New insights into delusional infestation.

Abstract

The recently proposed Koo-Brownstone staging system for Delusional Infestation (DI) is a large step forward in Dermatology. It proposes that patients' presentations can be separated into various categories along a spectrum, and that each of these categories are approached differently. This system explains longstanding variation in the reported response to treatment of patients who present with concerns of infestation. To develop a consensus across the medical community, the authors propose that the terms are discussed in a larger forum of national experts. The authors also suggest the avoidance of the term "Morgellons" within this staging system.
