1/158. 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.

2/158. 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.

3/158. 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.

4/158. 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.

5/158. 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.

6/158. 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.

7/158. 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.

8/158. fibrosarcoma of the trachea in a child: case report and review of the literature.

    We present a case of nearly total obstruction of the trachea in a 15-month-old boy suffering from tracheal fibrosarcoma. The diagnosis was confirmed on histological examination of a removed part of the tumor, with subsequent successful complete resection of tracheal fibrosarcoma. Follow-up to the age of 13 years showed complete recovery with normalization of respiratory functions. The diagnostic and therapeutic aspects of this case are discussed.

9/158. Tracheal neurilemmoma mimicking bronchial asthma--a dilemma of difficult diagnosis: case report.

    Tracheal tumors are often overlooked as a cause of pulmonary symptoms until they reach an advanced state. They are often presented with a prolonged cough and shortness of breath. Most tracheal tumors in adults are cancerous (80% to 90%). Benign tracheal tumors are rare in adult patients. A case history is presented of a 19-year-old patient with a rare tracheal neurilemmoma. He was treated as having bronchial asthma initially, but his signs and symptoms did not improve with traditional therapy. The possibility of the presence of an upper airway obstruction was not raised until the typical "inspiratory tubular sound" was heard. Flow-volume loop testing, bronchoscopy, and three-dimensional computed tomography (3-D CT) confirmed the diagnosis of upper airway obstruction caused by a tracheal tumor. Therefore, surgical intervention rather than bronchoscopic removal was performed without difficulty. The patient was leading a stable life 8 months after a surgical resection. The presence of an upper airway obstruction can be proven by flow-volume loop testing and 3-D CT. Further pathologic confirmation can be accomplished by bronchoscopy. High suspicion of an upper airway obstruction such as a tracheal lesion should be raised when bronchial asthma patients fail to respond to conventional treatment.

10/158. Primary tracheal schwannoma.

    We report a case of a primary tracheal schwannoma causing symptoms of airway obstruction in a 33-year-old man. bronchoscopy and computerized tomography demonstrated a polypoid intratracheal mass obstructing 90% of the lumen. Tracheal resection with primary anastomosis was performed. Histologic analysis revealed a benign neurogenic tumor of Schwann cell origin.
