Abstract
In a retrospective study of 581 patients with a diagnosis of Bowen''s disease (BD) treated over a 40-year period, we traced patient records to identify later diagnoses of nonskin-cancer. Fifty patients had nonskin cancer, as against an expected number of 40, but this difference was not significant. The lack of association was equally true for BD on sun-exposed and non-sun-exposed skin. Our findings support the view that BD is not a skin marker for internal malignant disease.
