Vulva
Vulva (including Skin of Vulva) (excluding Malignant Melanoma, Merkel Cell Carcinoma, Kaposi Sarcoma, Mycosis Fungoides, Sezary Disease, and Other Lymphomas)
C51.0-C51.2, C51.8-C51.9
   - C51.0  Labium majus
 
   - C51.1  Labium minus
 
   - C51.2  Clitoris
 
   - C51.8  Overlapping lesion of vulva
 
   - C51.9  Vulva, NOS
 
   - Note 1: This schema includes skin of Vulva but is NOT used for Malignant Melanoma, Merkel Cell Carcinoma, Kaposi Sarcoma, Mycosis Fungoides, Sezary Disease, or Other Lymphomas. Each of these diseases has a separate schema.
 
   - 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.  Collaborative Stage only includes C51.0-C51.9 (vulva) and does not include primaries of the perineum in this schema.  Basal and squamous cell carcinomas of the skin of the vulva are coded to C51.9 and are reportable; basal and squamous carcinomas of the skin of the perineum would be coded to C44.5 and would not be reportable.
 
   - Note 3:  AJCC 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.
