Anogenital malignancies and premalignancies are an important personal/public health problem due to their effects on individuals' physical, mental, and sexual health. Also, due to their etiological association with human papillomavirus (HPV) infection, anogenital malignancies and premalignancies constitute an immense public health burden. In addition to HPV infection, immunosuppression, HIV infection, chronic dermatoses, such as lichen sclerosis, previous radiotherapy and chemotherapy treatments, and smoking, are the other important etiopathologic factors in the development of anogenital malignancies and premalignancies. The incidence of anal squamous cell carcinoma (SCC) has increased considerably in the past decade, mainly due to the growing number of cases in high-risk groups, such as men who have sex with men, immunosuppressed individuals, and patients with HIV infection. Also, an increase in vulvar intraepithelial neoplasia (VIN) and VIN-related invasive vulvar cancer has been noted in women younger than age 50 years due to its association with HPV infections over the past decade. SCC of the scrotum seems to be the first cancer linked to occupational exposure. Bowen's disease, Bowenoid papulosis, and erythroplasia of Queyrat are the most widely seen premalignancies of anogenital region and are all forms of squamous intraepithelial neoplasia. Histopathologically, these conditions share identical histologic features of SCC in situ, but their clinical features differ. Early diagnosis is vital to improve prognosis, especially in anogenital malignancies. Also, if a delay occurs in diagnosis, treatment options used will be associated with significant negative effects on the patient's psychological well-being and quality of life; hence, management of anogenital malignancies and premalignancies should be organized in a multidisciplinary fashion.
