Disseminated superficial actinic porokeratosis: a clinical study.
Disseminated superficial actinic porokeratosis is an autosomal dominant condition that requires sun exposure for full expression. It affects only sun-exposed areas, with relative sparing of the face. In sun-damaged skin of Australians disseminated superficial actinic porokeratosis is commonly mistaken for solar keratosis. Twenty-nine subjects with disseminated superficial actinic porokeratosis were involved in an extensive questionnaire and clinical study. The distribution of lesions was charted on all subjects, with a mean count of 268 lesions per subject. We found no evidence that skin cancer had arisen in disseminated superficial actinic porokeratosis lesions. A review of the etiologic and clinical features of disseminated superficial actinic porokeratosis also is presented.
