Shamberg disease is a pigmented dermatosis, also named progressive pigmentary dermatosis. It was initially described by Shamberg in 1901. It is characterized by diffuse, irregular macules of petechiae, composed of small, discrete red-brown macules named “cayenne-pepper” spots. The exact pathogenesis is still unknown. We report clinical, dermoscopic and histopathological findings of two new cases Shamberg disease and we highlight the importance of a proper diagnosis.
