Hemangiopericytoma is a rare capillary tumor that was first described and named by Stout and Murray in 1942. A case of hemangiopericytoma in the pelvic retroperitoneum is reported. The patient, a 57 year old man, was admitted because of dysuria. He underwent extirpation of the tumor with the rectum by low anterior resection. The pathological diagnosis was malignant hemangiopericytoma, and Adriamycin was administered to prevent recurrence or metastasis. He has been free from any recurrence or metastasis for the last eight months. Twenty cases of hemangiopericytoma in the retroperitoneum including our case, were collected from Japanese literature and reviews. Hemangiopericytoma, especially in the retroperitoneal space, should be regarded as a highly malignant tumor. Early aggressive therapy and long term follow up are recommended because the tumor characteristically produces late local recurrence and metastasis.

Selective intraarterial infusion of the ethylcellulose microcapsules of mitomycin C (MMC-mc) exerts its potential therapeutic effects through both infarction and prolonged local, drug activity, i.e., chemoembolization. Twenty patients with intractable primary, recurrent or metastatic carcinoma were treated with single or fractionated infusion of MMC-mc via percutaneous arterial catheterization. The target sites were the kidney, liver, prostate, urinary bladder, uterus, sigmoid colon, Douglas' pouch and bone. Fourteen patients had over 30% reduction in measurable maximum tumor diameter, 5 had 10 to 30% reduction and 1 showed less than 10% reduction, but concurrent 2 bone lesions had no reduction. Improvement of symptoms and signs such as pain, massive hemorrhage, dysuria, anorexia and hydronephrosis was observed at an early stage of the treatment in all patients. Eight patients with highly invasive carcinoma of the kidney, urinary bladder and cervix were initially treated with MMC-mc followed by successful radical operation. Systemic toxicity was mild and all patients tolerated the treatment. Although the follow-up periods are less than 21 months, 12 patients are alive with or without tumor and 11 of them are doing well. The present results indicate that chemoembolization with MMC-mc is effective as a preoperative or palliative measure in the treatment of invasive carcinoma of various organs.

A case of carcinoma in urethral diverticulum is herein reported. The patient was a 58-year-old housewife presenting with the complaint of dysuria. Physical examination revealed a hen-egg-sized cystic mass at the anterior vaginal wall. Complete excision of the diverticulum was performed transvestibulary. Pathologically, it was described as papillary adenocarcinoma. The patient's postoperative course was uneventful and she was discharged. She was readmitted because of recurrence of tumor 9 months after the first operation. Forty-five cases including this case are reviewed and discussed.

Herein we report a case of primary paraganglioma of the urinary bladder. A 21-year-old woman was admitted to an emergency hospital, because of gross hematuria, dysuria and complete urinary retention. Pelvic CT scan and ultrasonic examination revealed a bladder tumor and coagulated blood mass, then she was referred to our clinic for further treatment. On cystoscopy a dark brown lobular tumor was seen on the anterior wall. The bladder tumor was removed by partial cystectomy. The operative specimen measured 6 X 4 X 3 cm and weighed 50 g. Histological examination showed it to be a paraganglioma of the urinary bladder, which was chromaffin positive. Her serum and urinary catecholamine level were within the normal range after operation. She is now ten months postoperative, free from hematuria, and showing no other symptoms or signs of disease including metastasis.

A 56-year-old-married woman, gravida 3, para 2, was admitted with chief complaints of atypical genital bleeding, large abdominal and genital tumors, dysuria and abdominal pain. All laboratory examinations were noncontributory. Abdominal total hysterectomy with bilateral salpingo-oophorectomy was performed. The tumor measured 30 X 11 X 8 cm and weighed 1,600 g. It showed polypoid growth and most of the tumor was necrotic. The tumor cells resembled endometrial cells and 20 mitotic figures per 10 high-power fields were noted. Ten months postoperatively, the patient was in good condition with use of PSK.

