乳头状浆液性囊腺癌是由大量的实体组织构成，并已侵袭至卵巢外。表面可见乳头状突起。由于早期卵巢肿块没有相应的症状和体征，因此当由于腹部增大而检查出来时，许多已经转移了。转移特点是沿腹膜表面的种植性转移。
This ovarian papillary cystadenocarcinoma is mostly composed of solid tissue and has invaded outside of the ovary, with papillations seen over the surface. Because there are no early signs or symptoms with masses in the ovary, many of these ovarian tumors have metastasized by the time they are detected with abdominal enlargement. These neoplasms characteristically spread by "seeding" along peritoneal surfaces.
