Solitary Pulmonary Nodules in Patients with Extrapulmonary Neoplasms

摘要: PURPOSE: To determine the frequency of single lung metastasis, primary cancer, and benign lesions in patients with a solitary nodule extrapulmonary neoplasm. MATERIALS AND METHODS: The authors evaluated electronic charts 149 an malignant neoplasm pulmonary nodule. histologic characteristics were correlated those patient age smoking history. RESULTS: Patients carcinomas head neck, bladder, breast, cervix, bile ducts, esophagus, ovary, prostate, or stomach more likely to have bronchogenic carcinoma than metastasis (ratio, 25:3 for neck cancers; 26:8 other types cancer combined). salivary glands, adrenal gland, colon, parotid kidney, thyroid thymus, uterus had fairly even odds 13:16). melanoma, sarcoma, testicular carci...
