Ovarian cancer pathological changes

Ovarian tumor tissue morphology over the complexity of any organ, it is because: ① ovarian organizational structure with the full development potential of multipotent; ② ovarian occurred in the embryonic period and is very close to the urinary system, part of the kidney can enter the labyrinth ovarian; ③ ovary from embryonic germ ridge, gender identity, after the division. The classification of ovarian tumors many ways, the organization adopted in this chapter is based on a clinical and practical significance of the classification.
(1) embryonic epithelial (deputy in renal epithelial body cavity) as the source of serous ovarian cancer adenocarcinoma, mucinous carcinoma, endometrial adenocarcinoma, mixed serous mucinous cystic carcinoma, adenocarcinoma fiber, vicious tumor, the Deputy of renal cell carcinoma, undifferentiated (anaplastic) cancer, and so on, these tumors sometimes luteinized role.
(B) sources of embryonic cells malignant tumors such as ovarian cancer teratogenic, primary choriocarcinoma cell carcinoma, tumor clones, can sometimes hormone secretion.
(C) of undifferentiated mesenchymal origin such as benign ovarian cancer tumor 1 ~ 6 namesake sarcoma, malignant mixed tumor of the mesoderm, carcinosarcoma.
(D) differentiation of mesenchymal origin have ovarian cancer because of autologous hormone function, also known as the functional tumors are malignant potential.
1. Feminization Mesenchymoma: ① granulosa cell tumor; ② theca cell tumor; ② tablets layer - follicular cell tumors.
2. Masculine Mesenchymoma: ① with testicular tumor; ② doors cell tumor.
3. Gender; gender blastoma.
(5) Since the occurrence of renal anomalies in malignant ovarian tumor as malignant kidney tumor.
(6) Since the occurrence of ovarian ectopic organizations within the ovarian cancer cell anomalies malignant adrenal tumor.
