[Actinic cheilitis in Quinta fishing workers: prevalence and associated histopathological aspects].

Abstract

The purpose of the present investigation was to study the occurrence and degree of severity of the actinic cheilitis in a sample of 566 artisan fishermen of Valparaíso, Chile. The condition was found in 43% of the sample, the degree of severity was an 8% for the acute expression and a 35% for the chronic type of the disease. A direct relationship between the number of years spent on sun exposure and the degree of severity of the vermillion alterations was found, being the patients between 16 and 45 years old the group most severely involved, a finding similar to the data reported in the current literature. The prone complexion was the fair one: those fishermen with blond or red hair, blue or green eyes and fair skin showed both clinical and histopathologically early disturbances of degenerative nature in the collagenous component of the connective tissue and in the epithelial surface.
