In contrast to the healthy population, distal airway bacterial colonization may occur in patients with chronic lung diseases, who often have altered pulmonary defences. However, the information dealing with this issue is insufficient and is based mainly on nonspecific samples, such as sputum cultures. Using quantitative cultures of bronchoscopic protected specimen brush (PSB) and bronchoalveola...

This article is a survey of 476 consecutive cases of tumor death for heart involvement. The somewhat selected group of cases (from a Veterans Administration hospital) shows an incidence of cardiac metastasis of 19.1 per cent. The bulk of tumors metastasizing to the heart were bronchogenic carcinoma, malignant melanoma, malignant lymphoma, and carcinoma of the pancreas and esophagus. Electrocard...

A case of endobronchial granular cell tumor and an adenocarcinoma in the same lobe of the lung are presented. A review of the literature documents 2 cases where there was coexistence of a bronchogenic carcinoma and a granular cell tumor. The different theories regarding the origin of granular cell tumors are considered. The treatment of choice would be that indicated for the carcinoma irrespect...

The presentation of a Nocardia infection is quite variable. We report a case of nocardiosis presenting as endobronchial obstruction with postobstructive pneumonia and atelectasis, in a patient with a low index of suspicion for bronchogenic carcinoma. Our report emphasizes the importance of considering the diagnosis of endobronchial nocardiosis in patients with endobronchial obstruction and a lo...

57 Resection of solitary small-bowel metastases from bronchogenic carcinoma may be curative in the absence of residual or other metastatic disease. Although most cases of smallbowel metastases have occurred in patients with advanced disease, in whom small-bowel resection is followed by imminent demise, we report a case of isolated metachronous jejunal metastases from a squamous cell carcinoma t...
