Pyoderma gangrenosum manifests as an ulceration of the skin often associated with several systemic diseases. The diagnosis is usually made by exclusion criteria with suggestions made by clinical findings and histological features. It can occur any site but more common in the legs. Advances in translational medicine led to the development of new forms of therapy in chronic inflammatory diseases by the oral administration of Janus kinase inhibitors. We report two cases of chronic ulceration of the skin consistent with the diagnosis of Pyoderma Gangrenosum that went into complete remission after the use of baricitinib.
