Later symptoms of ovarian cancer are due to the growing mass causing pain by pressing on other abdominopelvic organs or from metastases. [26] [30] [31] Because of the anatomic location of the ovaries deep in the pelvis, most masses are large and advanced at the time of diagnosis. [14] The growing mass may cause pain if ovarian torsion develops ...
Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
High-grade serous carcinoma (HGSC) is a type of tumour that arises from the serous epithelial layer in the abdominopelvic cavity and is mainly found in the ovary.HGSCs make up the majority of ovarian cancer cases [1] and have the lowest survival rates. [2]
Ovarian squamous cell carcinoma (oSCC) or squamous ovarian carcinoma (SOC) is a rare tumor that accounts for 1% of ovarian cancers. [1] Included in the World Health Organization 's classification of ovarian cancer, [ 2 ] it mainly affects women above 45 years of age.
The mass effect of ovarian tumors is also a common cause of torsion. Torsion of the ovary usually occurs with torsion of the fallopian tube as well on their shared vascular pedicle around the broad ligament, although in rare cases the ovary rotates around the mesovarium or the fallopian tube rotates around the mesosalpinx. In 80%, torsion ...
They are estrogen-secreting tumours and present as large, complex, ovarian masses. These tumours are part of the sex cord–gonadal stromal tumour or non-epithelial group of tumours. Although granulosa cells normally occur only in the ovary, granulosa cell tumours occur in both ovaries and testicles (see ovarian cancer and testicular cancer ...
Krukenberg tumors often come to the attention when they cause abdominal or pelvic pain, bloating, ascites, or pain during sexual intercourse.Krukenberg tumors can occasionally provoke a reaction of the ovarian stroma which leads to hormone production, that results in vaginal bleeding, a change in menstrual habits, or hirsutism, [3] or occasionally virilization [4] as a main symptom.
Ovarian germ cell tumors (OGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad, which accounts for about 2.6% of all ovarian malignancies. [1] There are four main types of OGCTs, namely dysgerminomas , yolk sac tumor , teratoma , and choriocarcinoma .
