Perforated appendicitis in an incarcerated scrotal hernia--a case report.

A 72-year-old man in whom perforated appendicitis developed within an incarcerated scrotal hernia sac is presented herein, because of both its rarity in the literature and the difficulty encountered in establishing a diagnosis. If such an infection is limited to within the hernial sac, the prognosis is benign, however, the presence of peritoneal contamination affects the prognosis negatively. Moreover, there is no supplemental risk in performing a primary hernia repair following appendectomy in the same session.
