Pyoderma gangrenosum in pediatric acquired immunodeficiency syndrome.

We describe two children with human immunodeficiency virus infection in whom pyoderma gangrenosum developed. Although pyoderma gangrenosum most commonly occurs in children with inflammatory bowel disease, it has also been described in patients with a variety of immunodeficiencies. In such patients a vigorous search to exclude a treatable infection should be made before the lesions are treated as pyoderma gangrenosum.
