Endobronchial Metastasis of Uterine Cervix Cancer: A Two Case Reports and a Review of the Literature

ABSTRACT

Endobronchial metastasis from uterine cervix cancer defines a bronchoscopically visible nonpulmonary neoplasm metastatic to the bronchus and histologically identical to cervix cancer. Endobronchial metastasis of uterine cervix cancer is rare, therefore, it is difficult to diagnose without pulmonary symptoms or abnormal radiological findings. Moreover, endobronchial metastasis of a nonpulmonary neoplasm is difficult to differentiate from a primary pulmonary neoplasm. The incidence of endobronchial metastasis is increasing because of the regular use of fiberoptic bronchoscopy and the longer survival of cancer patients. This study describes our experience of two patients with pulmonary symptoms and abnormal radiologic findings during the follow up of uterine cervix cancer, who were diagnosed as having endobronchial metastasis from uterine cervix cancer, and includes a brief review of related articles.
