RESUMEN
A retrospective morphological research is made on the material of 78 cases from vulva for a three years period of time. They are identified 35 cases with invasive carcinoma, 2 c. with noninvasive carcinoma, 19 c. with vulvar dystrophia and squamous intraepithelial neoplasia (VIN). The invasive carcinomas are divided: keratinizing squamous cell carcinoma--31 c.; nonkeratinizing squamous cell carcinoma--3 c; adenoid squamous cell carcinoma--1. In all operated patients are examined the changes in the tissues surrounding the tumor and in the underlying tissue. They are divided in: lichen sclerosus, squamous cell hyperplasia, mixed dystrophia and squamous intraepithelial neoplasia. The morphological variants of squamous carcinoma, the epithelial changes and the patient's age are paralleled.
