The Other Itch That Rashes: a Clinical and Therapeutic Approach to Pruritus and Skin Picking Disorders

摘要

Patients with skin picking disorders (SPDs) have historically been an under recognized and under treated group. Originally classified an impulse control disorder, skin picking disorder is now considered under the obsessive-compulsive disorder (OCD) and obsessive-compulsive-related disorder (OCRD) spectrum. Workup of SPD concentrates on differentiating this condition from primary skin disorders, systemic conditions associated with pruritus, and psychocutaneous syndromes. It is important to first address any underlying pruritic disorders (if present) that may be a trigger to pick the skin. First-line treatment for SPD is cognitive behavioral therapy. When necessary, pharmacologic therapy can be helpful as well.
