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 ...
Endometrioma can potentially lead to premature ovarian failure, decreased ovarian function, or problems with ovulation. [4] Studies have also found that endometriomas occur two times more frequently in the left ovary (67%) than in the right one (33%), possibly due to the presence of the sigmoid colon on the left side.
Ovarian cysts may be classified according to whether they are a variant of the normal menstrual cycle, referred to as a functional or follicular cyst. [6] Ovarian cysts are considered large when they are over 5 cm and giant when they are over 15 cm. In children, ovarian cysts reaching above the level of the umbilicus are considered giant.
It is common for many women to develop a cyst in their lifetime. [4] At times, these can go unnoticed without pain or visible symptoms. A cyst may develop in either of the ovaries that are responsible for producing hormones and carrying eggs. Ovarian cysts can be of various types, such as dermoid cysts, endometrioma cysts, and the functional cyst.
Dysgerminoma accounts for less than 1% of ovarian tumors overall. Dysgerminoma usually occurs in adolescence and early adult life; about 5% occur in pre-pubertal children. Dysgerminoma is extremely rare after age 50. Dysgerminoma occurs in both ovaries in 10% of patients and, in a further 10%, there is microscopic tumor in the other ovary.
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.
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.
10-year survival rates for mucinous tumors is excellent in the absence of invasion. In the case of borderline tumors confined to the ovary and malignant tumors without invasion, the survival rates are 90% or greater. In invasive mucinous cystadenocarcinomas, the survival is approximately 30%. Survival in metastasis is between 12 and 30 months. [5]
