These cases clearly illustrate the importance of communication between the pathologist and gynecologist or gynecologic oncologist to deliver optimal patient care. It is not only important for the pathologist and gynecologist to review the pathologic diagnosis before implementing treatment plans, it is also imperative that the gynecologist provide the pathologist with a thorough history. As part of this communication process, the pathologist conveys abnormalities of histology as well as uncertainties, such as that which occurred in the mucinous cystadenocarcinoma case. By maintaining open communication, the patient receiving gynecologic treatment will receive the best possible care.
