Testis tumours usually emerge in young patients as a painless increase in the testis size accidentally noticed by the patient. Contribution of one case of non-seminomatous testis tumour which presented clinically as an acute scrotum. An exhaustive appraisal of the clinical data allowed to choose the most appropriate approach for the patient in an emergency situation.
By definition, the term paraganglioma includes all the tumours deriving from the body's paraganglion system, which are therefore ranked as intra-adrenal (pheochromocytoma) and extra-adrenal or paraganglion. Vesical paraganglion represents about 10% of all extra-adrenal paraganglioma and can be functional and non-functional. When functional, the symptoms are those originated from the products synthesised in excess, usually occurring in a paroxismical fashion, in relation with urination, ejaculation and defecation. Contribution of one vesical paraganglioma accidentally found in a 71 year-old female patients undergoing tests to study the extent of a right kidney carcinosarcoma.
The inverted papilloma of the urethra is an exceptional entity. It occurs as a smooth surface, sessile tumour located in the prostatic urethra. Microscopically, it is lined with transitional epithelium which is projected inside the tumour, creating strands of cells with normal characteristics. All cases reported up to now have occurred in men aged between 49 and 79. None of the cases had additional urothelial injuries associated. Contribution of a new case of inverted papilloma of the prostatic urethra in a 52-year old male. Transurethral resection of the tumour was the procedure chosen. Evolution was good and no relapse nor further urothelial injuries were observed at the controls carried out over an 8-year follow-up period.
Using a sample of 41 patients, diagnosed with prostate adenoma, an estimate was made on the degree of correlation between the weight of the adenoma as predicted through abdominal ultrasound scan (x) and the actual weight after surgical removal (y). An experimental principle or mathematical formula has been worked out to translate that correlation and it allows the urologist to appraise the adenoma's actual weight as related to the ultrasound scan weight. The degree of correlation between the ultrasound-estimated weight and the actual weight was high (0.85) and statistically significant (p < 0.01). The experimental principle of mathematical formula which will allow the urologist to make a closer approximation to the actual weight of adenomas studied by ultrasound was y = 0.93 * x + 4.7.
