Two cases of papillary carcinoma of the bladder are presented in which the ureter could not be demonstrated by standard radiographic techniques. Computed tomography (CT) allowed identification of the tumor filled ureter. Intraureteral papillary tumor has a radiographic density (CT number) above that of water but less than that of the enveloping ureter.

Forty patients with carcinoma in situ of the bladder were reviewed. They included 15 patients with primary carcinoma in situ, 8 with secondary carcinoma in situ and 17 with concurrent carcinoma in situ. Twenty-one (66%) of 32 patients with primary or concurrent carcinoma in situ complained of urinary frequency and pain on urination, whereas no patients with secondary carcinoma in situ complained of such symptoms. Nearly all patients with concurrent or secondary carcinoma in situ had gross hematuria, whereas only 7 (47%) of 15 patients with primary carcinoma in situ had gross hematuria. Two patients without any symptoms were diagnosed by incidental positive urinary cytology. Concurrent carcinoma in situ was always associated with multiple papillary tumor. Dominant grade of the papillary tumor was classified as grade 3 in 11 patients and as grade 2 in 6. The simultaneous presence of carcinoma in situ of the urethra was found in 13 (46%) patients and those of the ureter in 17 (74%). Fourteen patients (35%) with carcinoma in situ developed an invasive carcinoma. Of these, 4 (10%) died of cancer. Bacillus calmette-guerin instillation was effective in 13 of 15 patients (87%). These results indicate that carcinoma in situ of the bladder may develop an invasive cancer, may remain in the epithelia, or may be associated with multiple superficial tumor. It should be emphasized that patients with multiple superficial bladder tumor may be associated with carcinoma in situ even if the superficial tumors are of low grade and urine cytology is negative.

The patient was a 61-year-old male who had undergone right nephrectomy for nephrolithiasis 35 years before. He had been on hemodialysis for 6 years for chronic renal failure caused by left renal staghorn calculus and hydronephrosis. He was admitted to our hospital because of macroscopic hematuria and sense of residual urine which had persisted for 3 months. Cystoscopic examination showed an extensive papillary tumor in the urinary bladder, which histologically was an adenocarcinoma. Giant left hydronephrosis associated with staghorn calculus noted by KUB and CT scan. Total cystectomy, intraoperative radiotherapy, and left nephrostomy were performed under the diagnosis of adenocarcinoma of the urinary bladder and left hydronephrosis. The bladder tumor was found to be a mucinous adenocarcinoma. The patient died from a cerebral hemorrhage on the 17th postoperative day. At autopsy, tumors were found in the pelvis of the left kidney and the middle and lower regions of the ureter, which were adenocarcinoma like the bladder tumor. Adenocarcinoma occurring simultaneously in the renal pelvis and bladder has not been previously reported to our knowledge, in Japan or elsewhere.

Ten pyeloureteral systems in 8 patients (mean age 74 years) with cytologically proved ureteral carcinoma in situ (1 combined with ureteral papillary tumors) were perfused with bacillus Calmette-Guerin via a percutaneous nephrostomy tube. In 4 patients cytology results remained negative after 1 treatment course during an observation time of 18 to 28 months. In 1 patient a papillary tumor persisted while cytology results became negative for carcinoma in situ. Two patients with bilateral disease had repeated perfusion of bacillus Calmette-Guerin until cytology results became negative and they remained negative during observation for 18 months in 1. The other patient had a multifocal recurrence of carcinoma in situ, combined with a stage T1, grade 3 urothelial cancer in the bladder after 12 months and a recurrence of carcinoma in situ in 1 ureter after 24 months. In 1 patient treatment was stopped prematurely after severe septicemia. Although our short-term results are promising, percutaneous perfusion of bacillus Calmette-Guerin for carcinoma in situ of the upper urinary tract should be considered as an investigational treatment modality until long-term results are available.

A 62-year-old male was admitted to our clinic with the complaints of gross-hematuria and miction pain. Cystoscopic examination revealed non-papillary tumor around the orifice of the left ureter and the left wall. Histopathological findings of the biopsy specimen demonstrated signet-ring cell carcinoma, and the specimen was stained positively by the peroxidase-antiperoxidase technique. No malignant findings in any other organs including gastrointestinal tract and prostate were detected. This patient underwent total cystectomy with ileal conduit and histopathological staging was pT3bNOMO. He was followed with no evidence of local recurrence or metastasis for 29 months after operation. The 45 reported cases with primary signet-ring cell carcinoma of the urinary bladder including our case are reviewed and some characteristics of this entry are discussed.

