[Mucinous adenocarcinoma of the urachus and peritoneal pseudomyxoma].

The adenocarcinoma of the urachus is very rare tumor, with an incidence of 1/5.000.000 inhabitants, represents less than 0.001 of all types of bladder cancer. Peritoneal pseudomixoma is a rare neoplasm characterized by mucinous acites that involvement the peritoneal surface and omentum. Usually is associated with benign o malignant mucinous tumor of the appendix or ovary. In this paper, we present a case of peritoneal pseudomixoma caused by a mucinous adenocarcinoma of the urachus.

[Second resection in patients with Ta-T1 bladder tumors].

OBJECTIVES: To study the incidence of "residual/recurrence" tumor after a second bladder resection (2nd TUR). METHODS: 40 patients with new or recurrent superficial bladder tumor underwent repeat transurethral resection within 3 months after the initial resection. 37 patients were staged as Ta-T1. We study the incidence of tumor after the 2nd TUR both macroscopically detected or included in the bladder scar. We also study the influence of possible factors as the time between both resections, stage, grade, number of tumor size, localization in the bladder, primary or recurrent tumor and tumor pattern. RESULTS: After the 2nd TUR we found tumor in 14 of 37 (37.8%) Ta-T1 bladder tumors. Among the 14 tumors, 10 (71.5%) were macroscopically visible tumors and 4 cases the tumor were found after resection of the bladder scar of the first resection. We did not find relation between the presence of tumor in the 2nd TUR and any of the variables. CONCLUSIONS: After a TUR of superficial bladder tumor the complete removal of tumor is not always achieved. The early 3 months cystoscopy may not find residual tumor. Although we have found tumor in 37.8% in the 2a TUR we can not recommend routine 2nd TUR in superficial bladder cancer.

[Congenital bladder diverticulum and Ehlers-Danlos syndrome: an unusual association].

The existence of a vesical diverticulum in the context of a congenital connective tissue disorder such as Ehlers-Danlos syndrome led us to consider the possibility of a relationship. Four types of diverticula can be found in the literature: congenital, acquired, iatrogenic and syndrome-associated. Within the later, Ehlers-Danlos syndromes type IV and IX, even type V, are associated to the existence of vesical diverticula. The potential spontaneous rupture of the diverticulum is a typical feature, as well as post-surgery relapse. The attitude towards such diverticula should be one of watchful waiting, and simple, plasty-free diverticulectomy on the bladder's neck is indicated when performing a surgical procedure.

[Mullerian-type papillary serous tumor: exceptional pathology of the testis. Report of a case and discussion].

Within the exceptional tumoral pathology of the testis and paratesticular region are the common epithelial type tumors. Although, its histogenesis is under discussion, it has been interpreted as arising from the remnants of the müllerian duct, or from the mesothelium of the tunica vaginalis differentiating in a müllerian direction. Similarities with homologous ovarian tumors are well recognized and in generally we accept a good prognostic due to its low malignant potential or borderline type, more experience with these uncommon lesions is necessary to evaluate their biologic potential.

[Transitional carcinoma of the prostate].

Case report of prostate transitional carcinoma diagnosed by transurethral resection, an infrequent tumour with incidence ranging from 1% to 4% of all prostate neoplasias which appears in 2.8% of all radical cystoprostatectomies specimens carried out at the Mayo Clinic. Most commonly, when it appears in the prostate this tumour is simultaneous or subsequent to other transitional carcinoma arisen in other organs mostly the bladder. Very rarely it occurs as an early form within the ducts and even less often within the prostate acinus. Review of the neoplasia histology, signs and symptoms, diagnostic procedures and management, emphasising the aggressiveness of its behaviour (such as in our case report) when the prostate gland stroma is infiltrated by the tumour.

[Testicular tumors: our experience].

OBJECTIVE: To report our series of testicular tumors diagnosed from June 1990 to June 1998. The diagnostic protocol, treatment and follow-up are described and data on patient survival over the 8-year period are presented. METHODS: Our series comprised 21 testicular tumors; 19 germ cell and two non-germ cell tumors. There were 5 seminoma, three pure embryonary carcinoma, two mature cystic teratoma, 9 mixed germ cell tumor and two lymphoma. Treatment was by orchidectomy plus radiotherapy, chemotherapy and some cases were closely followed. RESULTS: All 5 patients with seminoma are currently tumor-free, for a mean survival of 38.6 months. Of the 14 non-seminomatous tumors, there were two deaths; the remaining patients are in complete remission, for a mean survival of 37.5 months. The overall survival rate was more than 95% at a mean follow-up of 48 months. CONCLUSIONS: Testicular tumor is one of the most common tumors in young male patients; germ cell tumors are the most frequent type. The different therapeutic regimens currently available have achieved a 5-year survival rate of more than 95%.

