[Amyand hernia--a rare anatomic and clinical entity diagnosed intraoperatively].

The Amyand hernia is an uncommon variant of the inguinal hernia, rarely recognised before the surgical treatment because of the confusion with a strangled hernia. In spite of this, the clinical presentation seems to follow a well determined pathway, so it is possible to state that the uncorrect diagnosis is to be attributed to the ignorance of this variant of hernia. We present two consecutive case reports of acute appendicitis founded in an inguinal hernia sac.
