• The five main types of ovarian carcinoma are essentially distinct diseases. Ovarian borderline tumors have also been referred to as “tumors of low malignant potential” or “atypical proliferative tumors”; however “borderline tumor” is the preferred terminology. Borderline tumors exhibit epithelial proliferation and cytologic atypia, beyond that acceptable for a benign neoplasm, but do not exhibit the destructive growth seen in carcinomas. Borderline tumors account for 14 to 15 percent of all primary ovarian neoplasms . Borderline tumors occur in a variety of histologies, as in epithelial ovarian carcinoma . The majority of cases are serous or mucinous.

Borderline tumors occur in a variety of histologies, as in epithelial ovarian carcinoma [ 5,6 ]. The majority of cases are serous or mucinous. Rarely, endometrioid, clear-cell, or transitional cell (Brenner) borderline tumors are found. Compared with benign tumors, borderline serous tumors have more exuberant and finer papillary projections within the cyst cavity. Similar projections also may occur on the external surface of the tumor. Small tumorlets with similar features may be found elsewhere on the internal lining of the pelvic and abdominal cavities in up to 40% of patients. 2021-03-02 A comprehensive video on serous borderline ovarian tumors developed by the students of the Univ.

Serous borderline tumors (Atypical proliferating serous tumors) of the ovary are non-invasive tumors that show greater epithelial proliferation and cytologic atypia and a more complex papillary architecture than benign serous tumors. They make up about 15% of all ovarian serous tumors.

They make up about 15% of all ovarian serous tumors. About … 2021-03-02 2021-03-02 2020-06-12 Thirty-four tumors (64%) were classified as atypical proliferative (borderline) tumors based on the absence of stromal invasion and the absence of micropapillary architecture measuring >5 mm. Five tumors (9%) qualified as intraepithelial carcinoma based on the presence of marked cytologic atypia or a complex cribriform growth pattern involving the epithelium covering the surface of papillae or lining … Borderline ovarian tumors show epithelial proliferation higher than that seen in their benign counterparts and variable nuclear atypia; however, in contrast to carcinomas, there is no destructive stromal invasion, and their prognosis is much better. Ovarian borderline tumors have also been referred to as “tumors of low malignant potential” or “atypical proliferative tumors”; however “borderline tumor” is the preferred terminology. Borderline tumors exhibit epithelial proliferation and cytologic atypia, beyond that acceptable for a benign neoplasm, but do not exhibit the destructive growth seen in carcinomas.

These tumors must be recognized because their prognosis and treatment is clearly different from the frankly malignant invasive carcinomas. 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 of borderline malignancy of mullerian type," or "atypical proliferative seromucinous tumors." stitute of Pathology (AFIP). All ovarian tumors orig-inally diagnosed as clear cell AF, APT/borderline tumor /tumor of low malignant potential, and clear cell CA from 1971 to 2004 were retrieved from the files of the AFIP in Washington, D.C.

Fibroblastic mesenchymal tumors show a spectrum of biological behavior, from benign to fully malignant. We report our experience of two decades with a distinctive, previously undescribed low-grade fibroblastic tumor of the superficial soft tissues. Eighteen cases were identified within our consultat … Brenner tumors arise from ovarian epithelium, accounting for approximately 5% of benign ovarian epithelial tumors.
