Ovary with Mucinous cystadenoma
Clinical story
33 years old female with a cystic mass in the right ovary. A right-sided oophorectomy was performed.
Comments
Gross examination shows a multilocular cyst with mucinous content and remains
of the fallopian tube. Section through the cyst wall reveals a multilocular tumor with cysts lined by mucinous, columnar epithelium. The epithelium is regular,
with no excrescences, and polarized cells with small nuclei. A cross-section of
the fallopian tube is also present. Ovarian stroma may be recognized by scattered primordial follicles.
Learning goals
To recognize mucinous cystadenoma of the ovary. Additionally, to understand the division of epithelial tumors of the ovary by histological type and the degree of malignancy.
