title: Collarette scaling in pityriasis rosea demonstrated by digital epiluminescence dermatoscopy.
abstract: Collarette scaling is a characteristic sign in pityriasis rosea. The use of digital epiluminescence dermatoscopy is proposed to assist in the recognition of this sign as this technique can magnify the lesions, eliminate other epidermal changes, and demonstrate the morphology and direction of scaling.
