Table of Neoplasms

The code C51.8 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients

Vulvar Cancer

Vulvar cancer is a rare type of cancer. It forms in a woman's external genitals, called the vulva. The cancer usually grows slowly over several years. First, precancerous cells grow on vulvar skin. This is called vulvar intraepithelial neoplasia (VIN), or dysplasia. Not all VIN cases turn into cancer, but it is best to treat it early.

Often, vulvar cancer doesn't cause symptoms at first. However, see your doctor for testing if you notice

A lump in the vulva
Vulvar itching or tenderness
Bleeding that is not your period
Changes in the vulvar skin, such as color changes or growths that look like a wart or ulcer

You are at greater risk if you've had a human papillomavirus (HPV) infection or have a history of genital warts. Your health care provider diagnoses vulvar cancer with a physical exam and a biopsy. Treatment varies, depending on your overall health and how advanced the cancer is. It might include surgery, radiation therapy, chemotherapy, or biologic therapy. Biologic therapy boosts your body's own ability to fight cancer.
