Familial Pyoderma Gangrenosum: About 2 cases

Pyoderma gangrenosum occurrence in a familial pattern is extremely rare. We report pyoderma gangrenosum in two Tunisian siblings with onset respectively at 28 and 26 years old. The initial lesion was a pustule that breaks down to form an ulcer with an erythematous border. Treatment with oral corticosteroids induced an excellent clinical response. This familial clustering suggests a possible genetic role in the development of pyoderma gangrenosum in some cases.
