Endobronchial localization - arena of two tumors: a case report

The lung is a common arena for metastases of tumors with different localization, but endobronchial localization of metastases is very rare. The most common tumors with endobronchial localization of metastasis are renal, breast, and colorectal cancer. We report a man presenting with cough and hemoptysis. Endobronchial biopsy showed renal cell carcinoma and micro-invasive bronchogenic squamous cell carcinoma. Endobronchial metastases from renal cell carcinoma are rare. The squamous cell lung cancer is one of the most common cancers in men, but the combination of renal cell carcinoma and micro-invasive squamous cell carcinoma with endobronchial localization is a casuistic case
