[Paratesticular rhabdomyosarcoma].
Report of one paratesticular RMS in a 28 year-old male. The paper includes a review of the various clinical, etiopathogenic and therapeutic features involved. RMS is a neoplasia difficult to diagnose through M.O. and, quite often, it is necessary to use immunohistochemical techniques in order to discover some of the muscular fibre markers, such as Desmin, Myosin and Myoglobin. Several theories have been put forward to explain its origin, and the most widely accepted defends an origin in a poorly differentiated mesenchymal tissue. The advantages of retroperitoneal lymphadenectomy following orchiectomy are discussed as treatment.

[Skin metastasis in external ear canal of bladder carcinoma].
A case of vesical carcinoma skin metastasis in the external ear is presented. Apart from its uncommonness, cutaneous dissemination of a vesical carcinoma implies a poor prognosis since it is indicative of metastasis spreading to other sites, death occurring in nearly all cases within three months of diagnosis.

[Calcified renal carcinoma. Diagnostic difficulty].
Two cases of renal carcinoma presenting as renal cyst seen at our service in the past year are described. One presented as a large central cyst with several smaller cysts on its wall. The other presented as a renal cyst coexisting with several serous cysts. Imaging techniques are underscored due to the diagnostic difficulties. The currently available diagnostic techniques for classifying tumor masses with mixed or undefined features are briefly described.

[Antibiotic prophylaxis in endoscopic urologic surgery].
Recent studies have shown the value of antibiotic prophylaxis with short therapy periods in patients submitted to transurethral surgery. We have carried out a prospective study on 46 patients, all with negative urine cultures prior to the intervention, divided into two groups: one control and the other with short cefuroxime prophylaxis. With the latter a reduction in post-operative infectious complications was obtained, and specifically of postoperative bacteriuria, from a 70% in the control group to al 13% in the prophylaxis group. The results are statistically significant.

[Complex renal lithiasis: conservative surgery].
We report a case of complicated renal lithiasis which had been successfully treated by conservative surgery. The present case shows that this surgical procedure continues to be a valid therapeutic option for this pathology, although occasionally the new, less invasive treatment modalities that continue to develop are utilized in the treatment of renal lithiasis far beyond the indications.
