Serous tubal intraepithelial carcinoma: Emerging trend in ovarian neoplasm: A must know for a pathologist

Among all gynecological malignancies, ovarian cancer is associated with the highest rate of mortality. Most ovarian carcinomas have been suggested to originate from the ovarian surface epithelium or postovulatory inclusion cysts formed after follicular rupture and repair. Over the past decade, a new model has emerged to explain the origin of epithelial tumors of the ovary and the fallopian tube now appears to play a central role; however, there is now compelling evidence that many epithelial pelvic cancers, especially high-grade serous carcinomas of the ovary/peritoneum, begin in the mucosa of the fallopian tube as serous tubal intraepithelial carcinoma.
