title: Human papillomavirus type-16 positive endobronchial metastasis from uterine cervical cancer.
abstract: Although the lung is the most common site of metastasis from extrapulmonary malignancies, endobronchial metastases (EBM) are relatively rare. EBM typically originate from breast, colorectal, or kidney cancer. EBM from uterine cervical cancer is relatively rare and is difficult to confirm. In this study, we report a case of EBM in a patient with previously treated uterine cervical cancer. In this case, differentiation of the EBM from primary bronchogenic carcinoma with clinical, radiological, and pathologic findings was difficult. As identical human papillomavirus (HPV)-16 DNA was detected in both the EBM and in previously resected tissues from the prior uterine cervical cancer, the patient was diagnosed with EBM from uterine cervical cancer. HPV genotyping may aid in discriminating EBM from primary bronchogenic carcinoma in patients with uterine cervical cancer.
