[Focal infarction of the testis. Report of a case simulating a gonadal mass]. / Infarto focal del testículo. A propósito de un caso que simulaba un proceso expansivo gonadal.

Series of comments on the clinical history of one patient diagnosed "a posteriori" with a focal infarction of the testis. The case was pre-operatively handled as a tumour, as a result of which the patient underwent radial orchiectomy. The only notable feature in the patient's background was a vasectomy, performed two years earlier. The rationale for this communication is the rarity of this entity and the differential diagnosis to be practised. Reference is made to some complementary diagnostic tests that may be requested. It includes a number of considerations on testis vascularization. After reviewing some studies contributed by the Spanish literature, several complications to be taken into consideration when performing a vasectomy are explained.

[Hypertrophy of Bertin's columns]. / Hipertrofia de las columnas de Bertin.

Description of 17 cases of columns of Bertin's hypertrophy found by chance while performing 587 urological ecographies carried out while following other urogenital diagnostic approaches. The present report is prompted by the entity's features and the differential diagnosis forced by the "renal mass effects". A series of reflections are built on the various supplementary tests that can be performed.

[Aberrant renal papilla. 2 new case reports. Diagnostic considerations]. / Papila renal aberrante. Dos nuevas aportaciones. Consideraciones diagnósticas.

Another two cases of aberrant renal papilla are described. These had been diagnosed following an IVP procedure and corroborated by ultrasound. One patient had presented with prostatism and the other had consulted for episodes of renal colic. Because a differential diagnosis is mandatory to distinguish this uncommon condition from other filling defects of the renal pelvis and particularly from false aberrant renal papilla, we were prompted to report on these two cases.
