A case of transitional cell carcinoma of the bladder in a juvenile patient

A case of transitional cell carcinoma of the bladder in a 18-year-old female is presented. Cystoscopic examination revealed a papillary tumor on the left lateral wall. Histopathology of the excised tumor showed transitional cell carcinoma, G1 > 2, pT1a. Recurrence has not been observed for about 1 year, after intravesical pirarubicin therapy.     

A case of transitional cell carcinoma of the bladder in a juvenile patient

A 15-year-old male was referred to our hospital with the chief complaint of gross hematuria. Cystoscopic examination revealed a papillary tumor on the posterior wall. Transurethral resection of the bladder tumor was performed. Histological examination of the excised tumor showed transitional cell carcinoma, grade 1, pTa. Recurrence has not been observed for about 2 years after the operation. We investigated 54 previously reported Japanese cases of bladder cancer before age twenty including the present case.     

Alpha-fetoprotein-producing transitional cell carcinoma of the urinary bladder: a case report

We report a 76-year-old man with alpha-fetoprotein (AFP)-producing transitional cell carcinoma of the bladder. Although the serum level of AFP was 1,428 ng/ml, and he was anti-hepatitis C virus (anti-HCV) antibody-positive, liver tumors were not detected by either a computed tomography (CT) scan or a hepatic angiography. However, removal of a bladder tumor by transurethral resection and subsequent pathological examination revealed a grade III transitional cell carcinoma (TCC). Furthermore, immunohistochemical detection of AFP was diffuse-positive. After the tumor partially responded to concomitant chemoradiotherapy, the serum AFP levels decreased to 966 ng/ml. However, the tumor eventually progressed with multiple lung metastases, and serum AFP levels increased to 3,906 ng/ml. In conclusion, AFP-producing TCC of urinary bladder is rare, and the nature and pathophysiology remains unclear and warrants further investigation.     

A case report: small cell carcinoma transformed from transitional cell carcinoma of the urinary bladder

A 72-year-old man presented with gross hematuria. Cystoscopy showed a non-papillary tumor at the right side of the posterior wall. Transurethral resection of the bladder tumor (TURBT) was performed. Pathologic findings demonstrated superficial transitional cell carcinoma (TCC). However, recurrent tumors were detected at the same location after 69 months' follow up. TURBT was done for the biopsy and pathologic examination showed muscle-invasive TCC. After two courses of neoadjuvant chemotherapy (MVAC), we performed radical cystectomy with Hautmann's continent reservoir. Pathologic findings revealed small cell carcinoma without any TCC features. Immunohistochemical staining using chromogranin A and synaptophysin was positive in the latest TURBT and the radical cystectomy specimens. We report a case of primary small cell carcinoma transformed from TCC of the urinary bladder.     

Leiomyosarcoma and transitional cell carcinoma in the urinary bladder: a case report

A 74-year-old man was admitted for asymptomatic macroscopic hematuria. He had undergone transurethral resection of bladder tumor (TURBT) due to transitional cell carcinoma 30 years ago. Pelvic CT showed two invasive bladder tumors. A 5 cm tumor was on the dome and a 1 cm tumor was on the left lateral wall. TURBT was performed. Pathological examination revealed that they were leiomyosarcoma and transitional cell carcinoma. Radical cystectomy plus bilateral cutaneousureterostomy was performed. He died of lung metastases and local recurrence after 6 months.     

A case of vaginal implantation of transitional cell carcinoma of the bladder]

An 82-year-old female presented with asymptomatic gross hematuria in June 1997. Urethrocystoscopy revealed a multiple papillary tumor of the bladder and posterior urethra. Histology of the punch biopsy specimens of the tumor revealed transitional cell carcinoma (TCC), grade 2 (G2). CT scan showed no distant metastasis and extravesical invasion. The patient was treated by intravesical instillation of adriamycin (ADM), drip infusion of low dose cisplatin (CDDP) and irradiation of the bladder. As the treatment caused a significant tumor shrinkage, transurethral resection of the tumor was performed. Histologically, the tumor revealed no invasion to the muscular layer of the bladder. In April 1998 she noticed genital bleeding, and a multiple papillary tumor was found on the vaginal wall. Histology of punch biopsy specimens of the vaginal tumor showed non-invasive TCC, G2. MRI and specimens of all layer needle biopsy showed no infiltration outside the bladder wall and the vaginal wall. Irradiation of the cavity of the vagina and uterus was made under the diagnosis of superficial vaginal TCC. We assume that vaginal implantation via irrigating fluid or urine has occurred.     

