BACKGROUNDActinic cheilitis (AC) is a potentially malignant disorder of the
lip caused by chronic exposure to ultraviolet radiation from the sun.OBJECTIVESTo evaluate the clinical, demographic, morphological and therapeutic management in
AC cases data associating to the histopathological grading.METHODSDemographic, clinical and management data of 161 patients with AC were analyzed.
In biopsied cases, two calibrated examiners performed histopathological grading by
binary system.RESULTSThere was a prevalence of males (79.5%), aged 40 years or older (77.5%),
light-skinned (85.7%), experiencing occupational exposure to sunlight (80.3%),
with AC presenting clinically as white lesions (33.6%). Conservative treatment was
adopted in 78 cases and biopsy in 83 cases (60.2% graded as low-risk AC). There
were no significant associations between histopathological grading and gender (p=
0.509), age (p=0.416), ethnicity (p=0.388), occupational exposure to sunlight
(p=1.000) or clinical presentation (p=0.803).CONCLUSIONThis study reinforces the hypothesis that demographic and clinical characteristics
of AC are not related to histopathological grading. Advice on protection from sun
exposure should be encouraged to avoid progression of AC and invasive
therapies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
