title: [Mucocele of appendix-report of three cases].
abstract: Mucocele of appendix comprises 0.07%-0.3% of the resection of appendix. Three such cases were encountered over the past four years at MMH. Tumor mass could be palpated before operation in two of our cases. The third case was found incidentally during sigmoid cancer resection. Mucocele of the appendix should be differentiated from submucosal lesion such as leiomyoma, lipoma, lymphoma in the cecum or appendiceal abscess. Recent advances of ultrasound, CAT scan as well as angiography have made correct preoperative diagnosis possible, yet literature still shows diverse opinion about its etiology (neoplastic vs. obstructive). Although most authors favor simple appendectomy for the management of this disease, some surgeons still think it should be managed aggressively with colectomy. Rupture of mucocele might result in pseudomyxoma peritonei and possibly a fetal outcome. Avoidance of iatrogenic rupture of appendix is essential. Aggressive removal of accessible masses and implants was suggested in the literature.
