One hundred eighty, six cases of ovarian common "epithelial" tumor including 28
endometriosis were reviewed, from the pathology file of the department of pathology of
the National Medical Center during a period of 8 years and 6 months from January 1976
to June 1984.
The study consisted of 14 cases(77.4%) of benign tumor including 28cases of ovarian
endometriosis, and 21 cases(11.3%) of borderline malignancy and 21 cases(11.3%) of
invasive malignant tumors.
Among benign common "epithelial" tumors, mucinous cystadenoma(69 cases) was the
most frequent tumor, followed by serous cystadenoma(42 cases) and Brenner tumor(5
cases).
Of borderline tumor, borderline mucinous tumor (18 cases) was more frequent than
serous tumor(3 cases).
Serous cystadenocarcinoma(9 cases) was the most frequent malignant tumor, followed
by mucinous cystadenocarcinoma(6 cases), endometrioid carcinoma(3 cases) and
undifferentiated carcinoma(3 cases).
Most ovarian common "epithelial" tumors were prevalent during the reproductive age,
but malignant tumors were more prevalent after the age of 40.
Although right sloe was more frequently found(85 vs. 67) there is no significant site
Predilection.
Bilaterality was the most common in undifferentiated carcinoma(66.7%), followed by
serous cystadenocarcinoma(44.4%) and Brenner tumor(40%).
The size of tumor tended to be larger in malignant tumor than benign. Mucinous
tumor were usually larger than serous tumor.
There were 7 intrauterine and 1 ectopic tubal pregnancy which were associated with
ovarian common "epithelial" tumors. Three cases of tumors were excised during
Cesarian section.
In summary these findings are comparable to other reports in Korea and English
literatures. Histologic analysis of borderline and malignant epithelial tumor was done to
emphasize their biologic behavior. Further study is required to compare their histological
grading and clinical staging with their survival rate.
