title: Multiple dermatofibromas: dermoscopic patterns.
abstract: Dermatofibromas are benign skin lesions that consist of pigmented papules or nodules. They produce the dimple sign when laterally squeezed and are usually found on the legs. These clinical features lead to the diagnosis in most cases. However, the differential diagnosis with other lesions, such as atypical nevi and melanoma can be difficult, and the dermoscopy may help the diagnosis. There are several dermoscopic patterns associated with dermatofibromas, the most common being a central white scar like patch with delicate pigment network at the periphery. This article describes the case of a patient who had eleven clinically similar dermatofibromas, with four distinct patterns when submitted to dermoscopic examination.
