Unusual endotracheal and breast metastasis from renal clear cell carcinoma: a case report

We report a case of a woman affected by a metastatic renal clear cell carcinoma who showed unusual metastasis into the trachea and in the right breast 17 years and 21 years after nephrectomy respectively. Two endotracheal metastasis were identified during rigid bronchoscophy and were treated with endotracheal electro-surgery. Solitary metastasis in the right breast was identified by a mammography that revealed a dense mass of 1.5 cm at lower outer quadrant and she underwent to a right breast quadrantectomy. Histological examination showed a clear cell renal carcinoma metastasis as for the trachea as for the breast mass.
