Vulva (ICD10 C51)

Tumour confined to the vulva

Lesions ≤ 2 cm in size, confined to the vulva or perineum and with stromal invasion ≤ 1.0 mm^a, no nodal metastasis

Lesions > 2 cm in size or with stromal invasion > 1.0 mm^a, confined to the vulva or perineum, with negative nodes

Tumour of any size with extension to adjacent perineal structures (lower third of urethra, lower third of vagina, anus) with negative nodes

Tumour of any size with or without extension to adjacent perineal structures (lower third of urethra, lower third of vagina, anus) with positive inguinofemoral nodes

Tumour of any size with extension to upper part of adjacent perineal structures, or with any number of nonfixed, nonulcerated lymph node.

Tumour of any size with disease extension to upper two-thirds of the urethra, upper two-thirds of the vagina, bladder mucosa, rectal mucosa, or regional lymph node metastases ≤5 mm

Regional lymph node ^b metastases >5 mm

Regional lymph node metastases with extracapsular spread

Tumour invades other regional (upper 2/3 urethra, upper 2/3 vagina), or distant structures

Disease fixed to pelvic bone, or fixed or ulcerated regional lymph node metastases
