        DISEASE AND CAUSES PATHOPHYSIOLOGY SIGNS AND SYMPTOMS
        Vaginal cancer  
        • Cause unknown; tumor development has been linked to intrauterine exposure to diethylstilbestrol and to human papilloma virus
        Presents mainly as squamous cell carcinoma (sometimes as melanoma, sarcoma, and adenocarcinoma) and progresses from an intraepithelial tumor to an invasive cancer.
        • Abnormal bleeding and discharge
        • Firm, ulcerated lesion in the vagina
        Vaginismus  
        • Cause related to physical (hymenal abnormalities, genital herpes, obstetric trauma, or atrophic vaginitis) or psychological (conditioned response to traumatic sexual experience) factors
        An involuntary spastic constriction of the lower vaginal muscles.
        • Muscle spasm with pain when an object is inserted into the vagina
        • Lack of sexual interest or desire
        Variola  
        • Infection due to Poxvirus variola
        Virus is transmitted by respiratory droplets or direct contact. In the body, the virus replicates and causes viremia to develop.
        • Fever, vomiting, sore throat, CNS symptoms (such as headache, malaise, stupor, and coma), macular rash progressing to vesicular, and pustular lesions
        Velopharyngeal insufficiency  
        • Caused by an inherited palate abnormality or acquired from pharyngeal surgery or palatal paresis
        Impaired closure of the velopharyngeal sphincter between the oropharynx and the nasopharynx results in abnormal speech and nasal emission of air.
        • Unintelligible speech, hypernasality, nasal emission, poor consonant definition, and weak voice
        • Dysphagia and, if severe, regurgitation through the nose
        Vitiligo  
        • Cause unknown; usually acquired but may be familial (autosomal dominant)
        • Possible immunologic and neurochemical basis suggested
        Destruction of melanocytes (humoral or cellular) and circulating antibodies against melanocytes results in hypopigmented areas.
        • Progressive, symmetric areas of complete pigment loss with sharp borders, generally appearing in periorifical areas, flexor wrists, and extensor distal extremities
        Vulvovaginitis  
        • Caused by bacterial or viral infection, vaginal atrophy, or various traumas or irritations
        Infectious diseases and other conditions cause an inflammatory reaction of the vaginal mucosa and vulva.
        • Vaginal discharge (most common)
        • Appearance of discharge (consistency, odor, and color) varies with causative agent
        • May be accompanied by vulvar irritation, pain, or pruritus
