[Focal infarction of the testis. Report of a case simulating a gonadal mass]

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.
