ObjectivesObjectives
In this series of lectures we will ascend the In this series of lectures we will ascend the female reproductive tract from the vulva to female reproductive tract from the vulva to ovaries. At each anatomic site we will discuss ovaries. At each anatomic site we will discuss the major clinical conditions including the major clinical conditions including physiological, inflammatory, infectious and physiological, inflammatory, infectious and neoplastic disorders. Two hours will be neoplastic disorders. Two hours will be devoted to sexually transmitted infections. devoted to sexually transmitted infections. There will be an emphasis on major There will be an emphasis on major characteristics of tumors at each site and characteristics of tumors at each site and pathogenic mechanisms of non-neoplastic pathogenic mechanisms of non-neoplastic disease.disease.

Vulvar Dystrophy (leukoplakia)Vulvar Dystrophy (leukoplakia)
Dry-appearing, white patches on vulvar skin
Vulvar dystrophy is a common clinical entity with several etiologies making Bx of the affected area necessary.
Vulvar Dystrophy affecting perineal skin
One of the most common causes of leukoplakia is lichen sclerosus et atrophicus
Lichen sclerosus: atrophic epidermis and homogenized collagen within dermis
Mild inflammation in lichen sclerosis
Atrophic adenexal structures in lichen sclerosis
Lichen Simplex Chronicus with hyperkeratosis & epidermal hyperplasia
