Classification of ovarian cancer

There are many methods for classifying ovarian cancer, and the classification based on tissue occurrence has clinical practical significance.

(I) Ovarian malignant tumors originating from the embryonic epithelium (paramesonephric coelomic epithelium)

Such as serous adenocarcinoma, mucinous adenocarcinoma, endometrioid adenocarcinoma, mixed serous mucinous cystadenocarcinoma, fibroadenocarcinoma, malignant Brenner's tumor, paramesonephric clear cell carcinoma, undifferentiated (anaplastic) carcinoma, etc. These tumors sometimes have a degenerative effect.

2. Ovarian malignancies of germ cell origin

Such as teratocarcinoma, primary choriocarcinoma, dysgerminoma, etc., can sometimes secrete hormones.

3. Ovarian malignant tumors of undifferentiated mesenchymal origin

Such as benign tumors, sarcomas of the same name, malignant mixed mesodermal tumors, and carcinosarcoma.

4. Ovarian malignant tumors of sexually differentiated mesenchymal origin

Because they have the ability to produce their own hormones, they are also called functional tumors and are all potential malignant tumors.

1. Feminizing mesenchymal tumors include ① granulosa cell tumors; ② theca cell tumors; ② granulosa-follicular cell tumors. 2. Masculinizing mesenchymal tumors include ① testicular cell tumors; ② hilar cell tumors. 3. Bisexualization: bisexual gynecomastia.

5. Ovarian malignant tumors arising from the mesonephric tract

Such as malignant mesonephroma.

6. Ovarian malignancies arising from ectopic tissues in the ovary

Malignant adrenal cell remnant tumor.
