Synchronous triple urogenital cancer (renal cancer,bladder cancer,prostatic cancer): a case report

A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer.     

A case of renal cell carcinoma and bladder carcinoma associated with von Hippel-Lindau disease

A case of renal cell carcinoma and bladder carcinoma associated with von Hippel-Lindau disease is reported. A 31-year-old female was referred to the Department of Urology for further examination of right renal mass which was incidentally found on abdominal computed tomography (CT). The patient was operated on spinal hemangioma in May 19 and July 8, 1975, on cerebellar hemangioblastoma in July, 1976 and June 10, 1981 and on cerebellar cyst in June 20, 1988. Angiography revealed three hypervascular renal tumors in the right kidney. Cystoscopy revealed a papillary bladder tumor (TCC Grade 1). Transurethral resection of bladder carcinoma was performed on July 28, 1988. Right radical nephrectomy and lymphadenectomy were performed on August 2, 1988. Histopathologically, the tumor was renal cell carcinoma of clear cell type (Grade 1). Postoperative course was uneventful and the residual kidney is being followed up in the outpatient clinic.

Abstract：

Objective To investigate the incidence of urological malignancy in renal allograft recipients and explore the mechanism of increased incidence in China and the management. Methods A retrospective study was performed on 22 patients with urological malignancy in renal allograft recipients between 1978 and 2010. Results Twenty-two cases of urological malignancy were diagnosed by pathologic evidence, including 9 cases of transitional cell carcinoma (TCC) of bladder, 1 case of squamous cell carcinoma of bladder, 1 case of adenocarcinoma of bladder, 1 case of TCC of pelvis, 1 case of TCC of bladder and pelvis, 1 case of TCC of ureter complicated with adenocarcinoma of bladder, 2 cases of TCC of ureter, 2 cases of TCC of ureter and bladder, 3 cases of clear cell carcinoma of kidney, and 1 case of undifferentiated carcinoma of kidney. All the malignancies belonged to native organs. All the patients suffering bladder cancer had normal function of allograft. Five patients with TCC of pelvis or ureter survived and 2 cases died early after operation. All the patients suffering renal carcinoma deceased within 6 months after diagnosis. One-year survival rate was 73. 7 % after the diagnosis of urological malignancy. Conclusion Urological malignancy ranked highest in malignancy in renal allograft recipients, and rare pathological types of urological malignancy in non-renal allograft recipients are often demonstrated. The strategy of treatment should take consideration of the relationship between the usage of immunosupressive agents and the preservation of allograft function. It is critical for the therapy of malignancies to possess satisfactory allograft function. The prognosis of renal cell carcinoma is poor.     

A renal cell carcinoma metastasis to the contralateral perirenal fat : a case report

A 53-year-old woman was admitted with right lower abdominal pain in November 1993. Computed tomography (CT) revealed a right renal tumor, suspected to be a renal cancer. She underwent right radical nephrectomy in December 1993. The pathological diagnosis was clear cell carcinoma, pT2, grade 2. In May 2006, follow-up CT showed a tumor arising from the left perirenal fat. Laparoscopic tumor excision was performed in August 2006. The pathological diagnosis was metastatic clear cell carcinoma.     

Clear cell adenocarcinoma arising from abdominal wall endometriosis mimicking urachal tumor

A 41-year-old woman presented with severe lower abdominal pain. She had a history of 2 cesarean deliveries. Magnetic resonance imaging (MRI) revealed a 4.3 × 4.6 × 4.8-cm mass on the urinary bladder dome. Preoperative diagnosis was invasive urachal tumor. Wide resection of the tumor was performed. The histopathological diagnosis was clear cell adenocarcinoma with endometriosis. MRI revealed normal-sized ovaries and uterus. The definite diagnosis of clear cell carcinoma arising from abdominal wall endometriosis was made. Adjuvant chemotherapy with paclitaxel and carboplatin (total 6 courses) was planned. The patient has thus far received 4 courses of this treatment.     

Clear cell adenocarcinoma of the urinary bladder within a diverticulum

A rare case of clear cell adenocarcinoma within a bladder diverticulum is presented. A 69-year-old man presented to our institution with gross hematuria. Workup, including computed tomography and cystoscopy, revealed a papillary bladder mass within a bladder diverticulum near the right ureteral orifice. Biopsy of the tumor was performed, and the pathologic examination revealed clear cell adenocarcinoma. He underwent bladder diverticulectomy and remained disease free at 1 year of follow-up. The clinicopathologic characteristics of this entity compared with its most difficult pathologic differential diagnosis, nephrogenic adenoma, are reviewed.     