A case of transitional cell carcinoma of the bladder with heterotopic bone formation

A 85-year-old woman consulted our clinic due to asymptomatic macrohematuria on January 6, 1987. In the cystoscopic examination, solitary and pedunculated bladder tumor was revealed. This tumor was located on the retrotrigonal region near the right ureteral orifice. On January 20, transurethral resection of bladder tumor was planned but the base of the tumor was stony hard, so complete resection was not performed. On February 10, transurethral resection of bladder was performed repeatedly. At that time, the cystoscopic finding showed that the tumor size had increased and transurethral bladder ultrasonography showed invasion into the deep muscular layer. On February 17, total cystectomy and ileal conduit was done. Histological examination revealed poorly differentiated TCC with osteoid, bone and cartilage. This patient was discharged in good condition on March 27. Heterotopic bone formation in the bladder tumor is rare. Ten cases were collected from the literature. We report a case of heterotopic bone formation and discuss the mechanism of the etiology.     

A case of double cancer: renal cell carcinoma and transitional cell carcinoma of urinary bladder

This is a case report on a patient with double cancer of kidney and urinary bladder. The patient was a 65-year-old female, and she was admitted with the chief complaint of gross hematuria and right flank pain. After careful examinations, she was diagnosed with right nonfunctioning kidney caused by invasive bladder cancer. Computerized tomography incidentally revealed a mass in the upper pole of the left kidney. Selective left renal arteriography showed stretched arteries and irregularity and tortuosity of the smaller vessels. She was diagnosed with double cancer of bladder and left kidney. Owing to the damage of the right renal function, left partial nephrectomy, total cystectomy, right nephroureterectomy and left ureterocutaneostomy were performed. According to DMSA scintigraphy measured 15 days later, the uptake value of the left kidney was 13.25%, compared to the preoperative value of 25.62%. To date, this case is 36th reported case in Japan.     

A case of transitional cell carcinoma of the bladder with active urinary tract tuberculosis

A 63-year-old man was admitted to our hospital complaining of painful urination. Urinalysis demonstrated pyuria and microscopic hematuria. Cystoscopy revealed the bladder tumor and the reddish mucosa. Transurethral biopsy was performed and the pathological examination showed transitional cell carcinoma in the bladder tumor and epithelioid granuloma in the reddish mucosa. Acid-fast bacilli smeas of urine sample and urine culture of Mycobacterium tuberculosis were positive. Therefore the treatment of urinary tuberculosis was started and the patient received intra-arterial chemotherapy combined with radiation. After the therapy, radical cystectomy and bilateral cutaneous ureterostomies were performed. Pathological study revealed transitional cell carcinoma and epithelioid granuloma in the removed bladder. The reports of urinary epithelial carcinoma with urinary tract tuberculosis were rare and, including our case, the 10 cases in Japanese literature are reviewed.     

A case of bladder transitional cell carcinoma with sigmoidovesical fistula due to diverticulitis

We present a case of bladder transitional cell carcinoma with sigmoidovesical fistula due to diverticulitis. The patient was a 65-year-old male who had been suffering from recurrent abdominal pain with high fever for the past 6 months. He noticed pneumaturia and cloudy urine several times. He visited a doctor complaining of macroscopic hematuria and high fever, and was treated under the diagnosis of acute prostatitis. In our University Hospital cystoscopy showed a papillary bladder tumor. Pathological study of the tumor revealed transitional cell carcinoma, grade II, noninvasive type. Multiple diverticulosis of sigmoid colon was identified with barium enema examination. We performed transurethral resection of the bladder tumor. Three weeks later, the sigmoidovesical fistula was treated by primary resection of the sigmoid colon and wedge resection of the bladder including fistula.     

A case of transitional cell carcinoma in a pyelocaliceal diverticulum

A 63-year-old man visited our hospital because of painless macrohematuria. Drip infusion pyelography and retrograde pyelography revealed a space-occupying lesion with extravasation of contrast medium to upper caliceal system. A computed tomographic study revealed an intrarenal solid moiety and further more, arteriography showed the arterial encasement and fine neovascularity of the lesion. On gross section of the extirpated kidney, a cystic cavity measuring 3 by 3 cm existed at the upper pole and apparently channeled to the upper caliceal system. Small stones were found in the cystic cavity. Histopathologically, the wall of the cavity was covered with layered squamous cells and a part of the wall developed metaplasic transitional cell carcinoma proliferation which invaded into the renal parenchyma and renal pelvis, as well.     

