Although carcinoid tumors have occurred rarely in benign teratomas of the ovary and the testis, we believe this case is the first reported of carcinoid arising in a benign cystic teratoma of the kidney. The patient was admitted to the Tagawa Hospital with a left abdominal mass and severe epigastric pain. Retrograde and intravenous pyelograms revealed marked dilatation of the left kidney; a renal tumor was diagnosed clinically. At operation, a polycystic tumor weighing 1400g was removed. Histologically, a carcinoid tumor was evident among teratoid tissues, such as columnar epithelium, cartilage, smooth muscle, and mucous secretory glands. The patient did not have a carcinoid syndrome and had an uneventful recovery.
虽然类癌瘤在卵巢和睾丸的良性畸胎瘤中很少见，但我们认为该病例是首例报道的发生于肾良性囊性畸胎瘤中的类癌。患者因左腹部肿块和严重上腹部疼痛入住田川医院。逆行肾盂造影和静脉肾盂造影显示左肾明显扩张；临床诊断为肾肿瘤。手术中，切除了一个重1400克的多囊性肿瘤。组织学检查显示，在柱状上皮、软骨、平滑肌和粘液分泌腺等类胎组织中可见类癌瘤。患者无类癌综合征，恢复顺利。
