title: Alpha1-antitrypsin deficiency with severe panniculitis. Report of two cases.
abstract: Two patients with profound decrease of alpha1-antitrypsin (PiZZ) presented with severe pannicultis (Weber-Christian disease); one had systemic panniculitis including pancreatitis. Another possible case is quoted from the literature. Although milder forms of panniculitis can have normal Pi phenotypes and alpha1-antitrypsin levels, the marked reduction of antiproteolytic activity found in PiZZ homozygotes may predispose to or aggravate the lesions of Weber-Christian disease.
