1/437. 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. ( info)

2/437. The present status of bronchoscopic Nd:YAG laser.

    In japan, the first bronchoscopic Nd:YAG laser applied clinically was performed in our institute 10 years ago, and based on this decade of experience, the indications, effectiveness, and limitations were studied. Between 1980 and 1989, a total of 202 cases were treated by Nd:YAG laser in our institute. Among them, 94 (46.5%) cases were primary lung cancers, 10 (5.0%) cases were primary tracheal malignancies, 56 (27.7%) cases were metastatic tracheal tumors, 6 (3.0%) cases were benign tracheal tumors, and 36 (17.8%) cases were nontumorous tracheal lesions. The indications for Nd:YAG laser therapy were defined as emergency widening of airway, curative treatment, reduction of tumor size, nontumorous benign lesions, and hemostasis. The desired therapeutic effects were obtained in 55/58 (94.8%) for emergency airway widening, 22/27 (81.5%) for curative treatment, 69/88 (78.4%) for reduction of tumor size, and 48/68 (70.6%) for nontumorous benign lesions. While performing Nd:YAG laser treatment, some limitations, such as poor residual pulmonary function, tumor size, tumor depth, cartilage structure, granulation, and stricture length, were encountered. Since bronchoscopic Nd:YAG laser treatment has become a well-established therapeutic modality for tracheobroncheal lesions, areas to be addressed in the future are the training of bronchoscopic laser therapists and research on the extension of applications. To increase the range of clinical applications, it is hoped that makers of laser systems will provide tunable wavelength machines at reduced cost. ( info)

3/437. Bronchoscopic therapy for mucosa-associated lymphoid tissue lymphoma of the trachea.

    The tracheal tumor of a 74-year-old female was detected on bronchoscopy and histologically diagnosed as mucosa-associated lymphoid tissue (MALT) lymphoma. We successfully treated the tumor with endoscopic neodyminum-yttruim-aluminium-garnet (Nd-YAG) laser photoresection followed by local ethanol injection. This is the first case in which tracheal MALT lymphoma was successfully treated with bronchoscopy. Bronchoscopic therapy seems to be one of the most valuable strategies for treatment of MALT lymphomas of the central airway. ( info)

4/437. Solitary plasmacytoma of the larynx and upper trachea associated with systemic lupus erythematosus.

    Solitary plasmacytoma rarely involves the larynx and trachea. This tumor caused severe laryngeal and tracheal obstruction in an adolescent female with systemic lupus erythematosus of nine years' duration. Her systemic disease had been in remission at the time she developed symptoms of laryngeal and tracheal obstruction by plasmacytoma invasion. A complete survey failed to reveal any other focus of tumor. Because steroid therapy failed to clear the plasma cell infiltrate, she was treated with irradiation after the tumor was surgically debulked endoscopically. Postirradiation biopsy showed no evidence of tumor, but the patient continued to experience moderate airway obstruction from fibrosis in the irradiated trachea. The patient has been followed, and is free of disease nine years after establishing the diagnosis. ( info)

5/437. 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. ( info)

6/437. life-threatening tracheal metastasis complicating ovarian cancer--a case report.

    BACKGROUND: Tracheal metastasis is a rare manifestation of recurrent ovarian cancer. CASE: We describe tracheal metastasis causing increasing respiratory distress in a patient with progressive stage IIIc undifferentiated serous-papillary cancer involving the peritoneum and pleura and the retroperitoneal, diaphragmatic, parahilar, mediastinal, pretracheal, paratracheal, and supraclavicular lymph nodes. The situation necessitated rapid endoscopic laser ablation. CONCLUSION: Malignant tracheal obstruction should be considered in the differential diagnosis of patients with advanced ovarian cancer and respiratory distress. ( info)

7/437. 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. ( info)

8/437. 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. ( info)

9/437. Malignant fibrous histiocytoma of the trachea.

    Primary tracheal sarcomas are rare. Only 23 cases have previously been reported in the English literature. The present case describes a 72-year-old woman with a malignant fibrous histiocytoma of the trachea. She underwent an endoscopic resection followed by radiotherapy and is well at 12 months follow up. Other cases are reviewed. Tracheal resection is the standard care. However, local resection with postoperative radiotherapy remains an option. Adjuvant chemotherapy may improve local control. Long-term survival has been documented. ( info)

10/437. Bronchial capillary hemangioma in adults.

    Two cases with capillary hemangioma of the trachea and the left upper lobe bronchus are presented. The adult patients were referred to the hospital because of hemoptysis and cough. The chest radiographs were normal in both cases. The bronchoscopic examination revealed circumscribed lesions with a capillarized surface protruding into the lumen of the trachea and the left upper lobe bronchus, respectively. The lesions were excised in toto with flexible bronchoscopic forceps. The specimens contained typical capillary hemangiomas without any signs of malignancy. Capillary hemangioma in the bronchial tree is an extremely rare benign lesion in adults. Nevertheless, it should be considered as a possible cause of hemoptysis and cough. ( info)
