title: [Basal cell carcinomas].
abstract: Basal cell carcinomas (BCC) are the most common cancers and represent 80% of non-melanoma skin cancer and one third of cancers diagnosed per year. The main risk factor for these carcinomas is represented by excessive sun exposure compared to the phototype of the patient, which explains their location mainly on sun-exposed areas (head and neck). This location makes it necessary to consider the aesthetic and functional aspect of their care in addition to oncological treatment. The standard treatment for BCC is based on their surgical excision with histological healthy margins, done in most cases as an outpatient under local anaesthesia. However, the BCC are causing very heterogeneous situations because of their many clinicopathologic forms. New therapeutic options are increasingly available. Prevention is based on sun protection and early detection of lesions in patients at risk (light phototype).
