[The aged scalp : A dermato-oncological focus point].

Non-melanoma skin cancer and its precursor lesions are common diagnoses in dermatological practice, due to rising incidence and prevalence. Diagnosis is often clinical with subsequent histological confirmation. First-choice treatment for invasive carcinomas is complete surgical excision. Other therapeutic options, such as radiation or systemic therapies, should only be considered when excision is impossible. Mostly located on parts of the scalp that are poorly visible and accessible, particularly for elderly patients, these lesions are a challenge for physicians and patients alike. Especially regarding precursor lesions, the therapeutic options are numerous and should be adapted to the individual patient. The main risk factor for development of non-melanoma skin cancer and its precursor lesions is chronic UV exposure. A possible occupational context should always be considered. Preventative methods based on patient education and adequate sun protection behavior are particularly important. The prognosis of non-melanoma skin cancer improves significantly with early diagnosis, as well as with guideline-compatible treatment and follow-up.
