The association of alpha-1 antitrypsin deficiency (PiZ phenotype) with systemic nodular panniculitis has been well documented. Despite reports of cases of systemic nodular panniculitis associated with other alpha-1 antitrypsin deficiency phenotypes, it is still not known if this association is fortuitous rather than causal. We report a case of systemic nodular panniculitis associated with alpha-1 antitrypsin deficiency (PiSS phenotype), with clinico-pathological features similar to those reported in cases associated with the PiZ phenotype.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
