When it comes to the therapeutic options in these cases, the initial trend was to adopt the same strategy as in cases presenting invasive mucinous lesions. However, studies conducted so far cam to demonstrate that the appendix presented tumoral infiltration in an extremely low number of cases especially if a normal macroscopical aspect was present and therefore routine appendectomy was no longer recommended. The aim of the current paper is to investigate in which cases appendectomy should still be part of the therapeutic strategy in mucinous borderline ovarian tumors.
