Figure 4

Resected specimens and histopathological findings. (a) Right adnexa (white arrow), left adnexa (yellow arrow), and the nodule of the right round ligament (blue arrow) were resected laparoscopically. (b, c) Histopathological examination shows that the ovarian tumor is a seromucinous borderline tumor. Papillary structure with serous, endocervical-type mucinous, and ciliated cells with mild nuclear atypia was found in the nodule of the cyst. (d) Adenocarcinoma tissues can be observed in the right round ligament and mesenteric nodules. Adenocarcinoma tissues are (e) GATA3 positive, (f) CK7 positive, (g) CK20 negative, (h) ER negative, and (i) PgR weakly positive. GATA3: GATA-binding protein; CK: cytokeratin; ER: estrogen receptor; PgR: progesterone receptor.
