Ovarian Epithelial Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Cellular Classification of Ovarian Epithelial Cancer

The following is a list of ovarian epithelial cancer histologic classifications.

  • Serous cystomas:
    • Serous benign cystadenomas.
    • Serous cystadenomas with proliferating activity of the epithelial cells and nuclear abnormalities but with no infiltrative destructive growth (low potential or borderline malignancy).
    • Serous cystadenocarcinomas.
  • Mucinous cystomas:
    • Mucinous benign cystadenomas.
    • Mucinous cystadenomas with proliferating activity of the epithelial cells and nuclear abnormalities but with no infiltrative destructive growth (low potential or borderline malignancy).
    • Mucinous cystadenocarcinomas.
  • Endometrioid tumors (similar to adenocarcinomas in the endometrium):
    • Endometrioid benign cysts.
    • Endometrioid tumors with proliferating activity of the epithelial cells and nuclear abnormalities but with no infiltrative destructive growth (low malignant potential or borderline malignancy).
    • Endometrioid adenocarcinomas.
  • Clear cell (mesonephroid) tumors:
    • Benign clear cell tumors.
    • Clear cell tumors with proliferating activity of the epithelial cells and nuclear abnormalities but with no infiltrative destructive growth (low malignant potential or borderline malignancy).
    • Clear cell cystadenocarcinomas.
  • Unclassified tumors that cannot be allotted to one of the above groups.
  • No histology.
  • Other malignant tumors (malignant tumors other than those of the common epithelial types are not to be included with the categories listed above).
