what are non-neoplastic epithelial lesions of vulva?
lichen sclerosus (increased risk of SCC) lichen simplex chronicus
neoplastic lesions of vulva
squamous dysplasia (condyloma, VIN)
carcinoma of vulva (sq cell, adeno, basal cell, melanoma)
paget disease
mesenchymal lesions
lichen sclerosus is seen commonly in what age group
premenarchal or postmenopausal
symptoms of lichen sclerosus
painful, pruritic
thin epidermis (shiny)
leukoplakia
histology of lichen sclerosus
thin epidermis
fibrotic dermis, chronic inflam cell infiltrate
lichen simplex chronicus develops secondary to
chronic irritation underlying inflammatory dermatosis
histology of lichen simplex chronicus
epithelial thickening
hyperkeratosis
dermal chronic inflam
condyloma accuminata in vulva
VIN-1 (warty lesion)
high grade vulvar intraepithelial neoplasia
VIN2, VIN3
HPV associated-16,18
histology for vulvar dysplasia
in full thickness dysplasia: nuclear atypia, high nuclear to cyto ratio, abundant mitosis
types of vulva carcinoma
90% is sq cell carcinoma
adenocarcinoma, basal cell, malignant melanoma
two distinct forms: high risk HPV associated (preceded by VIN), older age group (preceded by reactive changes like lichen sclerosis)
extramammary Paget’s dis
red scaly plaques
intraepidermal prolif or malignant cells
large pale cells in epidermis (glandular)
