A statistical study on clinical findings of solar keratosis.

Clinical findings were studied in 50 patients with 53 lesions of solar keratosis encountered during the 15 year period from 1977 to 1991. The majority of these cases were evident in the over-sixty age group (average 62.2 years). A greater proportion were females. Most lesions were observed on the face; especially on the cheek, and from the outer eyelid to the temple. The erythematous type (desquamative-keratotic) lesion was the most evident. With the exceptions of the years 1979 and 1991, no remarkable increase in the number of patients was noted during the 15 year period.
