Malakoplakia is a rare entity on inflammatory base that mostly occurs in immunocompromised individuals which is thought to be secondary to a bactericidal defect in macrophages. The genitourinary tract is typically affected. The appendix is a very rare localization. We report a case of malakoplakia in the appendix of a young healthy patient with a recent history of abdominal pain associated with diarrhea and nausea. The colonscopy and CT scan showed an extramucosal bumping mass pressing on the cecum and covered by normal mucosa. The patient underwent to laparoscopic appendectomy. The histology showed a malakoplakia of the appendix. Gastrointestinal localization of malakoplakia is often associated with preexisting diseases, which are probably responsible for an immune disorder underlying the etiopathogenesis of the disease. However, in our case, the patient had no comorbidities. Probably, a clinically unknown immune predisposition plays an important role. Further studies are needed to clarify this nexus.
