Vaginal tumors

Vaginal tumors are neoplasms (tumors) found in the vagina. They can be benign or malignant. A neoplasm is an abnormal growth of tissue that usually forms a tissue mass. Vaginal neoplasms may be solid, cystic or of mixed type. Vaginal cancers arise from vaginal tissue, with vaginal sarcomas develop from bone, cartilage, fat, muscle, blood vessels or other connective or supportive tissue. Tumors in the vagina may also be metastases (malignant tissue that has spread to the vagina from other parts of the body).  Cancer that has spread from the colon, bladder, and stomach is far more common than cancer that originates in the vagina itself. Some benign tumors may later progress to become malignant tumors, such as vaginal cancers. Some neoplastic growths of the vagina are sufficiently rare as to be only described in case studies. Signs and symptoms may include a feeling of pressure, painful intercourse or bleeding.  Most vaginal tumors are located during a pelvic exam. Ultrasonography, CT and MRI imaging is used to establish the location and presence or absence of fluid in a tumor.Biopsy provides a more definitive diagnosis.

Squamous-cell carcinoma of the vagina is a potentially invasive type of cancer that forms in the tissues of the vagina. Though uncommon, squamous-cell cancer of the vagina (SCCV) is the most common type of vaginal cancer. It is further subdivided into the following subtypes: keratinizing, nonkeratinizing, basaloid, and warty. It forms in squamous cells, the thin, flat cells lining the vagina. Squamous cell vaginal cancer spreads slowly and usually stays near the vagina, but may spread to the lungs, liver, or bone. This is the most common type of vaginal cancer. SCCV accounts for approximately 85% of vaginal cancer cases and initially spreads superficially within the vaginal wall. It can later invade other vaginal tissues. The carcinoma can metastasize to the lungs, and less frequently in liver, bone, or other sites. SCC of the vagina is associated with a high rate of infection with oncogenic strains of human papillomavirus (HPV) and has many risk factors in common with cervical cancer.
