[Cancers of the oral and genital mucosa].

Squamous cell carcinomas account for over 90 % of cancers of the oral cavity in France. Alcohol and tobacco are the main risk factors. Delay in diagnosis is unfortunately frequent. The management of the cancer is based on surgery, possibly associated to radiation therapy and chemotherapy. The survival rate at 5 years does not exceed 30-40%. We hope to see a decrease in the number of oral cancer thanks to the development of preventive medicine (alcohol and tobacco cessation and early detection of potentially malignant lesions). Vulvar squamous cell carcinoma is a rare disease which traditionally affect elderly woman but continues to rise in incidence especially in younger women. There are at least 2 forms of genital squamous cell carcinoma. The most common form is found on older women arising in a background of lichen sclerosus and the second is associated with "high risk" human papillomavirus infection affecting younger women. A biopsy is usually required for diagnosis. Attempts to reduce genital cancer must focus on treating precursor lesions, namely lichen sclerosus and HPV-related intraepithelial neoplasia (VIN and PIN). Most genital cancer occur on undiagnosed or untreated lichens sclerosus, vulvar inspection when women attend for their cervical smears or seeking about significance of any chronic genital symptom by a clinical examination.
