This is a term that includes several conditions that are associated with the results of a pregnancy. The conditions are molar pregnancy, invasive mole, metastatic mole and gestational choriocarcinoma(korio carcinoma). These are cancers and cancer like conditions of placental elements. The concept is so far beyond most people's experience, that unless they have been to medical school they will never have heard of it. It is not uncommon.

Cancer of the vagina is rare. It is almost always a squamous cell cancer. The exception is an adenocarcinoma that occurs in women who were exposed to DES (diethylstilbestrol) in-utero. One of the reasons that it is rare is that cancers of the vagina that also involve the vulva are considered to be vulvar cancers; if it involves the cervix it is considered to be a cervical cancer. Vaginal cancer may cause symptoms of abnormal bleeding and foul discharge. Bleeding after intercourse is a symptom of cancer of the vagina as well as cancer of the cervix.

The cervix is the part of the uterus connected to the upper vagina. It is the structure that dilates during childbirth to allow the baby to traverse the birth canal. There are two major types of cancer that develop from the cervix. Squamous cell cancers arise from the squamous epithelium that covers the visible part of the cervix. Adenocarcinomas arise from the glandular lining of the endocervical canal.

Cancer of the vulva is not a common disease. There are about 4,000 new cases each year in the United States. Although it can occur in women in the third and fourth decade it is usually diagnosed in older women. Over 95% of vulvar cancers arise from the squamous epithelium. The remainder are mostly melanomas. The cause of squamous cancer of the vulva is unknown but there is a weak association with Human Papilloma Virus (HPV). The most important feature about vulvar cancers is the premalignant phase.
