1/98. 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.

2/98. 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.

3/98. 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.

4/98. 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.

5/98. 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.

6/98. 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.

7/98. Laser resection of a pedunculated tracheal adenoma.

    We report a case of tracheal adenoma presenting as hemoptysis and reversible airflow obstruction in an ex-smoker. A questionable defect in the tracheal air shadow on a posteroanterior chest radiograph was shown on CT to be a pedunculated, mid-tracheal tumor. Two-stage bronchoscopic laser resection resulted in an apparently normal tracheal mucosa. Results of postresection spirometry were normal.

8/98. 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.

9/98. Airway stenting for tracheal stenosis.

    patients with upper airway obstruction from malignant disease are difficult to manage. A 62 year old patient presented with stridor and was found to have an upper tracheal tumour. bronchoscopy, dilatation and stenting were performed successfully. The techniques and indications for the use of dynamic airway stent are discussed.

10/98. Primary tracheal mucosa-associated lymphoid tissue lymphoma accompanying lung cancer. Common tumorigenesis or coincidental coexistence?

    We report a 67-year-old patient with coexistent tracheal non-Hodgkin's lymphoma and lung cancer the first case, to our knowledge, of this concomitant incidence in the literature. Chest radiography showed a mass in the right lung and pulmonary fibrosis. biopsy of the unanticipated tracheal irregularity revealed non-Hodgkin's lymphoma, compatible with mucosa-associated lymphoid tissue lymphoma. After right upper lobectomy, chemotherapy for non-Hodgkin's lymphoma was conducted, but the patient died 11 months postoperatively of pulmonary fibrosis. pulmonary fibrosis was suspected of having progressed from drug-induced pneumonitis caused by anticancer drugs. A common tumorigenetic factor may thus exist between tracheobronchial mucosa-associated lymphoid tissue lymphoma and lung cancer.
