[Villous polyp of the urethra].

Villous polyps of the urethra are rare. This condition can be seen more frequently in patients aged 30-40 years. Hematuria is usually the major symptom. Generally, the polyps are localized in or around the verumontanum and do not recur after TUR or electrocoagulation. A case of villous polyp of the verumontanum is described in a patient who presented with symptoms and signs of obstructive micturition. The patient continues to be asymptomatic 6 months following treatment by electrocoagulation.

[Squamous keratinizing carcinoma in diverticulum of the bladder. Long term evolution].

The authors present a case of scaly carcinoma, located in a vesical diverticulum. They analyse the general problems involved in the etiology, clinical picture, histogenesis and treatment of this kind of neoplasia. The prognosis is unfavourable in a high percentage of cases. The personal case which we present progressed very well (3.5 years) after having been treated by means of diverticulectomy and post-operative radiotherapy.

[Mucinous adenocarcinoma of the urachus].

Malignant tumours of the urachus are very rare and they give certain difficulty in their differential diagnosis with vesical cupula adenocarcinoma. We present a case of mucinous adenocarcinoma of the urachus in a 75-year-old patient and we analyse the behaviour, clinical background, diagnosis and treatment of these tumours.

[Sarcomatoid renal carcinoma].

The authors present a case of sarcomatoid kidney adenocarcinome of the fibrosarcomatoid kind. They stress the importance and difficulty of making a differential diagnosis between the sarcomatoid type of kidney adenocarcinomas and pure sarcomas of the kidney, this being an entirely histopathological and extremely complex diagnosis. They comment upon the possible histogenesis in the sense that they may be sarcomatoid areas deriving from the stroma or from a cellular metaplasia of the adenocarcinoma.

[An unusual cause of hematuria: periureteral varicose veins].

A case is presented of periureteral varicose veins which are rare but which constitute a possible cause of recurring hematuria. The authors analyse the general problems of this process, with regard to its etiopathogeny, clinical picture and differential diagnosis. The treatment must be conservative and involves the disappearance of the symptoms.
