Abstract
In 2 patients, active chronic hepatitis was complicated by the development of pyoderma gangrenosum. The favorable response of the pyodermatous lesions to azathioprine therapy suggests that this drug may be of value in treating this disorder in patients for whom corticosteroid therapy produces no benefit or is contraindicated because of side effects. Azathioprine is also a potentially toxic drug and may need to be discontinued. Possible causal relationships between pyoderma gangrenosum and active chronic hepatitis are discussed.
