[The early stromal invasion of the vulva (author's transl)].

Fourty one vulvectomy operation specimens and seventeen biopsies from the vulva were examined. They represented either dysplasias, carcinomata in situ or invasive squamous cell carcinoma. Slightly more than a third of the cases showed early stromal invasion as well in dysplasias and carcinomata in situ as in the margins of the invasive carcinomas. On the other hand the early stromal invasion of the vulva doesn't show that striking alterations as does that of the cervix uteri.
