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.
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
Rarely, endometrioid, clear-cell, or transitional cell (Brenner) borderline tumors are found. 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.
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. SINQ 20170043 is a similar question about an ovarian mucinous borderline tumor with microinvasion, but the answer seems to be specifically referencing mucinous tumors only. It is unclear if that SINQ could be applied to this case. In addition, we were not sure how to interpret the nodal involvement. Rationale: Breast metastasis from serous borderline tumor with micro-invasive carcinoma of ovary is a very rare condition.
Microinvasion was observed in 5.3% and a micropapillary pattern in 12.6%. Borderline tumors of the ovary (BOTs) represent a specific group of epithelial

Low malignant potential/borderline ovarian tumors are defined by the pathology of the primary tumor in the ovary, and microinvasion there, or invasion in implants does not change that diagnosis. 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.
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.

Comments: Borderline clear cell adenofibroma with a 2mm focus of microinvasion in a 10 cm tumor. The remainder of the tumor was composed entirely of benign areas. Clear cytoplasm and cytologic atypia are evident in the small nests.The larger dilated glands are lined by flattened epithelium lacking atypia. women (6.1%) had mixed borderline tumors, includ-ing 1 with microinvasion.

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.
