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 .


The commonest histological type by far is squamous cell carcinoma which account of ~80-85% of cases . The tumor commonly involves the labia majora and minora.

Risk factors
  • vulval intraepithelial neoplasia: considered a precancerous condition

Radiographic features


Particularly useful in accurately assessing the size (up to ~80 accurate ) of vulval lesion and assessing groin lymph node metastasis

Signal characterisitcs include:

  • T1: low to intermediate signal
  • T2: typically intermediate to high signal

The FIGO staging system is commonly adopted: see vulval cancer staging

Differential diagnosis

Considerations (particularly when lesions are large) include:
