Hemoptysis due to a lung metastasis of renal cell carcinoma: A case report

[摘要] A 53-year-old man with a history of surgery for renal cancer was referred to our hospital due to massive hemoptysis. Contrast-enhanced CT revealed a well-enhanced pulmonary nodule suggestive of a tumor (diameter of 16 mm), which was considered a causal lesion. Bronchial artery embolization was successfully performed and subsequently hemoptysis disappeared. However, hemoptysis recurred 6 months later, and the tumor was surgically resected. Pathological examination revealed the resected tumor was a lung metastasis of renal cell carcinoma, which directly invaded into pulmonary bronchus. Hemoptysis secondary to lung metastasis of renal cell carcinoma has rarely been reported in the literature.
