Borderline tumors fall under ovarian epithelial tumors. 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.

Large mass with numerous loculations but no solid component or papillary projections. This appearance is typical for a mucinous borderline tumor - although not pathognomonic and has overlap with both mucinous cystadenomas, as well as malignant lesions e.g. low grade mucinous adenocarcinoma.

Read "Borderline Brenner tumor of the ovary: MRI findings, Abdominal Radiology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Borderline tumors of the ovary (also called tumors of low malignant potential) are a heterogeneous group of lesions defined histologically by atypical epithelial proliferation without stromal invasion . The behavior of these tumors is distinct from low-grade ovarian carcinoma, and they are considered a distinct clinical entity.

Borderline tumors (mucinous borderline tumor/atypical proliferative mucinous tumor) are the next most common type, accounting for 16%–17% of cases. The remaining 3%–4% of primary tumors are ovarian mucinous carcinomas (1,2). Metastatic mucinous tumors, particularly those of gastrointestinal Nonserous, nonmucinous borderline ovarian tumors do not show characteristic imaging features and may resemble other borderline ovarian tumors as well as early-stage ovarian carcinomas . The miscellaneous borderline ovarian tumors chart a benign course after tumor removal with exceptionally rare recurrences or metastasis.

Ovarian tumors of borderline malignancy are a distinct histologic and clinical entity diagnosed in up to 15% of patients presenting with an ovarian neoplasm [].Compared with frankly malignant tumors, borderline tumors have a much better prognosis and, because they are noninvasive, may be treated less radically than invasive ovarian cancer [1, 2]. Case Discussion. Discussion: Large mass with numerous loculations but no solid component or papillary projections. This appearance is typical for a mucinous borderline tumor - although not pathognomonic and has overlap with both mucinous cystadenomas, as well as malignant lesions e.g. low grade mucinous adenocarcinoma.

Borderline Tumors of the Ovary: CT and MRI Features and Tumor Markers in Differentiation from Stage I Disease American Journal of Roentgenology, Vol. 184, No. 3 … Purpose: Decidualized endometriomas (DEs) and seromucinous borderline tumors (SMBTs) exhibit similar MR findings including markedly hyperintense mural nodules within endometriotic cysts on T2-weighted images. The present study aimed to assess the efficacy of MR imaging for differentiating between DEs and SMBTs of the ovary. Rationale: Breast metastasis from serous borderline tumor with micro-invasive carcinoma of ovary is a very rare condition.

Herein, we report magnetic resonance imaging (MRI) findings of a mucinous borderline tumor of the ovary, which we observed as a mainly solid tumor with large solid components in the lower pelvic cavity. The appearance of ovarian epithelial tumors on imaging is often complex. Cystic to solid appearing masses may be observed, and they often resemble epithelial carcinoma.

2007-09-05 Ovarian serous tumors are classified as benign (60%), borderline (15%), or malignant (25%) according to their biological nature. 1, 2 With a low malignant potential, borderline tumors histologically demonstrate mitotic activity and nuclear atypia that are intermediate to those of their clearly benign and overtly malignant counterparts, but without stromal invasion. 2, 3 The clinical importance Masaya Kawaguchi, Hiroki Kato, Yuichiro Hatano, Hiroyuki Tomita, Akira Hara, Natsuko Suzui, Tatsuhiko Miyazaki, Tatsuro Furui, Ken-ichirou Morishige, Masayuki Matsuo, MR imaging findings of low-grade serous carcinoma of the ovary: comparison with serous borderline tumor, Japanese Journal of Radiology, 10.1007/s11604-020-00960-2, (2020). Borderline ovarian tumors are relatively uncommon with an incidence of 1.5–2.5 per 100,000 people per year.

Ovarian serous tumors are classified as benign (60%), borderline (15%), or malignant (25%) according to their biological nature. 1, 2 With a low malignant potential, borderline tumors histologically demonstrate mitotic activity and nuclear atypia that are intermediate to those of their clearly benign and overtly malignant counterparts, but without stromal invasion. 2, 3 The clinical importance of borderline tumors is that they have a better prognosis than that of their malignant counterparts
