Metachronous endobronchial metastasis from uterine cervical adenocarcinoma

Malignant involvement of the lung can be primary or metastatic. Although primary lung cancer may be endobronchial, parenchymal or both, metastases to the lung are generally parenchymal. However, less commonly, they may be endobronchial. The lungs are the most common site of metastases among all the malignancies. Common extrapulmonary malignancies causing endobronchial metastases (EBMs) are breast, colorectal and kidney. EBMs from uterine cervical cancer are very rare. Although there are a few case reports in the medical literature describing EBM from cervical cancer, none are from adenocarcinoma histology. In this study, we report a case of EBM which on histopathological examination and immunohistochemistry were found to be from a prior adenocarcinoma cervix. Differentiating EBM from bronchogenic carcinoma and other more common extrapulmonary solid organ malignancies may present a clinico-pathological and radiological challenge.
