Primary vulval cancer is a rare gynecological malignancy that originates from the vulva.
It accounts for ~3-5% of female genital tract malignancies and typically presents in postmenopausal patients peaking around the age of 65-70 years of age 1.
The commonest histological type by far is squamous cell carcinoma which account of ~80-85% of cases 1. The tumor commonly involves the labia majora and minora.
- vulval intraepithelial neoplasia: considered a precancerous condition
Particularly useful in accurately assessing the size (up to ~80 accurate 3) of vulval lesion and assessing groin lymph node metastasis
Signal characterisitcs include:
- T1: low 4 to intermediate 1 signal
- T2: typically intermediate 4 to high 1 signal
The FIGO staging system is commonly adopted: see vulval cancer staging
