ABSTRACT

Pyoderma gangrenosum is a painful, chronic, ulcerating skin disease associated with a wide variety of disorders, including Crohn's disease, ulcerative colitis, and Behcet's disease. Etiology of pyoderma gangrenosum is unknown but the lesions frequently appear at points of trauma and it is related with pathergy.
