CHAPTER 7<br />

Tumours of the Vulva<br />

Squamous cell <strong>carcinoma</strong> of the vulva occurs predominantly in<br />

the older age group. Although the incidence rate of vulvar<br />

intraepithelial neoplasia is increasing, that of squamous cell<br />

<strong>carcinoma</strong> of the vulva is declining, reflecting earlier detection<br />

and more successful treatment. In addition to human papillomavirus<br />

infection, cigarette smoking is a putative risk factor for<br />

vulvar squamous cell <strong>carcinoma</strong>. There are three known precursor<br />

lesions: vulvar intraepithelial neoplasia, lichen sclerosis<br />

and chronic granulomatous disease.<br />

Other important epithelial malignancies of the vulva are Paget<br />

disease and Bartholin gland <strong>carcinoma</strong>. They are much less<br />

common than squamous lesions, and the risk factors are largely<br />

unknown.<br />

Prominent non-epithelial tumours are malignant melanoma and<br />

sarcoma botyoides.
