| description | A vulva squamous cell carcinoma that is rapidly growing, self-limited, and characterized by the presence of a central crater that contains squamous cells. The proliferating squamous cells infiltrate the dermis below and produce keratin masses that are pushed towards the surface of the tumor. It is considered a variant of well-differentiated squamous cell carcinoma with distinct clinical behavior. |