Solitary metastasis to the urinary bladder from renal cell carcinoma: a case report

A 48-year-old woman was referred to our hospital with a bladder mass which was detected by a general practitioner. Ultrasonography showed a small bladder tumor and right renal mass. Cystoscopy revealed a solitary, non papillary tumor at the right side of the retro-trigone. Computed tomography revealed a large tumor at the right kidney. Transurethral resection of the bladder tumor was performed. The histopathological diagnosis was clear cell carcinoma. There was no other distant metastasis. Sequentially, radical nephrectomy was performed. Histopathologically, the right renal tumor showed clear cell carcinoma. This was considered to be a case of a solitary metastatic bladder tumor from renal cell carcinoma.     

Synchronous neoplasms of the colon and kidney: analysis of 2 case reports

Up until only a few decades ago synchronous renal cell carcinoma associated with primary tumors of other organs was diagnosed almost exclusively in necropsy series. Recently the widespread use of ultrasonography and CT has permitted diagnosis of clinically silent renal cell carcinoma in patients undergoing a work-up for other primary tumors. We report two cases of synchronous colon and renal cancer: 1) a 75 year old woman presented bilateral pulmonary nodules at chest X-Ray and stratigraphy. Total-body CT scan showed multiple, apparently metastatic, bilateral pulmonary lesions and two tumors in the right kidney and ascending colon. A right nephrectomy and right hemicolectomy were performed. She succumbed after 18 months as a result of metastatic spread to the liver, lungs and bone; 2) a 64 year old man was discovered to have a colon cancer during a barium enema examination and endoscopy. CT scan of the abdomen yielded an incidental diagnosis of a tumor in the left kidney. A left nephrectomy and left hemicolectomy were performed. After 6 months CT revealed no evidence of recurrence or metastases. Histology findings revealed two primary malignancies in both cases: a clear cell renal carcinoma and an adenocarcinoma of the colon.     

Bladder metastasis of renal cell carcinoma : report of a case

A 65-year-old man presented with gross hematuria in 2004. Computed tomography (CT) showed a left renal mass, and he underwent laparoscopic radical nephrectomy. Pathological diagnosis was clear cell carcinoma (pT2N0M0, G2＞G3). Four years later, a right adrenal tumor was disclosed by follow-up CT. Then laparoscopic adrenectomy was performed. Histology showed metastasis of the renal clear cell carcinoma. In 2009, he noticed gross hematuria, and cystoscopy revealed a 2cm solitary, non-papillary tumor at the anterior wall of the bladder. At the same time, small solitary liver metastasis (6 mm) was observed on abdominal CT. Transurethral resection of the bladder tumor and resection of liver tumor was performed, and pathological diagnosis was clear cell carcinoma both in vesical and hepatic masses. Nine months after the last surgery, he is living with no obvious tumor recurrence. To our knowledge this case is the 34th case of bladder metastasis from renal cell carcinoma in the Japanese literature. We reviewed literature and discuss the clinical features of bladder metastasis of renal cell carcinoma.

Late relapse and urothelial carcinoma of residual ureter 16 years after radical nephrectomy: a case report

A 66-year-old male was referred to our hospital for evaluation of tumors in his left residual ureter and the lung. He had a history of left nephrectomy due to "malignant renal tumor", performed by a general surgeon at another hospital 16 years ago. Since a definitive diagnosis of the kidney was uncertain, we speculated that the original renal disease was a renal pelvic cancer and had metastasized in the residual ureter and the lung. We performed systemic chemotherapy followed by resection of residual ureter with bladder cuff Pathological examination revealed urothelial carcinoma. However, the lung tumors did not respond to salvage chemotherapy and slowly progressed. Bronchoscopic biopsy was performed 2 years later and histological finding showed clear cell type renal cell carcinoma.     

Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the urinary bladder associated with left renal pelvic carcinoma: a case report

We report a case of primary mucosa-associated lympoid tissue (MALT) lymphoma of the urinary bladder associated with left renal pelvic carcinoma. A 84-year-old woman showed microscopic hematuria during follow up for hypertention. Left renal pelvic tumor was found and she was referred to our hospital for further evaluation and managemant. She showed pyuria and Escherichia coli was detected by urine culture. Intravenous pyelography and computed tomography revealed the left renal pelvic tumor and solid bladder tumor. Transurethral resection of bladder tumor and left total nephroureterectomy were performed. Histologically, the left renal pelvic tumor was urothelial carcinoma > > adenocarcinoma, G2, pT2 and the bladder tumor was MALT lymphoma. Ga-scintigraphy showed no hot uptake suspicious of metastatic lesion. Then, external beam radiotherapy (36 Gy) was performed to the urinary bladder. She has been alive for 14 months with neither renal pelvic tumor nor MALT lymphoma showing any evidence of disease progression.     

