In younger women, they are more common, thus in patients under the age of 21, 60% of ovarian tumors are of the germ-cell type, and up to one-third are malignant. In males, GCTs of the testis occur typically after puberty and are malignant ( testicular cancer ).
Bloating, abdominal distention, ascites, dyspareunia. 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 ...
Germ-cell tumors tend to occur in young women (20s–30s) and girls, making up 70% of the ovarian cancer seen in that age group. [33] Germ-cell tumors can include dysgerminomas, teratomas, yolk sac tumors/endodermal sinus tumors, and choriocarcinomas, when they arise in the ovary. Some germ-cell tumors have an isochromosome 12, where one arm of ...
Dysgerminoma is the most common type of malignant germ-cell ovarian cancer. Dysgerminoma usually occurs in adolescence and early adult life; about 5% occur in prepubertal children. Dysgerminoma is extremely rare after age 50. It occurs in both ovaries in 10% of patients and, in a further 10%, a microscopic tumor is in the other ovary. [citation ...

In the United States, uterine cancer is the most common invasive gynecologic cancer. [22] The number of women diagnosed with uterine cancer has been steadily increasing, with 35,040 diagnosed in 1999 and 56,808 diagnosed in 2016. The age-adjusted rate of new cases in 1999 was 23.9 per 100,000 and has increased to 27.3 per 100,000 in 2016. [26]
Vulvar cancer is a cancer of the vulva, the outer portion of the female genitals. [ 1 ] It most commonly affects the labia majora. [ 1 ] Less often, the labia minora, clitoris, or Bartholin's glands are affected. [ 1 ] Symptoms include a lump, itchiness, changes in the skin, or bleeding from the vulva.
Vaginal cancer is an extraordinarily rare form of cancer that develops in the tissue of the vagina. [1] Primary vaginal cancer originates from the vaginal tissue – most frequently squamous cell carcinoma, but primary vaginal adenocarcinoma, sarcoma, and melanoma have also been reported [2] – while secondary vaginal cancer involves the metastasis of a cancer that originated in a different ...
