title: Appendicovaginal fistula and primary appendiceal cystadenocarcinoma.
abstract: An elderly woman had an appendicovaginal fistula. Within the appendix was a well differentiated mucin-producing cystadenocarcinoma that extended through the fistula and onto the vaginal mucosal surface. The development of this fistula was probably related to the tumor and a previous hysterectomy, which allowed close proximity of the tip of the appendix to the vaginal vault.