A case of synchronous ipsilateral renal cell carcinoma and transitional cell carcinoma]

A case of synchronous ipsilateral renal cell carcinoma with renal pelvic and ureteral transitional cell carcinoma is reported. A 80-year-old man, who had had transurethral resection of bladder tumor three times, was admitted on August, 1989 for recurrence of bladder tumor. Excretory pyelography revealed a filling defect of left renal pelvis. Findings of retrograde pyelography and computed tomography were in accord with those of the excretory urograms. Under a diagnosis of the left renal pelvic and ureteral tumor associated with the bladder tumor, left nephroureterectomy with bladder cuff resection was performed. Pathological diagnosis was renal pelvic and ureteral transitional cell carcinoma with renal cell carcinoma, which existed incidentally in the same kidney. Double unrelated primary carcinoma in urinary tract, especially, double dissimilar primary carcinoma in the same kidney, is rare. To our knowledge, this case is the 20th double cancer in upper urinary tract reported in Japan.     

Renal-type clear cell carcinoma occurring in the prostate

Clear cell lesions of the urinary tract often present diagnostic challenges. We report a previously undescribed lesion in the prostate, occurring in a 73-year-old man who presented with hematuria and subsequently underwent transurethral resection of the prostate. A total of 24 g of tissue was removed, and in 4 of 17 blocks submitted a lesion morphologically and immunohistochemically similar to clear cell carcinoma of the kidney was noted. A thorough cystoscopic and full-body, radiologic workup was performed, but no renal tumor was discovered. Random cystoscopic biopsies of the bladder and prostatic urethra as well as bladder washings were benign. Subsequent needle biopsies of the prostate were also benign. The patient underwent a pelvic lymph node dissection with radical cystoprostatectomy and orthotopic Studer pouch diversion. There was organ-confined, ordinary-type prostatic adenocarcinoma (Gleason's 3 + 3) present bilaterally in the peripheral zone; no residual clear cell carcinoma was identified. All lymph nodes were negative, and the urinary bladder showed no dysplasia or neoplasia. We think this tumor represents a primary renal type of clear cell carcinoma arising in the prostate. To our knowledge, this type of tumor has not been previously reported to arise in an extrarenal location.     

Adenocarcinoma of the sigmoid segment 38 years after sigmoidcystoplasty : a case report

A 60-year-old woman presented at another hospital with a complaint of voiding difficulty. She had had left nephrectomy and bladder augmentation using the sigmoid colon for treatment of urinary tract tuberculosis 38 years ago. Left ovarian tumor was found by computed tomography and she was referred to our hospital. Another tumor which involved the uterus, bladder, and urethra was revealed by magnetic resonance imaging. An anterior pelvic exenteration was performed with preoperative diagnosis of left ovarian cancer with peritoneal dissemination. Histopathological examination revealed a clear cell adenocarcinoma of the left ovary and a sigmoid cancer arising in the augmented bladder. The sigmoid cancer arose from the anastomotic site between the bladder and sigmoid segment. This is the 34th case of neoplasms following augmentation enterocystoplasty reported in Japan.     

Adenocarcinoma of the ileal segment with transitional cell carcinoma of the bladder following ileocytoplasty: a case report

A 67 year-old woman visited our hospital complaining of pollakisuria. She had undergone left nephrectomy and augmentation ileocystoplasty for tuberculous bladder atrophy 40 years previously. She underwent a total cystectomy and tubeless ureterocutaneostomy with a preoperative diagnosis of muscle-invading transitional cell carcinoma of the bladder. The pathological diagnosis was adenocarcinoma of the ileal segment and transitional cell carcinoma of the original bladder. This is the first case report of adenocarcinoma of the ileal segment and transitional cell carcinoma of the original bladder among 22 patients suffering from bladder cancer after ileocystoplasty.     

