[Pyoderma gangrenosum associated with hidradenitis suppurativa: a case report and review of the literature]

Abstract

Pyoderma gangrenosum is an inflammatory disease that has been found to be associated with many systemic illnesses. The case presented here is of a man with a 20-year history of hidradenitis suppurativa who developed pyoderma gangrenosum. The pyoderma lesions appeared as a single outbreak which resolved totally after immunosuppressive treatment. This association has been reported only rarely in the literature. Furthermore, in the cases reported, no relationship was apparent between the activity of both diseases. In all cases the clinical course appeared independent, with no apparent overlap in inflammatory activity or response to the drugs administered.
