[A case of appendiceal mucocele associated with cancer of the colon].

Mucocele of the appendix is a rare lesion (only 0;2-0.3% of all appendicectomies). It is characterized by distension of the lumen within mucus. Mucoceles are often asymptomatic and are discovered as an incidental finding either at surgery or during barium edema. There have been reports of other tumors associated with adenomatous change in the appendix. The most common association was with adenocarcinoma of the colon, which occurred concurrently in approximately 20% of patients. Preoperative diagnosis is rare. The therapy is surgical; or appendicectomy in the benignant lesions of right colectomy in the malignant lesions. The authors report a case of appendiceal mucocele associated with adenocarcinoma of the colon. That was occasionally observed during emergency laparotomy in perforation of cave viscer. We discuss problem that appear from the association of these two pathologies.
