title: Scanning electron microscopy of dermatofibromas.
abstract: The three-dimensional morphology of six dermatofibromas was studied by scanning electron microscopy. Hypertrophic epidermal ridges covered with large keratinized cells overlay each dermal lesion. Small collagenous fibers in the tumors contrasted with the bundles of much larger collagenous fibers in the normal dermis peripheral to the lesions.
