A man with recurrent skin ulcerations.

Pyoderma gangrenosum is a rare, chronic, non infectious ulcerative skin disease. It is an inflammatory neutrophilic dermatosis. It is associated in 50% with a systemic disorder. Unfortunately, there are no randomized controlled studies concerning PG treatment. Immunosuppression is the mainstay of treatment and includes local and systemic measures, with high risk of potential side effects. Multidisciplinary care to patients with PG is essential for best management. We present a patient with pyoderma gangrenosum which was admitted in our Infectious Diseases Unit and first treated based on an infectious assumption. Collaboration between internists and dermatologists led to quick correct diagnosis, PG management, exclusion of an associated systemic disorder and management of further complications.
