The recent 2014 World Health Organization (WHO) Classification of Tumours of the Female Reproductive Organs introduced a new category of ovarian neoplasm designated "seromucinous tumours". The recognition of this distinctive group of tumors…

Since our proposal of a dualistic model of epithelial ovarian carcinogenesis more than a decade ago, a large number of molecular and histopathologic studies were published that have provided important insights into the origin and molecular …

Nongastrointestinal-type mucinous borderline tumors have been described as displaying endocervical and serous differentiation and hence have been termed "endocervical-type" mucinous borderline tumors, "mixed-epithelial papillary cystadenoma…

The cell of origin of ovarian cancer has been long debated. The current paradigm is that epithelial ovarian cancer (EOC) arises from the ovarian surface epithelium (OSE). OSE is composed of flat, nondescript cells more closely resembling th…

Recent morphologic, immunohistochemical, and molecular genetic studies have led to the development of a new paradigm for the pathogenesis and origin of epithelial ovarian cancer based on a dualistic model of carcinogenesis that divides epit…

In contrast to the controversy regarding the terminology and behavior of ovarian noninvasive low-grade serous tumors [atypical proliferative serous tumor (APST) and serous borderline tumor], little attention has been directed to their origi…

Ovarian cancer is the most lethal gynecologic malignancy. Efforts at early detection and new therapeutic approaches to reduce mortality have been largely unsuccessful, because the origin and pathogenesis of epithelial ovarian cancer are poo…

Ovarian clear cell carcinomas (CCC) typically present as large adnexal, stage I tumors and are generally considered highly malignant. They are frequently associated with endometriosis and, less often with clear cell adenofibromas. We hypoth…

The distinction of involvement of adenomyosis by endometrial carcinoma from endometrial carcinoma invading the myometrium can at times be difficult. This distinction, however, is important from the standpoint of staging, treatment, and prog…

We have observed luminal and mucosal calcifications frequently surrounded by a mantle of bland epithelium in the fallopian tubes ("salpingoliths") of women with serous tumors of the ovaries. These lesions resemble noninvasive peritoneal "im…

Perforin is a marker of functionally active cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. We examined perforin expression in endometrium throughout the menstrual cycle. In addition, perforin expression was studied in endomet…

Two hundred and thirty cases of primary ovarian carcinoma derived from the surface epithelium of the ovary were reviewed over a 30-year period ending in 1960. Of these, 37 (16%) were classified as endometrioid and 12 (5%) as clear cell carc…
