Mucous cystadenomas are benign epithelial tumours with great mucous content inside. Despite being non-malignant, they acquired great size, compressing and displacing important structures and organs of the zone, with theirs unlucky outcomes. Surgical exeresis is very difficult, being almost impossible its total exeresis, showing great frequency of relapse. We present an appendix mucous cystadenoma case in a 54 years old patient.
We report a case of a 77 years old woman with an previous malignant melanoma, who presented an urethral metastasis. The disease was treated with conservative therapy by local excision after pedicle ligation, and she is free of symptoms after one 1 year of control.
We report the case of a 31 year old male, with lower urinary tract symptoms. We achieved the diagnosis of an prostate angiosarcoma. The treatment was a retropubic radical prostatectomy and partially resection of bladder neck, followed by chemotherapy with Ifosfamide and Adriamycin. At least 36 months up to surgery the patient is alive and free of symptoms and radiological signs of recurrence.

We report a case of female 24 years old who had a blunt abdominal trauma. The immediate consequence was the radiological evidence of a left kidney abolition, secondary to a renal artery thrombosis. The treatment was conservative, and there was not a surgical procedure.
Nephrogenic adenoma is a rare urothelial neoformation. It is well known the association to infective diseases and stones; the most common localization is in the bladder. We report the case of a young male without previous disease who showed a nephrogenic adenoma in the urethra, it was managed with transurethral resection and surveillance.
Castleman's disease (angiofollicular hyperplasia of the lymphatic nodes) can exceptionally appear as a retroperitoneal mass of difficult differential diagnosis relative to other malignant retroperitoneal masses. Because of its rarity, one case report of a retroperitoneal mass with histologic study corresponding to Castleman's disease is contributed. A revision of the different histologic varieties of Castleman's disease, specific treatment and prognosis is included.
The indications for repeat prostate needle biopsy after a previous biopsy are not defined. We examined 107 prostate biopsies (in 98 patients) without a diagnosis of malignancy, which we repeat. Carcinoma was detected in 31 patients (31.6%). We didn't find statistic relationship between the repeat biopsy's outcome and: interval between biopsy and repeat biopsy, PSA value, PSA density (biopsy), PSAD of the transitional area (PSAD ad., on repeat biopsy). We found relationship with: prostatic weight (p = 0.002 on the biopsy, p = 0.0002 on the repeat biopsy), volume of the transitional area (p = 0.02 on the biopsy, p = 0.0001 on the repeat biopsy), PSA value (p = 0.02, on the repeat biopsy), PSAD ad. (p = 0.002, on the repeat biopsy), and with PSA velocity (p = 0.008). We only found clinic usefulness for the PSA velocity: patients with PSA velocity greater than 1 ng/ml/year are at high risk for prostate carcinoma on the repeat biopsy, specially in small prostates.
Incrusted cystitis is an infrequent process characterized by precipitation an incrustation of salts on the vesical mucosa. An alkanine urine is required to this precipitation. The urinary infection with urolithic activity microorganisms can also be a very important factor. We present a case of incrusted cystitis after using Mitomicine as vesical chemotherapy.
