Actinic cheilitis (AC) is a potentially malignant
disorder of the lip caused by exposure to solar radiation. It is a premalignant
condition that affects 40-year-old males more commonly. Diagnose must be based
on the histopathological exam, considering the degrees of dysplasia. Although
there is not an established protocol of treatment to AC, whenever there is
severe degrees of dysplasia the vermilionectomy is recommended. The aim of this
study is to report a case of AC with moderate dysplasia that was initially
treated with diclofenac in hyaluronic acid gel, but evolved to an intense dysplasia,
and then submitted to vermilionectomy. We concluded that vermilionectomy is the
treatment of choice in cases where there is intense dysplasia.
