Microinvasion may be represented by a single focus or multiple

serous borderline tumors and serous borderline tumors with non-invasive micropapillary pattern [1]. Eclipse E600 microscopeA particular aspect of typical or micropapillary serous borderline tumors is stromal microinvasion. The concept of microinvasion in serous borderline tumors has been recognized for nearly 50 years [2,3].

Borderline tumor Last updated July 29, 2020. A borderline tumor, sometimes called low malignant potential (LMP) tumor, is a distinct but yet heterogeneous group of tumors defined by their histopathology as atypical epithelial proliferation without stromal invasion. [1] Keywords Borderline tumours, conservative treatment, fertility, ovary, recurrence, stromal microinvasion. Please cite this paper as: Laurent I, Uzan C, Gouy S, Pautier P, Duvillard P, Morice P. Results after conservative treatment of serous borderline tumours of the ovary with stromal microinvasion but without micropapillary pattern. Borderline ovarian tumors account for approximately 15% of all epithelial ovarian tumors. In the early 1970s, borderline tumors were categorized as either serous or mucinous with overall survival rates of 75–90%.

Grade 1 serous carcinoma was less common than SBT and had a more unfavorable prognosis. The qualitative histologic similarity between microinvasion, invasive implants, recurrences and grade 1 serous carcinoma suggests that microinvasion represents early invasion and is not just another histologic pattern of SBT. These data suggest that serous borderline tumors with microinvasion have a prognosis similar to that of the usual serous borderline tumor, and that conservation of the contralateral ovary and uterus may be acceptable therapy in young women who wish to preserve their fertility. 2007-07-01 · Microinvasion was easily identified in SBT by a change in architecture (Fig. 4, Fig. 5). There was a higher epithelial to stromal ratio than the adjacent serous borderline tumor.

Am J Surg Pathol. 2002 ; 26 : 1111 –28. 5. Serous borderline tumor of the ovary initially was described in 1929 by Taylor. 1 Current information suggests that women with Stage I serous borderline tumors have an excellent prognosis, with a disease free survival rate approaching 100%.

F. Leake et al. 1991). Metastasis to the lymph nodes has rarely been reported (M. D. Chamberlin et al., 2001; M. B. … 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. Rarely, endometrioid, clear-cell, or transitional cell (Brenner) borderline tumors are found.

1991).

Two of 13 (15%, 95% CI 8.7, 21.3) patients with microinvasion died of recurrent invasive cancer, whereas only 1 out of 113 patients without microinvasion died of recurrent borderline tumor (OR 20 The nomenclature and diagnostic criteria of mucinous borderline ovarian tumors (M-BOTs) are controversial. We report a case of M-BOT with microinvasion that relapsed, with an unfavorable outcome. A 40-year-old Japanese female underwent emergent laparotomy (left salpingo-oophorectomy) for a ruptured ovarian cystic tumor.

2021-03-02 · Microinvasion: About 10% of SBT cases show small foci ( 5mm) of microinvasion consisting of clusters of cells in the stroma just beneath the surface component. These tumor cells have abundant eosinophilic cytoplasm like the surface papillae. They don't express ER/PR, have low Ki-67 labeling index and don't worsen the prognosis significantly.

2, pp. 278–286, 1996. Figure 26.10 Mucinous endocervical-like borderline tumor with IEC and microinvasion. The lining epithelium shows cell stratification, cribriform pattern, and marked nuclear atypia. A nest of invasive cells is seen at the lower left corner. was a borderline ovarian tumor with stromal microinvasion and hemangiomatous mural nodules.

1 Mar 2012 In 12 series of serous borderline ovarian tumours with microinvasion (n=133), 20 patients had recurrence (15%), including 35% (seven of 20)

21 Although often asymptomatic, the tumor may sometimes present with abdominal enlargement and pain due to rupture or torsion. . Approximately 70% are confined to one or both In one report, 44 "mucinous borderline tumor with microinvasion" is used for those tumors lacking intraepithelial carcinoma, and "mucinous borderline tumor with microinvasive carcinoma" is used for those containing intraepithelial carcinoma.

In one case, the microinvasion was of eosinophil type, and in the other case it had a glandular and micropapillary pattern associated with noninvasive peritoneal implants. The histological characteristics of stromal microinvasion in serous borderline tumors have Objective The aims of this study were to evaluate the rate of recurrences in borderline ovarian tumors (BOTs) with microinvasion and to evaluate the possibility to enlarge fertility-sparing surgery in … Typically, the borderline tumor was a large, multilocular neoplasm that had papillary infoldings and two to three layers of atypical epithelial cells, but no invasion of the stroma. 2021-04-06 Borderline tumors with intraepithelial carcinoma and/or microinvasion provide evidence that these tumors form a morphologic spectrum with individual types representing steps in the sequence of mucinous carcinogenesis in the ovary . 2017-10-25 Endocervical-like mucinous borderline ovarian tumors (E-LMBOTs) or APE-LMOTs with microinvasion are defined as tumors with one or more foci of single cells, irregular glands, or small nests of confluent mucinous cells infiltrating the underlying stroma. Borderline is usually treated with surgery and followup.
