Epidemiological study of basal cell carcinoma between 2010 and 2013, at a dermatology reference hospital in the city of Bauru, São Paulo State, Brazil

Introduction: Basal cell carcinoma is the most common skin cancer and corresponds to 70-80% of all malignant neoplasms of the skin. It is emerging as a global public health problem, with incidences of the condition increasing in all countries. Objective: To evaluate the epidemiological profile and characteristics of patients diagnosed with basal cell carcinoma in the previous four years in a reference hospital. Methods: A cross-sectional descriptive study was carried out at a dermatology reference center in the city of Bauru, São Paulo State, Brazil. Patients diagnosed with basal cell carcinoma, confirmed by histological examination from January 2010 to December 2013 were included in the study. The variables analyzed descriptively were: age at diagnosis, gender, city of origin, site of lesion, and race. Results: A higher incidence of basal cell carcinoma was observed in Caucasian women older than 60 years, with the malar and nasal regions arising as the usual locations. Conclusions: There is an increased incidence of basal cell carcinoma in young people, however the most affected population is still the elderly Caucasian population. The most common area for the cancer is the face, particularly the upper two thirds. The incidence of this cancer in younger populations is worrying, with the dermatologist having an important role in the prevention and early treatment.
