Three cases illustrate the principal clinical and roentgenographic varieties of granular cell myoblastoma (GCM) of the lung. The vast majority are small benign intrabronchial tumors without roentgenographic findings. These remain asymptomatic and are detected accidentally at autopsy, surgery, or bronchoscopy (Case III). Larger obstructing lesions (Case I) cause focal atelectasis or pneumonitis, leading to cough, expectoration, and hemoptysis. Hilar enlargement from reactive lymph node hyperplasia is common. Clinically and roentgenographically these are indistinguishable from bronchial adenomas. Least often the tumor extends entirely extrabronchially (Case II) presenting as a parahilar parenchymal asymptomatic nodule, simulating a granuloma, hamartoma, arteriovenous malformation or a neoplastic nodule.

Granular cell myoblastoma of the bronchus is rare. Two patients are described, bringing the total reported to 44. Review of the literature shows that cough, chest pain, hemoptysis, and wheezing are frequent presenting symptoms and that distal atelectasis and recurrent or persistent pneumonitis are common roentgenographic findings. Though the histogenesis of this tumor remains controversial, most pathologists now believe that the cells have a neurogenic origin. Adequate open surgical resection is the treatment of choice.

Twenty-four patients with bronchial adenoma seen over a 20-year period are reviewed. Follow-up data was available in all patients. They included 19 with carcinoid, 2 with adenoid-cystic carcinoma, and 3 with muco-epidermoid carcinoma. Recurrent pulmonary infection, cough and hemoptysis were the most common clinical manifestations. Surgical resection was performed in all but one patient, who was treated by irradiation; bronchoplastic and conservative resectional procedures were used in 5 patients with carcinoid adenoma. Carcinoid tumors are considered to be very slowly-growing malignant neoplasms that sometimes give rise to metastases to regional lymph nodes. Such metastases were present in only one patient. All patients are alive and well. Adenoid-cystic carcinoma is a more aggressive tumor with a tendency to recur. Much of the difficulty in its treatment is due to its close proximity to the bifurcation of the trachea. One patient was operated upon three times for local recurrences and ultimately died from respiratory failure after the third operation. The other patient received radiation therapy with cobalt and is well, without recurrence, 3 years after the treatment. The 3 muco-epidermoid carcinomas were histologically similar to such tumors of salivary glands but behaved clinically like highly malignant tumors, no patients surviving 8 months after resection. The term bronchial adenoma is a misnomer. The neoplasms grouped under this heading should be called carcinoid adenoma, adenoid-cystic carcinoma, and muco-epidermoid carcinoma and considered as separate entities, since the ultimate course and prognosis is definitely different.

Thirteen histologically proven cases of bronchial carcinoid from the literature and eight cases from the Armed Forces Tumor Registry, all under 20 yr of age, are presented. Hemoptysis, cough, and pneumonia were the most frequent presenting complaints. Bronchoscopy defined the lesion in all 16 cases so studied. Gross and microscopic pathology is briefly described, and treatment in these cases outlined. A good long-term prognosis can be expected, except in those cases with a long delay in diagnosis.

Ten patients developed pulmonary fibrosis after bischloroethylnitrosourea (BCNU) therapy for malignancy. This was lethal in seven patients, four of whom had no evidence of tumor at autopsy. Presenting symptoms were either the insidious onset of cough and dyspnea or the sudden onset of respiratory failure. Physical findings were unremarkable. Chest roentgenogram usually showed interstitial infiltrates. Pulmonary function studies showed resting hypoxia with diffusion and restrictive defects. This complication of therapy does not appear to be dose related and may be made more likely by the concomitant administration of cyclophosphamide. Prednisone therapy did not benefit most patients. The literature and the implications of the use of BCNU alone or in combination are reviewed.

Twenty-one cases of carcinomatous lymphangitis of the lung are reported. In diagnosing them clinical, roentgenologic, and histopathologic criteria were used and the clinical, roentgenologic and evolutive findins were considered in order to emphasize the origin of the primitive neoplasm. From this point of view the principal ones turned out to be carcinomas of the breast, stomach, and lung. The absence of carcinoma of the thyroid gland as a source of pulmonary lymphangitis carcinomatosa must be pointed out. The higher incidence of this condition in older people and the clear predominance in the female sex are stressed. From a clinical standpoint the most important data were the existence of cough and dyspnea, which are often associated with the commom presence of enlarged left supraclavicular or axillary lymph nodes. There was a predominant pure interstitial pattern (the most common feature was the presence of Kerley's A or B lines), sometimes coexisting with alveolar impairment and very often with accompanying pleural effusion. The mean survival rate was 2 months, with a maximum of 7 months and a minimum of 3 days. The results of the present series were compared with those of the literature and the most significant and constant fact in both instances was that two thirds of the cases of pulmonary lymphangitis carcinomatosa had their origin in neoplasms of the breast, stomach, and lung.

A new era dawned in 1940 when Batson published the theory that the vertebral venous system plays an important role in cancer carriage. He emphasized that this route comes into play with any natural movement such as coughing. Now, cough is a prominent feature of lung cancer. Therefore, this tumor is optimally positioned for utilizing the vertebral venous route of spread. However, when three major distribution patterns of lung cancer are examined critically, expectations from Batson's theory are not confirmed. If this paradox is recognized and explained, the prospects for solving the mysteries of human cancer metastasis will probably improve.

In a prospective study of 6,027 older men screened every six months for ten years by means of chest photofluorograms and questionnaires regarding symptoms, 121 developed lung cancer after the first examination. Eighty-five men with lung cancer had the opportunity to be screened eight times before the tumor was detected by chest x-ray film, but only 33 actually reported that often. These 33 men were compared with matched controls for symptoms before the neoplasm was detected radiologically. The common symptoms of expectoration and chronic cough showed a significant increase in frequency over time in the cases of cancer, while only expectoration showed a slight increase in the controls. Uncommon symptoms more suggestive of lung cancer (hemoptysis and worsening cough) occurred in only four men prior to detection of cancer. Symptoms are seldom useful in the detection of occult lung cancer, but the appearance of expectoration and chronic cough in older male smokers should raise a suspicion of this disease.

Seventy-six patients with pleural mesothelioma were seen at Memorial Hospital from 1939 to 1972. There were 10 with benign and 66 with malignant mesotheliomas. The latter were histologically divided into 39 epithelial and 27 fibrosarcomatous types. Main symptoms were chest pain, dyspnea, and cough. Most of the patients with malignant disease had clinical and radiologic evidence of effusion with or without an intrathoracic mass. Thirty-seven patients had primary untreated mesothelioma and 29 patients had disease that had previously been treated elsewhere. Treatment at Memorial Hospital consisted of surgery, with or without radiation therapy, and supplemental chemotherapy. Survival was related to extent of disease and to treatment. In patients with epithelial mesothelioma confined to the hemithorax, resection was associated with a median survival of 21 months. When irradiation was the primary treatment, the median survival was 8 months. In fibrosarcomatous mesotherlioma, the median survival with resection was 11 months and with radiation, 9 months. Median survival in patients with advanced or recurrent disease was 3 to 6 months. It is concluded that epithelial mesotherlioma with diffused pleural involvement continues to carry a grave prognosis. Better survival is obtained where pleurectomy with resection of the bulk of the tumor is combined with external irradiation and systemic chemotherapy. In fibrosarcomatous mesothelioma, complete resection offers a significant chance of long-term survival. In patients with benign mesothelioma, none had recurrence nor died of disease after adequate resection.

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.
