異所性尿管瘤に伴い憩室様拡張を示した女児wide urethra の1例

先天的女子尿道憩室あるいは, 拡張尿道は極めて稀である.これまでに, 尿管瘤に伴って, 憩室様の変化を示した症例は数例報告されているが, その大多数が, 尿道内に開口する拡張した尿管を誤って憩室と判定したものであり, 他は, 尿管瘤のpoor backingのためのcvcrsionや, Gartner's cystとの交通によるものである.今回われわれは, 3カ月の女児で, 特に右側尿道の著明な拡張を示し, この憩室様の拡張が尿管瘤内に翻転を示す症例を経験したので報告した, 本症例は内視鏡的にも手術時の所見からも, 尿管瘤は膀胱頸部以下には認められず, 発生学上右側後部尿道の形成不全が関与したものと考えられた.A rare case of wide urethra in a female infant mimicking as a urethral diverticulum in association with ectopic ureterocele is reported. The ureterocele terminated just below the bladder neck, but the diverticulum-like structure everted from the wide urethra, protruding towards the ureterocele. Weakness of the urethral wall, distal to the actual ureterocele may produce such an abnormal radiologic finding. The pertinent literature is reviewed

悪性度の高い組織像を示したポリープ様尿管腫瘍の1例

A case of a lobulated polypoid tumor of the ureter showing histologically high grade malignancy is reported. Such a tumor is rare in the bladder, and to date none have been documented in the ureter. This tumor is probably the most malignant urothelial tumor of the inverted type in the urinary tract, including inverted papilloma

大きな腫瘤を形成した腺性膀胱炎の１例 : 臨床的・組織学的・粘液組織化学的検討

A case of large protruding cystitis glandularis is reported. A 36-year-old man was admitted to our hospital due to acute cholecystitis, and large protruding masses were incidentally found in the urinary bladder by abdominal ultrasonography. The histological study revealed that they consisted of a large number of Brunn's nests with or without cysts which were often accompanied with columnar epithelial metaplasia, and of glandular structures closely resembling the colonic crypts. The mucin-histochemical study demonstrated glandular lesions in the bladder secreted colonic type mucin, and endocrine cells positive with Grimelius' staining. A review of literature disclosed 19 clinical cases of cystitis glandularis, since 1970, in Japan, but such a large protruding lesion as this case is rare. We first performed detailed histological and mucin-histochemical studies for this clinical case
