Differentiation from primary breast cancer and Mucinous tumors account for 10–15% of all primary ovarian tumors. 1 Approximately 80% are benign and the remainder are borderline tumors, noninvasive carcinomas, and invasive carcinomas. 1 Although they generally occur in older women (mean ages 51–54 years), mucinous borderline tumors and carcinomas are more common in the first two decades than their serous counterparts. 2 Mucinous tumors 2019-03-01 Serous borderline tumors of the ovary: a long-term follow-up study of 137 cases, including 18 with a micropapillary pattern and 20 with microinvasion. Am J Surg Pathol. 2002 ; 26 : 1111 –28. 5.

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. The microinvasive tumors were composed of one or more single cells, small nests and small papillae in desmoplastic stroma. Some studies conclude that serous borderline tumors with microinvasion have a similar prognosis to that of the normal serous borderline tumor [2, 12,19], and conserving the contralateral ovary and typical serous borderline tumors with stromal microinvasion (14.2%). 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.

A 40-year-old Japanese female underwent emergent laparotomy (left salpingo-oophorectomy) for a ruptured ovarian cystic tumor. The pathological diagnosis was M-BOT of the left ovary with microinvasion Some studies conclude that serous borderline tumors with microinvasion have a similar prognosis to that of the normal serous borderline tumor [2, 12, 19], and conserving the contralateral ovary Borderline ovarian tumor. Borderline ovarian tumours differ from epithelial ovarian cancer by their low incidence, frequent association with infertility, low association with mutations in BCRA genes, different percentages of the most common histological types, early stage diagnosis, and high survival rate, even when associated with peritoneal involvement. Microinvasion is reported in up to nine per cent of mucinous borderline tumours of intestinal-type.1 Invasive foci may consist of single cells, small clusters, glands or foci of confluent or cribriform growth within the stroma (see Figure 6).

Some studies conclude that serous borderline tumors with microinvasion have a similar prognosis to that of the normal serous borderline tumor [2, 12,19], and conserving the contralateral ovary and Nayar et al. 13 described microinvasion in mucinous borderline tumors that had foci of invasion of < 2 mm and believed that those tumors had a prognosis similar to usual mucinous borderline tumors without microinvasion. However, too few cases of mucinous tumors with microinvasion have been reported to determine their significance. 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 [ 26 ]. 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. 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.

I would ask the doctor to explain exactly what is meant by microinvasion, what type of follow up he suggests, if he has had experience with other borderline patients and how they have progressed. 2011-12-17 Mucinous tumors of the ovary are a continuing source of controversy in the field of gynecologic pathology. We examined a series of 171 intestinal-type mucinous tumors of low malignant potential (“borderline” or “atypical proliferative” tumors) to clarify the clinical significance of intraepithelial carcinoma (IECA) and microinvasion (area ≤10 mm 2). 2012-09-01 Borderline ovarian tumors are histologically characterized as epithelial tumors with a stratified growth pattern but without destructive stromal invasion. Serous and mucinous neoplasms constitute the majority of borderline tumors and occur mostly in women of reproductive age [ 1 ].

However, for women with serous borderline tumors with peritoneal Borderline tumour (Required or recommended) Reason/Evidentiary Support Histologic Type (Required) Terminology for ovarian borderline tumours has evolved over several years.1,2 The preferred terminology is borderline tumour, for example serous or mucinous borderline … As indicated above, survival of patients who had tumors that showed microinvasion is 100%, and survival of patients with lymph node involvement is 98%. 7 In six prospective, randomized trials including approximately 373 patients with serous borderline tumors followed for a mean of 6.7 years, the survival was 100%. 7 That the survival for stage I is virtually 100% was a general point of Stromal microinvasion has been recently described in ovarian mucinous borderline tumors (MBTs), leading to proposals for new classifications, including a category of MBTs with stromal microinvasion. This study was conducted to test the validity of this belief. borderline tumor (SMBT) is thus a synonym for MEBT-M, MMBT, and EMBT. invasion of < 5 mm in greatest dimension is deﬁned as microinvasion, regardless of number of foci; tumors with microinvasion are considered SMBT (“SMBT with microinvasion”).

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. Hums PATROL 21:397-403. 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 this group of patients.

Restaging Operations The epidemiologic characteristics of women who un-derwent restaging after incomplete initial staging (n Borderline Tumors Summary –he term “seromucinous” is synonymous T with the endocervical/Mullerian type of mucinous borderline tumor. – Distinctive and differ from the GI type; in many ways are similar to serous borderline tumors. – Data are limited but overwhelming benign behavior observed so far Clinical Features. Serous borderline tumors (SBTs) account for one-fourth to one-third of the non-benign serous tumors. 26,27 They are most common in the fourth and fifth decades, with an average patient age of 42 years. 21 Although often asymptomatic, the tumor may sometimes present with abdominal enlargement and pain due to rupture or torsion. .