Surgical management of bladder transitional cell carcinoma in a vesicular diverticulum: case report

We report a case of primary transitional cell carcinoma (TCC) of a bladder diverticum along with a literature review. A 55-year-old male presented with painless gross hematuria. A histological diagnosis of TCC within a bladder diverticulum was made following cystoscopical examination. Initially transurethral resection of bladder tumour with subsequent intravesical chemotherapy followed. As a result of recurrence and in view of bladder-sparing therapy, a distal partial cystectomy was performed. This report demonstrates that conservative bladder-sparing treatment can be achieved and subsequently followed by vigilant cystoscopy.     

Clinical study of transitional cell carcinoma of the prostate associated with bladder transitional cell carcinoma

BACKGROUND: Transitional cell carcinoma of the prostate in patients with bladder cancer appears to influence the prognosis and affects the decision about therapeutic modality. Therefore, it is important to characterize transitional cell carcinoma associated with bladder cancer. METHODS: From April 1980 to December 1998, 81 male patients underwent total cystoprostatectomies for transitional cell carcinoma of the bladder. The 81 cystoprostatectomy specimens were examined to clarify the characteristics of prostatic involvement by transitional cell carcinoma. The extent, origin, mode of spread and risk factor of prostatic involvement as well as the prognosis were investigated. In 13 of 15 patients with prostatic involvement the prostate was examined by sequential step sections. RESULTS: Prostatic involvement was observed in 15 of 81 patients (18.5%). Prostatic urethral involvement, invasion to prostatic duct/acinus, prostatic stromal invasion and extraprostatic extension and/or seminal vesicle involvement were recognized in 12 (80%), 14 (93.3%), six (40%), and five (33.3%) of the 15 patients, respectively. Twelve of the 15 patients (80%) with prostatic involvement had papillary or non-papillary tumors (i.e. carcinoma in situ) both in the prostatic urethra and prostatic duct. In 10 of these 12 patients (88.3%), there was contiguity between prostatic urethral and ductal tumors. Seven of the 23 patients (30.4%) with carcinoma in situ of the bladder showed prostatic involvement, which increased to 50% in the presence of carcinoma in situ of the trigone or bladder neck. CONCLUSIONS: Eighty per cent of the patients with prostatic involvement showed papillary or non-papillary tumors both in the prostatic urethra and prostatic duct. There was a high level of contiguity between both tumors. Patients with carcinoma in situ of the trigone or bladder neck revealed significantly higher incidence of prostatic involvement.     

膀胱移行细胞癌微血管分型及意义

为探讨膀胱移行细胞癌组织中肿瘤微血管不同类型与浸润和转移的关系，应用免疫组织化学ＳＰ法在６１例膀胱移行细胞癌组织中对第Ⅷ因子相关抗原进行表达并计数，根据肿瘤组织中微血管（ＭＶ）的分布特点及其与肿瘤组织的关系，将ＭＶ分为两型：Ⅰ型为肿瘤组织内ＭＶ，位于癌组织内，血管迂曲，扩张，变形；Ⅱ型为肿瘤旁ＭＶ，位于肿瘤边缘，血管分布不均。结果显示浸润性癌组的Ⅱ型ＭＶ数显著高于Ⅰ型ＭＶ数（Ｐ＜００５），在浅表性癌组中Ⅰ，Ⅱ型ＭＶ数之间无显著性差异（Ｐ＞００５），伴淋巴结转移的癌组织Ⅱ型ＭＶ数显著高于Ⅰ型ＭＶ数（Ｐ＜００５）。认为肿瘤血管的生长有很大的异质性，肿瘤边缘的微血管与肿瘤的浸润有密切关系。     

Recurrent transitional cell carcinoma of the bladder in a young woman: report of a case]

A rare case of transitional cell carcinoma of the bladder in an 18-year-old female is presented. The chief complaint was gross hematuria and pain on urination. Transurethral resection was performed and pathological findings were low grade transitional cell carcinoma without invasion. During a 5-year follow up, she had relapse of the bladder tumor twice. Transitional cell carcinoma of the bladder in children and adolescents may be low grade, low stage and rarely recurrent, but the possibility of recurrence does exist. We emphasize the necessity of periodic cystoscopy for following up young adolescents with transitional cell carcinoma of the bladder.
