Conference summary
The incidence of different Skin Cancers has been increasing. In Portugal there are currently more than 13,000 new cases per year, with more than 1,000 cases of Melanoma.
In addition to genetic factors and phototype, environmental factors stand out, in particular exposure to Ultraviolet (UV) B and A cumulatively, whether in recreational or professional activities or exposure to solariums, as well as immunosuppression.
Among the precursor lesions of Skin Cancer, actinic keratoses stand out, the main precursors of Squamous Cell Carcinomas, the second most frequent skin cancer, with potential for lymph node and systemic involvement.
Basal Cell Carcinomas are the most frequent skin cancers, whose malignancy is mainly local. Melanomas, being less frequent, are potentially more serious due to the risk of systemic metastasis if they are not excised at an early stage.
Most Carcinomas occur on the face, scalp and neck. Clinical recognition and early diagnosis of the different forms of Skin Cancer are essential, dermoscopy being important in the differential diagnosis and histopathology indispensable in the face of any diagnostic doubt.
Early and effective treatment is essential for a good prognosis. In the labial and oral mucosa, in addition to genetic factors and UVs, smoking, alcohol and HPV infection are relevant factors in the etiopathogenesis of Oral Mucosal Cancers, particularly in squamous cell carcinomas.