Thirty-seven patients were enrolled in a randomized prospective study to compare standard surgical therapy for superficial bladder cancer to standard therapy plus bacillus Calmette-Guerin (BCG). Side effects of BCG have been tolerated well and include dysuria in 95 per cent of the patients, urinary frequency in 83 per cent, hematuria in 39 per cent, fever in 22 per cent and nausea in 22 per cent. Of 19 control patients 8 (42 per cent) had recurrent tumors in the followup period, compared to 3 of 18 patients (17 per cent) treated with BCG. One patient treated wih BCG had 2 recurrences, yielding a recurrence rate of 22 per cent in the group receiving BCG compared to 42 per cent in controls. When the incidence of recurrent tumors in matched intervals before and after entry into the protocol is compared, no change in the rate of tumor recurrence (p equals 0.726 chi-square) occurred in controls, whereas tumor recurrences were reduced significantly in the group treated with BCG (p equals 0.010 chi-square). The reduction in tumor recurrence in patients treated with BCG compared to controls is statistically significant (p equals 0.029 chi-square). Of 4 patients who presented with new bladder tumors remain free of tumor after BCG therapy, while 2 of 5 comparable control patients developed recurrent tumors. Intravesical and percutaneous BCG immunotherapy appears to decrease the rate of tumor recurrence in patients followed for 1 year.

The authors study 39 cases of late genitourinary sequelae following abdominopelvic radiotherapy. Several points appear to be of interest: - the mean latent period was 3.5 years for bladder sequelae and 4 years for ureteric complications. Fistulae could develop on average 14 years after radiotherapy; - the possibility of ureteric complications in the form of stenosis after radiotherapy, exclusive of associated surgery; - all lesions were purely due to radiation, excluding recurrences of neoplasm; - bladder complications had striking symptoms with dysuria and haematuria. Ureteric stenosis was sometimes found by chance, being latent; - associated digestive tract radiation lesions were seen in 1 case in 4; - the frequent need for surgery, since this was required in 30 patients out of 39. The operations performed were often extensive; - the grave nature of surgical operations including a digestive phase in these patients who had received large doses of radiation. Peritonitis due to the breakdown of sutures was a notable source of mortality; - one of the great difficulties in investigating such patients is to be able to confirm the purely radiation aetiology of these complications, bearing in mind that amongst urological complications following the treatment of pelvic carcinomas, the majority are related not only to radiation but also to recurrence of neoplasm.

An 8-year-old boy presented with dysuria and acute retention of urine. Rectal examination showed a hard mass arising from the prostate. CT scan of the pelvis confirmed the presence of a large prostatic tumor causing bladder outflow obstruction. A provisional diagnosis of pelvic sarcoma was initially made. Biopsy of the tumor mass however, revealed non-Hodgkin's lymphoma of T-cell type. The tumor showed very good response to chemotherapy and the urinary obstruction significantly improved with a week after starting therapy.

Epidermoid carcinoma is the most frequent neoplasia of the vulva. It usually appears in aged post-menopausal women (51-70 years). The signs and symptoms are unremarkable: vulvar bulk or protuberance, pruritus, painful ulcer, flow, vulvar irritation, dysuria or haemorrhage, all of which motivate that this condition may be ignored, overlooked, or be the cause of self-treatment. At other times a dangerous shyness causes considerable delays by postponing the visit to the specialist. Many patients refuse to go to see a physician. The existence of urinary signs and symptoms in a patient with vulvar neoplasia are indicative of urethral invasion and the advanced stage of the condition. A case is presented here of an advanced vulva carcinoma in an 82 year-old woman who come with urinary retention by urethral infiltration and perineal destruction. We review the most relevant aspects of vulvar carcinomas associated with obstructive uropathy.

We report a case of leiomyoma of the female urethra and review the literature. A mass protruding from the urethral meatus during voiding caused dysuria. Urodynamic study showed an obstructive pattern with low maximum urine flow and high detrusor pressure in initiating voiding. Cystourethroscopy revealed a mass extending from the proximal segment of the left lateral urethral wall into the bladder. At transurethral resection of the tumor 12.2 gm. of tissue were excised. Histopathological studies confirmed urethral leiomyoma. Surgery completely resolved the original symptoms of dysuria.
