History
A 55-year-old white woman presented to our out-patient
department with a 4-year history of an asymptomatic eruption on her
lower extremities. The number and size of the lesions have been
increasing gradually over the last years. Multiple actinic
keratoses were diagnosed by her dermatologist, and she had been
treated with various topical glucocorticoids, retinoic acid and the
frequency-doubled Nd:YAG laser without benefit. Her medical history
included arrhythmias and regular use of digoxin, acetylsalicylic
acid and diuretics for the last 3 years. There was no history of
excessive sun exposure. There was no family history of skin
diseases.
