Fig. 1C. —Borderline serous surface papillary tumors of bilateral ovaries in 26-year-old woman. On T2-weighted axial image (B) (TR/TE, 3,977/99) and sagittal MR images (4,072/99) of right (C) and left (D) ovaries, masses (arrows) are multilobulated and have internal branching patterns (black arrowheads).

The diagnosis of borderline tumor should be considered when an ovarian tumor with an abundance of papillary projections is seen in young patients. Since imaging specificity does not allow confident differentiation of a borderline tumor from a malignant serous ovarian neoplasm, both types of tumor require exploratory laparotomy for surgical and pathologic staging ( , 13 ).

Ovarian serous borderline tumor (SBT) is a low grade epithelial neoplasm of generally younger women with a favorable prognosis when diagnosed at an early stage. Defined, nonobligate precursor to low grade serous carcinoma (LGSC) As a borderline tumor, can give rise to extra-ovarian abdominoperitoneal or lymph node implants. Borderline epithelial tumors are also known as atypical proliferating tumors and used to be called low malignant potential tumors. These tumors look the same as invasive epithelial ovarian cancers when seen on an ultrasound or CT scan. Doctors can't be sure whether a tumor is invasive or borderline until a biopsy sample has been taken (usually during surgery) and checked in a lab.

According to the clinical and pathological features, ovarian serous tumors are divided into benign, borderline, and malignant. Among these, serous borderline tumor (SBT) accounts for 15% 1. Like most epithelial ovarian tumors, borderline papillary tumors are derived from serous or mucinous cell types. These tumors are a subset of ovarian epithelial neoplasms that are associated with extraovarian disease but have an indolent course and a more favorable prognosis than that typical of their malignant counterparts (, 1 –, 4). Borderline ovarian tumors represent a heterogeneous group of noninvasive tumors of uncertain malignant potential with characteristic histology.

Borderline epithelial ovarian tumors, or tumors of low malignant potential, were first described in 1929. 1 Borderline tumors have an excellent prognosis and are common in woman of childbearing age. Surgical excision with total abdominal hysterectomy and bilateral salpingo-oophorectomy has been the primary treatment, with a trend toward fertility conservation in young women.

They tend to develop in an exophytic growth pattern, on the surface of the ovary, without invading the underlying stroma. Papillary projections are characteristic and may be more of a feature with borderline than malignant serous cystadenocarcinoma of the ovary. Thus, although borderline ovarian tumors may appear to be benign masses clinically, their radiologic features require differentiation from early invasive disease [ 3 – 6 ]. Both borderline and stage I tumors are usually multiloculated with significant solid elements.

This article will review the sonographic SEROUS HISTOLOGICAL TYPE is the most common ovarian tumor, accounting for 20% of all ovarian tumors 1. According to the clinical and pathological features, ovarian serous tumors are divided into benign, borderline, and malignant. Among these, serous borderline tumor (SBT) accounts for 15% 1. Like most epithelial ovarian tumors, borderline papillary tumors are derived from serous or mucinous cell types.

Benign mucinous neoplasms include mucinous cystadenoma and mucinous adenofibroma and account for 80% of cases. Borderline tumors (mucinous borderline tumor/atypical proliferative mucinous tumor) are the next most common type, accounting for 16%–17% of cases.

A B S T R A C T. Histologically distinct tumors that coexist in an organ without any histological admixture at their interface are denominated collision tumors. We report 3 cases of colliding mature cystic teratoma with mucinous cystadenoma and a case of mature cystic teratoma colliding with benign Brenner tumor in the ovary. Borderline epithelial tumors are also known as atypical proliferating tumors and used to be called low malignant potential tumors.These tumors look the same as invasive epithelial ovarian cancers when seen on an ultrasound or CT scan. However, the mechanism of serous borderline tumor with micro-invasive carcinoma of ovary metastasizing to breast in early stage still needs to be explored. 4 Conclusions.

The present study aimed to assess the efficacy of MR imaging for differentiating between DEs and SMBTs of the ovary. The creation of the category of borderline/atypical proliferative tumors in the World Health Organization Classification of Ovarian Tumors in 1973 prompted extensive investigation of the clinicopathologic and genetic features of low-grade serous ovarian tumors (borderline tumors/atypical proliferative tumors, noninvasive micropapillary tumors, and invasive low-grade serous carcinomas). 68 year old woman with a benign Brenner tumor arising in an ectopic ovary (Int J Gynecol Pathol 2020 Sep 17 [Epub ahead of print]) Borderline Brenner tumor: 68 year old woman with borderline Brenner tumor (J Ovarian Res 2014;7:101) Malignant Brenner tumor: 2018-03-21 · Endometrioid Borderline Tumor of Ovary is an ovarian tumor with low or borderline malignant potential. It is less common than other types of tumor and the causal factors are unknown Tumors of the ovaries can be benign, borderline or low malignant potential (LMP), or malignant tumors. A comprehensive video on serous borderline ovarian tumors developed by the students of the Univ.

Coronal, T2-weighted images demonstrate a right cystic adnexal lesion (black arrows).(a) The left ovary (white arrow) contains a prominent follicle in its superior aspect demonstrating an intracystic papillary projection (arrowhead) surrounded by apparently normal ovarian tissue. Tumors of low malignant potential (i.e., borderline tumors) account for 15% of all epithelial ovarian cancers. Nearly 75% of these tumors are stage I at the time of diagnosis. These tumors must be recognized because their prognosis and treatment is clearly different from the frankly malignant invasive carcinomas. 2020-07-01 · We present here a case of bilateral complex ovarian mass in a 68-year-old woman, which was equivocal for malignancy on radiology, per operative gross examination as well as on frozen section evaluation.
