CEA・CA19-9・SCC産生腎盂腫瘍

Renal pelvic tumor producing CEA,CA19-9 and SCC:A case report

　症例は81歳，女性。発熱を主訴に内科を受診したが改善せず，腎盂腎炎の疑いで当科に紹介された。血清CEA，CA19-9，SCC抗原の上昇を認めた。消化管を精査するも，異常を認めなかった。逆行性腎盂造影で左腎盂腫瘍を認めたため，左腎尿管全摘除術が施行された。病理組織学的には腎盂移行上皮癌を示し，免疫組織学的検索では，腫瘍組織がCEA，CA19-9，SCCに陽性を呈した。術後腫瘍マーカーは正常化した。

　An 81-year-old woman with high fever was referred to our department because of suspected pyelonephritis. Serum CEA,CA19-9 and SCC antigen were elevated. Left retrograde pylography revealed irregular filling defects involving calices and renal pelvis. Under the diagnosis of renal pelvic tumor,left total nephroureterectomy was performed. Pathological diagnosis of the surgical specimen was transitional cell carcinoma,grade 2＞3,pT3 with positive immunostaining for CEA,CA19-9 and SCC. Serum CEA,CA19-9 and SCC antigen returned to normal after the operation.
