Notes

C510 Labium majus C511 Labium minus C512 Clitoris C518 Overlapping lesion of vulva C519 Vulva, NOS **Note 1:** This schema is based on the UICC chapter *Vulva,* pages 197-201. * This classification applies to primary carcinomas of the vulva. A carcinoma of the vulva that has extended to the vagina is classified as carcinoma of the vulva **Note 2:** Involvement of the vulva and perineum should be assigned to vulva as the primary site in the absence of a statement that the tumor extended from the perineum to the vulva. This schema only includes C510-C519 (vulva) and does not include primaries of the perineum. Basal and squamous cell carcinomas of the skin of the vulva are coded to C519 and are reportable; basal and squamous carcinomas of the skin of the perineum would be coded to C445 and would not be reportable. **Note 3:** The FIGO stages are based on surgical staging. (TNM stages are based on clinical and/or pathologic classification). **Note 4:** TNM values correspond to the stages accepted by the Federation Internationale de Gynecologic et d'Obstetrique (FIGO). Note that FIGO uses a single stage value which corresponds to different groupings of T, N, and M values. **Note 5:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Vulva* chapter on page 198 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=198).
