Pyoderma gangrenosum leading to bilateral involvement of ears.

Pyoderma gangrenosum is a destructive inflammatory disease that commonly occurs in an idiopathic way. Its occurrence in the auricular area is very rare, although this fact does not seem to determine a different behavior of the disease with regard to ulcer aspects and response to treatment. The authors report the case of a patient with pyoderma gangrenosum affecting both earlobes. The patient responded well to treatment with oral prednisone and has not shown relapses after a six-month follow-up.
