Endobronchial Metastasis from Renal Cell Carcinoma as a Reason for Recurrent Pulmonary Infections

Endobronchial metastases (EBM) secondary to extrathoracic malignancies are very rare. Breast cancer, colorectal cancer and renal cell carcinoma represent the most common types of cancer leading to endobronchial metastases. They usually represent a late manifestation of other types of cancer and their prognosis is generally poor averaging a survival of 1–2 years in most case series. Due to their rarity, they remain a challenge for clinicians regarding whether they are primary lung tumors or not. This case report article intends to present a case of a young man with a left nephrectomy due to Clear-Cell Renal Cell Carcinoma, who developed EBM 7 years later and to summarize available data in the field. Furthermore, the utility of diathermic snare as a treatment approach for this entity is highlighted.
