Final answer:
Dysplastic vulvar lesions can show atypical cells with various characteristics, including nuclear enlargement and irregular arrangement, differentiating them from normal tissue.
Step-by-step explanation:
The microscopic appearance of dysplastic vulvar lesions can include atypical cells confined to the basal layer, full-thickness involvement of atypical cells, and hyperkeratosis without cellular changes. In dysplastic vulvar lesions, atypical cells are not confined to the basal layer, which differentiates them from normal tissue. These atypical cells may exhibit nuclear enlargement, hyperchromasia (darkly stained nuclei), and an irregular arrangement.
