Endobronchial tuberculosis is not as well-known to internists as tuberculosis involving the lung parenchyma. Five cases with this condition are reported to illustrate the varied clinical manifestations. The presenting features of the 5 cases were lobar or lung collapse, unresolved pneumonia, dyspnoea and stridor. Bronchostenosis developed in 2 patients many years following chemotherapy, while stenosis of the trachea developed in one patient during chemotherapy. In another patient, the tuberculous granulation tissue simulated a lung cancer at bronchoscopy. Diagnosis can be difficult as endobronchial tuberculosis can occur in the absence of chest X-ray abnormality and sputum smear may also be negative for acid fast bacilli (AFB). Therefore, bronchoscopy should be done when the condition is suspected in a patient who has unexplained cough, wheezing, dyspnoea or haemoptysis. The modalities of treatment for fibrostenosis of a large airway include surgical resection followed by anastomosis, balloon dilatation, laser photoresection or a combination of both procedures.

Ten cases of laryngotracheal invasion by well-differentiated thyroid cancer are described. All the patients were over 40 years of age, with a male preponderance of 4:1. A mass in the neck, stridor, and hemoptysis was the common symptom. Bronchoscopy done in six of ten patients revealed an intraluminal tumour in all. Radiographs of the neck showed invasion of the trachea in six patients. Surgery consisted of tracheostomy alone (three of ten), total thyroidectomy with laryngectomy (one of ten), circumferential resection of trachea (one of ten), and total thyroidectomy with tracheotomy and "shaving" of the intraluminal disease in five of ten patients. Adjuvant external radiation, radioiodine, or laser therapy was given when indicated. Of the ten patients, three died and seven survived. Five of seven were alive without disease for 2.5 years or more, and one had skull metastasis 2 years later but no local disease.

Thirteen adult patients underwent palliative Nd-YAG laser treatment for relief of severe dyspnea due to malignant endotracheal obstruction. Three of the 13 patients had underlying chronic airflow obstruction (CAO) due to diffuse obstructive pulmonary disease. Despite dyspnea, cough, wheezing, stridor and/or hemoptysis, the diagnosis was delayed because of a normal chest roentgenogram in eight patients and nondiagnostic pulmonary function studies (including maximal expiratory and inspiratory flow-volume loops) in all three patients with CAO and in four of ten patients without CAO. The location of the tumor was extrathoracic in two patients, including one with CAO; intrathoracic in seven patients, including two with CAO; and combined extra- and intrathoracic in four. Tracheal diameter increased from 3.5 +/- 1.0 mm before, and to 9.8 +/- 2.0 mm after single or multiple laser treatments. Increased patency of the trachea after laser surgery was associated with improvement in expiratory and/or inspiratory flow rates and with symptomatic relief in all patients which persisted for 14.1 +/- 8.7 months (range four to 48 months). These results indicate that severe symptomatic narrowing of the extra- and/or intrathoracic trachea to a diameter of 2 to 5 mm may not be detected by conventional chest radiography or even by sensitive physiologic tests, especially in patients with underlying CAO. The resultant delay in diagnosis defers possible relief of disabling symptoms with palliative therapy, including Nd-YAG laser photocoagulation.

Pulmonary KS may occur in up to 20 to 25 per cent of patients with cutaneous KS. The presenting symptoms of pulmonary KS are indistinguishable from those of opportunistic pathogens that cause pneumonia. It most frequently presents with the symptoms of cough or dyspnea; however, fever, hemoptysis, and stridor have been reported to occur secondary to pulmonary KS. Roentgenographically, pulmonary KS may present as diffuse infiltrates, nodal disease, and/or pleural effusions. The diagnosis is established by a characteristic histologic pattern obtained from large pieces of tissue, that is, from open lung biopsy or autopsy rather than from transbronchial biopsy. No effective therapy for pulmonary KS exists; however, short-term palliation may be achieved with radiotherapy or combination chemotherapy. In a patient with known pulmonary KS who develops either new or changing symptoms or new roentgenographic findings, an attempt should be made to rule out an associated infectious process.

Thyroid tumors may involve the airway. Eight patients with such invasion are reported; five with invasion of the larynx and three of the trachea. The symptoms varied: five of the eight patients had stridor and hemoptysis, one had hoarseness, and two had no symptoms at all. Endoscopic and radiologic examinations were performed in all patients including computed tomography in six. Six patients underwent total thyroidectomy and two patients, one with paraganglioma and one with hemangiopericytoma, had a hemithyroidectomy. Three patients had a total laryngectomy, one a partial laryngectomy and one a laryngofissure procedure. Tracheal resection was performed in two patients and one had laser excision of the endotracheal tumor involvement. Three patients received postoperative external irradiation. Six of the eight patients are alive with follow-up of 39 to 85 months.

