The histopathological diagnosis and treatment of borderline epithelial tumo
rs of the ovary (BTO) still pose problems to both pathologists and gynecolo
gists. BTO is a disease of younger, fertile females and generally has an ex
cellent prognosis. A minority of patients, however, succumb to this disease
. A review of the literature is given addressing aspects of epidemiology, h
istology, treatment and prognosis, resulting in a proposal for the manageme
nt of serous and mucinous borderline tumors of the ovary.
