[Adenomatoid tumor of the albuginea testis].

We present a rare case of adenomatoid tumour situated in the testicular albuginea. We comment on its treatment, which we are of the opinion should be conservative.

[Transitional cell carcinoma in a retrocaval ureter].

We report a case of duplicated inferior vena cava and right retrocaval ureter with a urothelial tumor. The embryonal, clinical and diagnostic aspects of this disease entity are discussed. CT permitted noninvasive visualization of the retrocaval ureter and the urothelial tumor. We underscore the usefulness of the foregoing imaging technique versus the more invasive techniques such as cavography and ascending pyelography.

[Xanthogranulomatous pyelonephritis: apropos of 13 cases].

We present 13 patients anatomopathologically diagnosed with xantogranulomatose pyelonephritis. This form of inflammatory reaction may give rise to major pre-operative diagnostic difficulties through being confused with renal neoplasias. Clinical evolution consists of long-developing lithiasis complicated with infection. We regard echography and C.A.T. as extremely useful elements both in accurate pre-operative diagnosis and in the locoregional evaluation of the lesion. Treatment is surgical and the prognosis is favourable.

[Torsion of the spermatic cord].

We report on 55 cases of torsion of spermatic cord. We describe the clinical features and the findings on physical examination as well as other factors such as patient age, past history of transient painful episodes which should prompt us to consider this condition. In our view, immediate surgical exploration is justified in all cases of acute scrotum in patients in the second-third decade of life in whom this condition is suspected. This approach has allowed us to achieve testicular salvage in 76% of the cases immediately postoperatively. Contralateral fixation is mandatory. The possibility that unilateral testicular torsion might cause subsequent infertility from lesion to the contralateral testis probably due to an autoimmune mechanism has led to a reconsideration of radically conservative management of testicular torsion. Testes whose viability is doubtful should be removed. If untwisting and fixation is performed, patients should be followed closely for a long period to evaluate patient fertility.

[Angiosarcoma of the kidney].

A case of renal angiosarcoma is presented. The extremely unusual frequency of this entity, its clinical and pathological features, and mode of presentation accompanied by intense intratumor hemorrhage, a unique finding compared to other cases of renal angiosarcoma thus far reported, have been highlighted.
