Villous adenoma causing acute appendicitis

Acute appendicitis is the most common of surgical emergencies. However, it is very unusual to find a benign neoplastic lesion causing appendicitis. Adenomas of the caecum or the appendix are rare and very few cases of these associated with appendicular inflammation have been described. This report presents a case of acute appendicitis with perforation resulting from obstruction by an adenoma. The management of the condition is discussed.
