Similarly, the presence of potentially precancerous processes in the ovary such as endometriosis or a preexisting benign or borderline tumor
of similar histological type suggests de novo development of the cancer also in the ovary.
(10) However, a series of reports have documented that KS showed a greater geographic variation in incidence than almost any other borderline tumor
. Earlier reports have documented that it was commonly seen in parts of Sub-Saharan Africa, such as Uganda and Zaire, constituting 9% of all cancer in men.
However, in the study conducted by Emmanuel et al., activating NRAS mutations were found in 5 out of 58 (9%) invasive serous epithelial ovarian carcinomas coexisting with a serous borderline tumor
and in none of the 53 isolated SBOTs.
This variant may also contain cystic areas with edematous papillae and micropapillae resembling serous borderline tumor
. The retiform variant is exceptional among sex-cord tumors because it has no definitive testicular counterpart and likely arises from a more primitive cell type [7, 8, 11].
Coexistence of three benign and a borderline tumor
in the ovaries of 52-year-old women.
The final histologic examination objectified intracystic intestinal type ovarian mucinous borderline tumor
which corresponded to a Demons' pseudosyndrome.
Fortunately, my pathology came back better than expected and I was diagnosed with a borderline tumor
, which is a low-malignant form of the disease.
In January 1994, at the age of 38, I was diagnosed with what the doctor called a "small focus of clear cell carcinoma" within a "borderline tumor
" in my ovary.
McCluggage, "Low-grade ovarian serous neoplasms (low-grade serous carcinoma and serous borderline tumor
) associated with high-grade serous carcinoma or undifferentiated carcinoma: report of a series of cases of an unusual phenomenon," The American Journal of Surgical Pathology, vol.
(7) HL can also mimic ovarian malignancies like mucinous borderline tumor
of intestinal type; however, they are differentiated by the fact that they have smaller thin-walled cysts and not as much solid component as seen in HL.
Prognostic significance for histologic grading as well as lymphovascular invasion (LVI) is limited to node-negative breast cancers, with borderline tumor
