[Necrosis of undescended testis caused by incarcerated inguino-scrotal hernia in a newborn].

Presentation of an uncommon case referring necrosis of an ectopic inguino-femoral testis caused by an incarcerated inguino-scrotal hernia in a 15-days old baby with a permeable peritoneum-vaginal process. In this case, the hernial incarceration episode was responsible for the organ necrosis due to an haemorrhagic infarction. Orchiectomy was performed, and the pathoanatomical diagnosis was testicular haemorrhagic infarction. Review of the pathogenic mechanisms of testicular ectopia, associated anomalies and likely acute complications: torsion, hernial strangulation, traumatism and infections simulating acute abdomen which, in spite of their rarity, may have serious consequences with regard to testicular viability.
