Pathology - Ovarian benign tumors
Cystic teratoma in maturity Benign germ cell ovarian tumors, sometimes referred to as "dermoid cysts," are most common in young women aged 20 to 29. • Larger tumors may cause pelvic pain, but many are asymptomatic and found by accident. Torsion or rupture, which results in an acute abdomen, is the most dangerous consequence. • The tumor appears cystic from a macroscopic perspective and contains a soft, greasy yellow substance. Teeth, bone, cartilage, and hair may be apparent. • According to histology, the tumor is made up of mature adult-type tissues of almost any kind, such as cartilage, smooth muscle, fat, skin, brain, respiratory, and gastrointestinal tissue.Although they are far less common, the majority of other germ cell ovarian tumors (such as dysgerminoma and immature teratoma) exhibit malignant behavior.
Cystadenoma serous -Benign epithelial ovarian tumors typically affect premenopausal women. They can be discovered by chance when a pelvic mass or an acute abdomen from torsion is present. They can be unilocular or multilocular in appearance. Histologically, the cysts are lined by a single layer of bland columnar cells, which may be ciliated or non-ciliated. The cysts contain clear fluid and have a thin wall with a smooth lining.
Cystomatous mucinous tumor • Premenopausal women typically develop benign epithelial ovarian tumors. • It may be discovered by chance when there are signs of a pelvic mass or an acute abdomen brought on by torsion. • On a macroscopic level, the tumor is often unilateral and measures 10 cm on average, though there have been cases of enormous tumors. One or more cysts filled with viscous mucoid material make up the tumor. • A single layer of bland columnar cells, either intestinal or endocervical in origin, lines the cysts histologically.
Ovarian Fibroma
Benign sex-cord stromal ovarian tumors, which are made of collagen and fibrocytes, can occur in a variety of age groups, although the majority are found in women over 50. They are frequently found by accident and are little. Ascites and stomach pain may result from a large tumor. • From a macroscopic perspective, the tumor has a solid white sliced surface. • According to histology, the tumor is made up of bland spindled cells that are expanding within a collagenous stroma.
Ovarian tumors that are borderline epithelial
A class of epithelial tumors known as borderline epithelial ovarian tumors tends to behave indolently yet shows more marked proliferation than benign epithelial tumors. Serous (borderline serous) tumors make up the great bulk of borderline epithelial tumors. At the macroscopic level, they are enormous, often bilateral, cystic tumors that are typically multifocal. Numerous papillary excrescences protrude from the cysts' surface. The tumors exhibit low-grade nuclear atypia and are histologically formed of complicated branching papillae covered by proliferating columnar epithelial cells. The existence of tiny tumor "implants" in the peritoneum or omentum in around 15% to 30% of cases is an odd characteristic of borderline serous tumors. These implants can be classified as either invasive or non-invasive histologically. The majority are non-invasive, and the prognosis for these patients is typically favorable. Although invasive implants are extremely uncommon, they are typically linked to a poor prognosis
