Negative pressure dressing in the management of pyoderma gangrenosum ulcer.

The clinical management of pyoderma gangrenosum (PG) ulcers has been a challenging practice since the description of these chronic wounds. Advances in biotechnology in the past 2 decades have given us a better understanding of the histopathologic nature of this disease, and as a result, better therapeutic modalities have evolved. However, on occasion PG ulcers will present in a refractory manner that will mandate additional strategies to attain wound closure. We present herein the novel use of negative pressure dressings to effectively treat such a complex wound.
