Diseases of the vulva that are primarily erosive or ulcerative are uncommon. Notwithstanding, fissures or excoriations can occasionally complicate almost any dermatological disease of the vulva.
Common conditions such as dermatitis and psoriasis may become eroded by scratching, and allergic contact dermatitis often causes such severe oedema that blistering occurs.
Certain conditions, which are not usually ulcerative or bullous, may have rare variants that are, for example, the bullous variant of lichen sclerosus. Vulval cancer may ulcerate when advanced.
This chapter focuses on conditions where ulceration or erosion are a characteristic part of the disease. It is important to understand the difference between ulceration and erosion: ulceration means full-thickness loss of the epithelium, whereas erosion means partial-thickness epithelial loss.
