Clinicopathological study of 21 cases of eyelid actinic keratosis.
BACKGROUND
Actinic keratosis (AK) is an intraepidermal malignancy precursor form of cutaneous squamous cell carcinoma (SCC), which generally occurs in fair-skinned individuals with long-term sun exposure. We present a case series of AKs on the eyelid.


METHODS
This was a retrospective study. Data of patients seen from 1994 to 2005 were used in the analyses.


RESULTS
There were 21 cases of eyelid AKs in 18 patients, 11 men, and seven women, with a mean age of 70 (range 43-80) years. Most tumors were located on the upper eyelid. The mean size was 0.8 +/- 0.4 cm. The most frequent AK type was type I (76.2%). Men had bigger lesions and more frequent free-margin eyelid involvement.


CONCLUSIONS
In our series, tumors were more frequent and had worse clinical and histopathological features in men. AKs are closely related to SCC and need to be removed before they turn into SCC. They can be safely and effectively removed, and therapy is therefore warranted.
