Endobronchial metastasis from cancer of the breast.
Endobronchial metastasis is reported to occur in less than 5% of the autopsies of patients dying with extrathoracic malignant neoplasms. Frequently associated primary tumors include those of the kidney, pancreas, colon, ovary, and thyroid. To our knowledge, this is the first report of a case of cancer of the breast which metastasized to the mucosa of a major bronchus. The possible factors involved in the widespread, early unusual spread in this 25-year-old woman are discussed.
