma (one patient). Two sessions were successful in the treatment of a metastatic melanoma (one patient) and benign granulation tissue (one patient). cryotherapy was also successful in the treatment of early bronchial cancer (carcinoma in situ) in four patients, requiring repetitive sessions in two. There were no complications or side-effects. These preliminary findings confirm the safety and efficacy of bronchoscopic cryotherapy in a variety of airway lesions.- - - - - - - - - - ranking = 2.0104204063498keywords = carcinoma, small cell (Clic here for more details about this article) |
10/139. Metastatic carcinoma (endometrial adenoacanthoma) to the trachea. Report of a successful resection and primary anastomosis.The first case report of an adenoacanthoma of the endometrium with metastasis to the trachea is presented. Successful resection with primary anastomosis was done, followed by external radiotherapy. The patient has been followed for 3 years to date with no evidence of recurrence. A brief discussion of this tumor is given.- - - - - - - - - - ranking = 4keywords = carcinoma (Clic here for more details about this article) |
