The presence of a vermiform appendix in an inguinal hernia is known as Amyand's hernia. It is rare condition that occurs in about 0.51% of the cases of inguinal hernia. Appendicitis within an Amyand's hernia is found in 0.10% of all forms of external hernia sacs. It is often misdiagnosed as a strangulated inguinal hernia. We experienced a case of Amyand's hernia with a periappendicular abscess within a right inguinal hernia sac in a 71-year-old male patient. Combined appendectomy and Bassini's herniorrhaphy were performed. The patient had an uncomplicated postoperative course and he was discharged 8 days after admission.
