About 50% of cases of pyoderma gangrenosum (PG) are associated with a variety of systemic diseases. We describe a patient with severe PG on both legs who suffered from an autoimmune haemolytic anaemia in association with a congenital deficiency of complement factors C2 and C4. To the best of our knowledge, this constellation has not been previously reported.