Nuclear p53 Overexpression in Bladder, Prostate, and Renal Carcinomas

Background :
The aim of this study was to examine nuclear p53 overexpression in transitional cell carcinoma of the bladder, adenocarcinoma of the prostate, and renal cell carcinoma.
Methods :
Forty-four pathologic specimens from 39 bladder cancer patients, 41 prostatic adenocarcinoma, and 39 renal cell carcinoma specimens were analyzed immunohistochemically with D07 monoclonal antibody to detect the expression of the mutant p53 gene. Overexpression was said to occur when the number of positively-stained tumor nuclei were≥ 10% in each specimen. p53 overexpression was correlated with the clinical and histopathological features of these cancers.
Results :
Nuclear p53 overexpression occurred in 18.2% of transitional cell bladder cancer specimens, 12.2% of prostate cancer specimens, and 17.9% of renal cell cancer specimens. Statistical analyses showed that grade, vascular invasion, and necrosis in bladder cancer, a high Gleason score in prostate cancer, and the 1-year mortality rate in renal cancer were significantly related with p53 nuclear overexpression (P<0.05).
Conclusion :
Using the D07 monoclonal antibody, nuclear p53 overexpression is relatively uncommon in urologic malignancies, and moderately correlates with several histopathological and clinical features of urologic malignancies.     

Two cases of renal cell carcinoma accompanied with ossification]

We report two cases of renal cell carcinoma accompanied with ossification. Case 1: A 40-year-old male visited a physician with the complaint of epigastric pain. Examination of the stomach revealed compression of the greater curvature. Abdominal radiography and CT scan revealed a left renal mass with calcification, which was a hypovascular tumor on angiography. A transperitoneal left nephrectomy was performed. The resected kidney was 700g in weight and the tumor, which was 12 x 10 x 10 cm in size and located in the upper pole of the kidney, was enveloped with a hard capsule and was extensively necrotized. Histopathological diagnosis was renal cell carcinoma (papillary type, mixed subtype). Case 2: A 69-year-old female was occasionally pointed out to have a left renal mass in ultrasonic examination. It was accompanied with calcification in CT scan and a hypervascular tumor in angiography. A transperitoneal left nephrectomy was performed. The resected kidney was 320 g in weight and the tumor located in the lower pole of the kidney, was 6 x 6 x 6 cm in size and necrotized. Histopathological diagnosis was renal cell carcinoma (alveolar type, clear cell subtype). Microscopically in both cases, ossified tissue existed among the fibrous tissue in the necrotized lesion of the tumor, but not near the cancer cells and, it was accompanied by calcification. During the ossification process, the connective tissue proliferates after the necrosis of the tumor, and metaplasia occurred from its juvenile plastic cells to osteoblastic cells.     

A case of bladder metastasis of renal cell carcinoma: a case report and literature review

The patient was a 74-year-old man. Computed tomography (CT) detected a right renal tumor with paraaortic lymph node swelling. Radical nephrectomy and left lymphadenectomy were performed in September 2008. Interferon-alpha (6 million international units three times per week) was administered as adjuvant therapy. Due to the development of side effects, including fatigue, the patient's immunotherapy was discontinued after 6 months. Radiofrequency ablation for pulmonary metastasis was performed 9 months after surgery. A nodular pedunculated tumor was detected on the posterior wall of the urinary bladder by CT, and transurethral resection was performed 18 months after nephrectomy/lymphadenectomy. Since the pathological diagnosis of the bladder tumor was clear cell carcinoma, that tumor was thought to have originated from the renal cell carcinoma. We have summarized 43 cases of bladder metastasis of renal cell carcinoma in Japanese patients, including ours.     

Renal cell carcinoma in a horseshoe kidney

A 65-year-old man with pyuria visited our hospital. Physical examination had revealed a mass in the left upper quadrant of the abdomen. Intravenous pyelogram, ultrasonogram, computerized tomography and selective renal arteriogram suggested a hypervascular renal cell carcinoma on the left side of the horseshoe kidney. A left radical nephrectomy with division of the isthmus was performed. The pathological diagnosis indicated renal cell carcinoma consisting of clear cell type without invasion of the capsule or renal pelvis. Treatment with alpha-interferon was started and has continued for six months with no evidence of recurrence. Only 35 cases of horseshoe kidney with a renal tumor have been reported in the Japanese literature. Among them, adenocarcinoma was present in 54.3% of the cases, renal pelvic tumor in 17.1%, and nephroblastoma in 14.3%. While adenocarcinoma in horseshoe kidney is seen less often than normal kidney, there is an increased incidence of both renal pelvic tumor and nephroblastoma.
