胆嚢転移を伴った腎細胞癌

RENAL CELL CARCINOMA WITH GALLBLADDER METASTASIS

　3年前より腎腫瘤を指摘されていた69歳の男性が当科を受診した。画像診断で右腎腫瘤，対側副腎腫瘤，胆嚢内ポリープ状腫瘤が認められた。右腎，左副腎，胆嚢摘除術が施行され，病理学的に右腎細胞癌（淡明細胞型）の胆嚢および副腎転移と診断された。

A 69-year-old man presented with a right renal mass which had been detected for 3 years. The diagnostic imagings disclosed a right renal mass, a mass in the contralateral adrenal gland and a polypoid mass in the gallbladder. He underwent right nephrectomy, left adrenalectomy and cholecystectomy. The surgical specimens of the gallbladder and adrenal gland showed histological evidence of clear cell carcinoma with the same characteristics as those of the primary renal tumor.
