Pyoderma gangrenosum (PG) is a common manifestation of inflammatory and neoplastic disorders. Clinically, these lesions appear as deep ulcers that are extremely slow to heal. It may occur cutaneously as well as viscerally 1. These lesions may be due to defects that prevent normal resolution of inflammation. No universally effective therapy exists for PG.The index patient had an unusually severe case of PG, involving viscera as well as skin. In order to gain insight into the signaling processes underlying PG, we analyzed the production of vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang-2), as well as a transcription factor upstream of these molecules, hypoxia inducible factor 2-alpha (HIF2a). We then stained additional samples from 3 additional patients to determine whether our findings can be generalized to PG. High level expression of VEGF and HIF2a was observed in all lesions. Ang-2 was focally positive in PG lesions
