We report a case of prostate carcinoma metastatic to the mandible that had been initially suspected as being a primary carcinoma of the parotid with lymph node metastasis. The present case underscores the diverse forms of manifestation of prostate carcinoma.
In the context of a misleading diagnosis of paraurethral abscess, we report a case of unrecognized metastatic squamous cell carcinoma of the male urethra that mimicked a picture of paravertebral abscess with accompanying massive caval vein thrombosis. Fine needle aspiration cytology of both paravertebral abscess and urethral nodule allowed the diagnosis. This report calls the attention of clinicians to think of a malignant process in case of a paravertebral abscess. Fine needle aspiration cytology once more proves a useful tool in the diagnosis of unsuspected malignancies.
Display of the clinico-pathological correlation of three cases of adenomatoid tumour (AT) of the male reproductive organs. From the anatomo-pathological point of view we observe the architectural patterns traditionally described, and discuss their controversial mesothelial origin. From the clinical point of view we highlight the benignancy of the process, often underdiagnosed, as well as its association to post-inflammatory hydrocele in one case. Such coincidence could favour the assumption that inflammation plays a decisive role on the production mechanism.
Presentation of a new case of synchronic concurrence of renal adenocarcinoma and papillar carcinoma of renal pelvis on the same kidney. The origin of this double malignant renal tumour remains unknown, although several hypothesis have been raised. We believe that coexistence of both tumours is more than casual and we would underscore the morphogenetic interpretation of such coincidence.
Kaposi's sarcoma of the penis is an initial manifestation of AIDS and the practising urologist should be aware of this form of presentation. We report 2 young intravenous drug abusers with this tumor in the male genitourinary system. The clinical course is unfavorable; therefore prompt diagnosis and management, based on the early recognition of the lesion, must be achieved.
A 61-year-old man presented with macroscopic haematuria. Infiltrating transitional cell carcinoma of the urinary bladder was diagnosed after transurethral resection, and he was treated first with three doses of cisplatinum (100 mg/m2 at three week intervals) and then by radical cystectomy. Eleven months later he complained of progressive diplopia, which was found on computed tomography to be caused by a retro-orbital metastatic mass. There was no evidence of a space occupying lesion in the brain or of other metastases. The patient died four weeks later and permission for necropsy was refused. Despite the fact that carcinoma of the urinary bladder rarely metastasis in this way, urologists should be aware that it can happen.
We report a complicated case of renovascular hypertension from bilateral atherosclerotic renal artery stenosis in a solitary functioning kidney. Percutaneous transluminal angioplasty (PTA) was performed after diagnostic arteriography. Hypertension remitted only after surgical removal of the nonfunctioning kidney. In our view, PTA is the procedure of choice even in the solitary kidney.
We report two cases of bladder leiomyosarcoma diagnosed by histology. Total segmental cystectomy was performed in both cases because of the scant progressive nature of the disease. A follow up of 11 and 6 years, respectively, revealed no tumor recurrence or metastasis. The choice of performing a conservative or radical surgical procedure in the treatment of this tumor type should depend on the endoscopic findings as well as tumor grade and stage.

We present two cases of thromboses of the left renal artery out of a total of 74 kidney traumatisms observed up to 1978. In one of them, accompanied by arterial hypertension, the tension readings returned to normal after a nephrectomy. Following a review of the literature, in which we observe the infrequency of this pathology (38 cases compiled by R. Fay and S. Brosman up to 1974), we comment upon the etiopathogeny, clinical characteristics, specific radiological signs and other means of exploration which enable the diagnosis to be reached. We point out the importance of an early diagnosis and the conservative and radical forms of surgery.