A 63-year-old man complained of hunger epigastralgia. X-ray and endoscopic examination demonstrated Borrmann II type gastric carcinoma. Radical gastrectomy was performed on October 20, 1982. The histological findings revealed moderately differentiated tubular adenocarcinoma. In May 1983, right hydronephrosis was recognized by ultrasonography. A papillary tumor was visualized in the right ureter in retrograde pyelography, and percutaneous transrenal urinary tract drainage was performed. Cytological findings revealed class V. Total nephro-uretectomy was performed on June 16, 1983. The histological findings revealed transitional cell carcinoma.

Two cases of carcinoma in a diverticulum of the bladder were experienced. The first case was of a 50-year-old male who presented in February, 1981, complaining of asymptomatic microhematuria. The excretory urogram revealed a diverticulum in the left lateral aspect of the bladder which was causing shift of the lower ureter to the median side. The cytology report of voided urine was class III. Diverticulectomy was performed and pathologic findings was a transitional cell carcinoma, grade 1, stage 0. The patient has been free of recurrence for the past 54 months. The second case was of a 67-year-old male with the chief complaint of pollakiuria. Non-papillary tumor in a diverticulum of the bladder was found by cystoscopy and computed tomography. Tumor biopsy and urinary diversion by ileal conduit were performed in the usual manner. The pathologic finding was transitional cell carcinoma of grade 11 malignancy. The patient died of intestinal obstruction on January, 19, 1984, about 15 months after the surgery. The 117 cases of carcinoma in a diverticulum of the bladder we found in the Japanese literature are reviewed briefly.

A case of multicentric papillary adenocarcinoma arising in the renal pelvis and proximal ureteral mucosa of a 35-year-old man is presented. The left nephrectomy specimen demonstrated multiple, fungating, papillary tumors. The largest tumor measured 10 X 9 X 6 cm and invaded the renal parenchyma. Smaller tumors with long stalks were found. Microscopically, the papillary fronds of each neoplasm were lined by a single layer of cuboidal to low columnar epithelium admixed with a few areas of invasive tubular adenocarcinoma. The adjacent pelvic mucosa was the site of cuboidal epithelial metaplasia. The ultrastructure of both the papillary tumor and the pelvic mucosa suggested that they originated from the nonmucigenic metaplastic epithelium with a partial similarity to the lining of the proximal convoluted tubule. The growth pattern and the multicentric development of this unusual neoplasm suggest that this is a case of the malignant counterpart of the nephrogenic adenoma in the kidney and ureter, and reflect a biologic behavior corresponding to ordinary urothelial papillary tumors.

Inverted papilloma of the ureter is a rare tumor generally considered to be a benign lesion. We present a case of ureteral inverted papilloma with malignant transformation and review the literature. Ten cases of ureteral inverted papillary tumors in Japan and 13 cases of inverted papillary tumors associated with malignancy in the urinary tract in the world literature have been analyzed to define their features. Inverted papillary tumors of the ureter have distinct clinicopathological features, but most are discovered retrospectively after nephroureterectomy. From the standpoint of clinicopathological features, inverted papillary tumor of the ureter should be distinguished from its exophytic counterpart with respect to the treatment. If the tumor can be diagnosed macro- and microscopically during surgery as inverted papilloma or malignant inverted papillary tumor without invasion, partial ureterectomy including the lesion may be recommended. Furthermore, we propose the hypothesis that inverted papillary tumor could be a neoplasm of basal cell origin in the transitional epithelium, termed 'basal cell urothelioma'.

A 63-year-old male with transitional cell carcinoma of the bladder underwent total cystectomy. Five years later sequential excretory urography and urinary cytologic examination revealed tumor recurrence in the left pelvis and ureter; left nephroureterectomy was performed in July, 1984. In December, 1985, he complained of macrohematuria and urinary cytology was positive. Ileal conduitgraphy showed filling defects at the bilateral uretero-ileal anastomosis, where two papillary lesions were disclosed by endoscopic examination. In January, 1986, total extirpation of the ileal conduit and reconstruction of a new ileal conduit was performed. Macroscopically the two lesions were found to be a papillary tumor at left uretero-ileal anastomosis and a polypoid tumor distal to right uretero-ileal anastomosis. Histological examination revealed both tumors to be grade II transitional cell carcinoma. This rare case is discussed and the literature is reviewed.
