Table 1. Carcinoma of the Vulvaa
| Stage I | Tumor confined to the vulva. |
| IA | Lesions ≤2 cm in size, confined to the vulva or perineum and with stromal invasion ≤1.0 mmb, no nodal metastasis. |
| IB | Lesions >2 cm in size or with stromal invasion >1.0 mmb, confined to the vulva or perineum, with negative nodes. |
| Stage II | Tumor of any size with extension to adjacent perineal structures (1/3 lower urethra, 1/3 lower vagina, anus) with negative nodes. |
| Stage III | Tumor of any size with or without extension to adjacent perineal structures (1/3 lower urethra, 1/3 lower vagina, anus) with positive inguino-femoral lymph nodes. |
| IIIA | (i) With 1 lymph node metastasis (≥5 mm), or |
| (ii) 1–2 lymph node metastasis(es) (<5 mm). | |
| IIIB | (i) With 2 or more lymph node metastases (≥5 mm), or |
| (ii) 3 or more lymph node metastases (<5 mm). | |
| IIIC | With positive nodes with extracapsular spread. |
| Stage IV | Tumor invades other regional (2/3 upper urethra, 2/3 upper vagina), or distant structures. |
| IVA | Tumor invades any of the following: |
| (i) upper urethral and/or vaginal mucosa, bladder mucosa, rectal mucosa, or fixed to pelvic bone, or | |
| (ii) fixed or ulcerated inguino-femoral lymph nodes. | |
| IVB | Any distant metastasis including pelvic lymph nodes. |
| aAdapted from FIGO Committee on Gynecologic Oncology.[2] | |
| bThe depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion. |
