If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual
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 *Merkel Cell Carcinoma of Skin,* pages 177-180. * These primary sites are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged **Note 2:** Cancer of the perineum can be coded to several different primary site codes each of which includes sites other than perineum. 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. Merkel Cell Vulva only includes C510-C519 (vulva) and does not include primaries of the perineum in this schema. In addition, basal and squamous cell carcinomas of the skin of the perineum would be coded to C445 and would not be reportable. **Note 3:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Skin Except Eyelid* chapter on page 172 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=172).Main Data Items
