Successful treatment of Schamberg's disease with fractional non-ablative 1540 nm erbium:glass laser.

Schamberg's disease is one of the pigmented purpuric dermatoses (PPD). PPD encompass a large and heterogeneous group of dermatologic disorders featuring purpuric lesions often located on the lower limbs. The various forms of PPD are notoriously known to be resistant to treatment. Fractional photothermolysis has been described as a successful and safe method to induce dermal remodeling. We report three patients with Schamberg's disease who were successfully treated with 4 monthly sessions of fractional non-ablative 1540 nm erbium:glass laser, with resolution of their purpuric pigmented rash lasting up to 9 months after the last treatment session.
