Gross pathology of an ovarian carcinoma.

Ovarian tumors, or ovarian neoplasms, are tumors arising from the ovary. They can be benign or malignant (ovarian cancer). They consist of mainly solid tissue, while ovarian cysts contain fluid.

Histopathologic classification

Ovarian tumors by incidence and risk of ovarian cancer

Ovarian tumors are classified according to the histology of the tumor, obtained in a pathology report. Histology dictates many aspects of clinical treatment, management, and prognosis.

The most common forms are:

Type Subtype Relative incidence Percent malignant Comments Micrograph
Germ cell tumor Mature cystic teratoma 46.0% 0.17% to 2% Cystic, with elements of all 3 germ layers (endoderm, mesoderm and ectoderm).
Hair follicles.
Immature teratoma 2.5% 100% A teratoma that contains anaplastic immature elements, and is often synonymous with malignant teratoma. Histopathology of immature teratoma of the ovary.jpg
Other germ cell tumors 3.0% Others mainly include dysgerminoma, yolk sac tumor, struma ovarii and squamous cell carcinoma arising from a dermoid cyst, and malignant mixed germ cell tumor.
Surface epithelial-stromal tumor Serous tumor 25% 18.5% Benign serous tumors of the right ovarian cyst are thinwalled unilocular cysts that are lined by ciliated pseudostratified cuboidal or columnar epithelium. Histopathology of lining of a benign serous tumor of the ovary.jpg
Mucinous tumor 15% 8.8% Benign mucinous tumors of the ovary consist of simple, nonstratified columnar epithelium with basally-located hyperchromatic nuclei and resemble gastric foveolar epithelium. Histopathology of lining of a benign mucinous tumor of the ovary.jpg
Endometrioid tumor 1% Almost 100% Tubular glands, resembling endometrium. Histopathology of well-differentiated endometrioid adenocarcinoma.png
Other surface-epithelial tumors 1.5% Others include mainly malignant mixed mullerian tumor, Brenner tumor and mixed epithelial tumor.
Sex cord-stromal tumor Ovarian fibroma 1.5% 0% Spindle-shaped fibroblastic cells and abundant collagen. Histopathology of an ovarian fibroma.jpg
Adult granulosa cell tumor 1% Almost 100% Small, bland, cuboidal to polygonal cells in various patterns. Granulosa Cell Tumor of the Ovary (5621714007).jpg
Other sex cord-stromal tumors 1% Others include mainly juvenile granulosa cell tumor, thecoma and sclerosing stromal tumor
Secondary/metastatic) tumor 2% 100% Usually from breast cancer, colon cancer, endometrial cancer, stomach cancer or cervical cancer.

Mixed tumors contain elements of more than one of the above classes of tumor histology.

History

An 1882 article appearing in Scientific American mentions the case of a patient at University of Pennsylvania Hospital when Dr. William Goodell removed a 112 lbs tumor from a 31 year old patient, who weighted 75 lbs after removal from the tumor.