[Detubularized ureterosigmoidostomy (Mainz pouch II). Review and contribution of our results].

We have revised the urinary diversions made through the Mainz Pouch II technique in those patients who needed a radical cystectomy because of a neoplastic disease. We will point out the pre and post operatory manometric studies realised in all of them as well as the different complications which were found. In our opinion, the pressure advantages that such technique is supposed to prove have not succeeded in our studies, that is the reason why we believe that a future research is needed to endorse such operatory modification.

[Bladder hemangioma: a clinical case].

Contribution of a new case of vesical haemangioma in a 65-year old male. This is a benign and very rare tumour with not even 90 cases described in the urology literature to date. Haematuria was reported in all cases. This paper presents a review of the literature and a discussion of clinical and pathological features as well as diagnostic methods and recent changes in management approach.

[Paratesticular neoplasms of mesenchymatous origin. Clinico-pathologic study].

There is a group of malignant intrascrotal tumours which represent a very small number when compared to testicular neoplasias and which are known as paratesticular neoplasias. More than 90% belong to the sarcomatous species. From a clinical point of view and based on the patient's age, two groups can be distinguished: sarcomas affecting children and adolescents (primarily rabdomiosarcomas) and those occurring in adulthood, the more frequent histopathological variants being fibrosarcoma, leiomiosarcoma and liposarcoma. This work contributes five paratesticular sarcomas (two rabdomiosarcomas, one liposarcoma, one leiomiosarcoma and one fibrosarcoma). The features related to histogenesis, diagnosis (revealing signs and clinical examination), natural history (dissemination routes based on histopathology) and treatment are reported. With regard to treatment, both the local surgery (total orchiectomy by inguinoscrotal approach with or without hemiscrotectomy), and indications for lymphadenectomy and radiotherapy in relation to staging are discussed though insisting on the chemotherapy approach.

[Clinical features, diagnosis, and treatment of tumor lesions arising in the adrenal gland].

Between 1981 and 1993, 14 patients with tumoral adrenal disease were diagnosed and treated in the Urology Services of both Hospitals. Nature of the adrenal disease was functional in 8 patients (two carcinomas and six pheochromocytomas) and non-functional in the rest (three carcinomas, two adenomas and one myelolipoma). Reference is made to the clinical manifestations and laboratory tests related to hormonal activity, depending on whether the tumour is functional or non-functional, chromaffin or non-chromaffin. Patients with functional carcinomas had Cushing's syndrome, with very clear virtilization signs. Urine 17-hydroxycorticosteroid, 17-cetosteroides and cortisol were all increased, same as plasma cortisol. Patients with pheochromocytomas had hypertension and headaches (six patients), sweating (five patients), anxiety (four patients) and loss of weight (two patients). All of them had increased urine vainillylmandelic acid and catecholamines. Clinical signs and symptoms of non-functional tumours were related to bulk growth and size (in the three carcinomas), and sometimes was highly anodyne, or even absent (in the two adenomas and the myelolipoma), the cause of discovery being accidental during an ultrasound examination. An analysis is made of the different imaging diagnostic procedures performed, such as IVU (performed in 13 patients) with a 38.4% resolutory power; ultrasound (performed in 11 patients) with an 81.8% resolution; CAT (performed in 6 patients) with a 100% resolution capacity and arteriography (performed in 3 patients) with a 100% resolution power, although patients had previously undergone ultrasound and CAT.(ABSTRACT TRUNCATED AT 250 WORDS)

[Bladder carcinosarcoma: case report with immunohistologic study].

We present a new case of carcinosarcoma of the bladder. This tumor is generally considered to be a rare one, has an uncertain aetiology and very poor prognosis, composed by mesenchymal and epithelial elements. It is an aggressive tumor with a short clinical course. At present radical cystectomy is the treatment of choice.