Pulmonary Kaposi's sarcoma related to the acquired immune deficiency syndrome (AIDS) has not been well characterized. To define the clinical, radiographic, and pathologic features of this entity, 11 autopsy-proved cases of pulmonary Kaposi's sarcoma were reviewed. The most common clinical symptoms were dyspnea and cough, but hemoptysis and stridor were also found. Nodular infiltrates and pleural effusions were the most commonly found radiographic abnormalities. Pulmonary function tests were sensitive in detecting the pulmonary abnormalities due to Kaposi's sarcoma. A low diffusion capacity, lack of arterial desaturation with exercise, and obstruction to airflow were suggestive of pulmonary involvement with this malignancy. Although endobronchial Kaposi's sarcoma was visualized at bronchoscopy as cherry-red, slightly raised lesions, bronchial biopsy specimens always showed no abnormalities. Transbronchial brushings and biopsy specimens and analysis of pleural fluid were also not helpful in establishing a diagnosis. In the seven subjects with extensive parenchymal Kaposi's sarcoma at autopsy, the pleura was always involved. Eight subjects had involvement of the tracheobronchial tree. In all of the subjects, pulmonary Kaposi's sarcoma was a significant cause of morbidity, and in three of 11 subjects (27 percent) it was the direct cause of death.

Synovial sarcoma arises most commonly in the lower extremity, particularly in the region of the lower thigh and knee. Yet the occurrence of thus mesenchymal neoplasm in the head and neck area has been convincingly documented, albeit confined almost exclusively to cervical and parapharyngeal sites. Therefore, in view of its rarity in the head and neck, we analyzed a group of 11 synovial sarcomas arising in the orofacial region. The series comprised nine men (82%) and two women (18%). In common with synovial sarcoma at more conventional sites, this is a disease of young adults: ages ranged from 16-49 years (median, 34 years). Topographically, two subsets were delineated, a more common facial group with eight cases (four cheek, two parotid region, one infraorbital, one submental), all arising as gradually enlarging, usually nontender, solitary tumors; and three intraoral ones (two tonsillar, one lingual), two of which were polypoid and one was an exophytic tonsillar mass which presented with hemoptysis and stridor. Follow-up data, obtained for nine patients (range, 1.3-15.0 years), disclosed three (33%) tumor-related deaths, all belonging to the facial group. Treatment, difficult to significantly correlate with survival in this small series, varied from surgical excision alone to a multimodality approach including both irradiation and chemotherapy. Histologically, all the neoplasms revealed characteristic biphasic features, predominantly fibrosarcomatous in one, but, more typically, showing epithelial clefts and/or pseudoacinar spaces in the others. Differential diagnosis, depending on the proportion of the biphasic components, ranged from spindle cell mesenchymal neoplasms to various adenocarcinomas, including those arising in mixed tumors of salivary gland.

Although the availability of flexible fiberoptic bronchoscopy (FFB) has been a major advance in adult pulmonary medicine, the role of FFB in pediatrics has remained less well defined. Therefore, a two-year retrospective study was undertaken to determine the indications for FFB in 95 pediatric patients (mean age, 6.9 years) who underwent 129 FFB procedures. Indications for FFB included stridor (41/129), abnormal chest roentgenogram (38/129), airway evaluation in patients with tracheostomy (13/129), airway obstruction (11/129), hoarseness (9/129), recurrent pneumonia (7/129), chronic cough (4/129), failed extubation (3/129), tracheal injury (2/129), and hemoptysis (1/129). Overall, a specific diagnosis was made in 88% of cases, of which 48% involved a lower airway disorder. A minor complication rate of 2% was observed with no major complications.

We have reported on a 43 years old woman patient, who had fallen ill with an extremely seldom carcinoid tumor arising in the trachea histologically confirmed. Our observations of this woman-patient had been compared with those of 14 patients known from the Anglo-American literature upto 1978. In regard to one French and one Russian collective statistics altogether we come to 24 cases of trachea carcinoids documented in the literature. These are the main symptoms: dyspnea, wheezing, hemoptysis and stridor. Radiation tried at the inoperable patient has proved as ineffective. Today operation seems to be the chosen therapy.

In April 1988 the Christie Hospital started using the microSelectron-HDR machine to deliver intraluminal radiotherapy (ILT) to inoperable bronchial carcinomas causing symptoms due to endobronchial disease. Results of treatment in the first 406 patients with primary non-small-cell carcinoma are presented. Three main categories of patient were defined. Category 1 consisted of 324 patients (79.8%) who were previously unirradiated and received a single fraction of ILT as their primary treatment, mostly to a dose of 1500 cGy (76%) or 2000 cGy (23%) at 1 cm from the centre of the iridium-192 treatment source. The percentage of these patients whose symptoms or signs were improved at 6 weeks following ILT were as follows: stridor 92%, haemoptysis 88%, cough 62%, dyspnoea, 60%, pain, 50% and pulmonary collapse, 46%. Approximately two-thirds of these patients (67.3%) derived long lasting palliation and required no further treatment during their lifetime. The other third of patients needed subsequent treatment at some stage because of recurrence of their symptoms and in this situation external beam radiotherapy (EB) or a repeat ILT treatment was effectively utilised. Category 2 consisted of 65 patients (16%) who had previously received EB but required ILT when their tumour recurred. At 6 weeks post-ILT levels of symptom palliation were broadly similar to those obtained if ILT was used in previously unirradiated individuals, although the improvement was not so well sustained with time and only 7% showed improvement in pulmonary collapse at 6 weeks. Category 3 consisted of 17 patients (4.2%) in whom ILT was used concurrently with EB as a combined initial treatment. Similar levels of palliation were seen when compared with patients who received a single ILT treatment only. Overall, ILT was well tolerated in terms of early and late morbidity. In conclusion, the efficiency of a single ILT treatment in palliating symptoms due to endobronchial tumour in previously unirradiated individuals is comparable with that reported in series where treatment for advanced lung cancer combines a prolonged course of EB concurrently with several ILT treatments.
