The risk factors studied were sun exposure, smoking, actinic skin, photo aging and associated dermatoses. Results: the predominant precancerous dermatoses were actinic keratosis (41.7%) and senile atrophy (44.9%). The exposed areas were the most frequent. The most frequent associated diseases were other dermatoses and non-communicable chronic diseases. The outstanding risk factors were sun exposure (70.3%), actinic skin (41.3%) and photo aging (38.6%). Conclusions: the most common types of skin diseases found were senile atrophy and actinic keratosis as well as the types I and II of the skin, associated with the following risk factors: prolonged sun exposure, actinic skin and photo aging.
