Necrotizing Fasciitis Arising From an Enterocutaneous Fistula in a Case of an Appendiceal Mucocele.

An appendiceal mucocele (AM) is a rare tumorous condition of the appendix. Many patients with AM are admitted to the hospital with abdominal pain or discomfort, and many cases are found incidentally. Although the rate of complications in patients with AM is very low, if left untreated, a mucocele may rupture and produce a potentially fatal entity known as pseudomyxoma peritonei. In this paper, we report a case of an 80-year-old man with necrotizing fasciitis arising from an enterocutaneous fistula caused by AM.
