Aneurysmal dermatofibroma: dermatoscopic aspects

Aneurysmal DF is considered a benign tumor of origin in the dermis and represents less than 2% of dermatofibromas, 1-5 it etiology is unknown, it is more prevalent in women over 30 years old. Histopathology gives the definitive diagnosis. The DF is generally larger than the classic DF, has an erythematous-brown or violet color, and can be painful if the lesion grows rapidly. With dermoscopy, we can identify any of the patterns already known to classical DF, but what will suggest that it is an aneurysmatic DF are the linear white structures, vascular structures and delicate pigmented network on the periphery.
