@entity43 (BOT) are distinctive from @entity5 . They occur in younger @entity1 more often than @entity189 , and there is some difficulty making correct diagnosis of BOT. Two subtypes of BOT, serous and mucinous borderline @entity5 have different characteristics and very different clinical behavior. Serous borderline @entity5 (SBT) with micropapillary pattern shows more incidence of extra @entity2670 and often coexists with invasive implant. SBT with micropapillary pattern in advanced stage has showed a worse prognosis than typical SBT. Huge mucinous borderline @entity5 have histologic heterogeneity, and the accuracy of frozen section diagnosis is relatively low. Extensive sampling is required to reach a correct pathological diagnosis. @entity652 (intestinal type) also runs the risk of recurrence after cystectomy, or intraoperative rupture of cyst. Laparoscopic procedure for BOT has not increased the risk of recurrence. Fertility preserving procedures are generally accepted, except in advanced stage SBT with invasive implants. Only cystectomy shows a significant risk of recurrence. Re-staging surgery and full staging surgery is not necessary for all BOT. We should not attempt to treat them uniformly, by the single diagnosis of "borderline @entity5 ". It depends on histologic type. Close communication with the pathologist is necessary to gain more detail and ask more pathological samples in order to make the optimal treatment strategy for each individual @entity1 .
