title: Pigmented Bowen's disease arising from pigmented seborrheic keratoses.
abstract: We report three cases of pigmented Bowen's disease that clinically and histologically had features of seborrheic keratoses. We speculate about the mechanism of pigmentation in these lesions and suggest that they arise from pigmented seborrheic keratoses.
