Ovarian cancer is a cancerous tumor of an ovary. [10] It may originate from the ovary itself or more commonly from communicating nearby structures such as fallopian tubes or the inner lining of the abdomen. [3] [11] The ovary is made up of three different cell types including epithelial cells, germ cells, and stromal cells. [12]
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 clear-cell carcinoma, or clear-cell carcinoma of the ovary, also called ovarian clear-cell adenocarcinoma, is one of several subtypes of ovarian carcinoma – a subtype of epithelial ovarian cancer, in contrast to non-epithelial cancers. According to research, most ovarian cancers start at the epithelial layer which is the lining of the ...
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.
Brenner tumours are an uncommon subtype of the surface epithelial-stromal tumour group of ovarian neoplasms. The majority are benign, but some can be malignant. [1] They are most frequently found incidentally on pelvic examination or at laparotomy. [2] Brenner tumours very rarely can occur in other locations, including the testes. [3]
The appearance can look similar to colonic cancer. Clear stromal invasion is used to differentiate borderline tumors from malignant tumors. Pseudomyxoma peritonei may present as a result of an ovarian mucinous tumor, however this is a rare cause of this condition, which is a rare condition. A more common cause of pseudomyxoma peritonei is a ...
Papillary serous cystadenocarcinomas are the most common form of malignant ovarian cancer making up 26 percent of ovarian tumours in women aged over 20 in the United States. [ 1 ] As with most ovarian tumours, due to the lack of early signs of disease these tumours can be large when discovered and have often metastasized , often by spreading ...
Gynecologic cancer is a type of cancer that affects the female reproductive system, including ovarian cancer, uterine cancer, vaginal cancer, cervical cancer, and vulvar cancer. Gynecological cancers comprise 10-15% of women's cancers, mainly affecting women past reproductive age but posing threats to fertility for younger patients. [ 1 ]
