Congenital hemidysplasia with ichthyosiform erythroderma and limb defects (CHILD) syndrome is a rare X‐linked dominant disorder of cholesterol synthesis characterized by unilateral ichthyosiform dermatitis with ipsilateral limb hypoplasia. Recently, pathogenesis‐based treatment has demonstrated improvement of skin lesions with statins by decreasing formation of cholesterol intermediates through inhibition of cholesterol synthesis. We report a 10‐month‐old girl who presented with unilateral scaly ptychotropic plaques, who experienced rapid, near‐complete clearance with topical 5% simvastatin monotherapy twice daily.
Macular lymphocytic arteritis (MLA) is an indolent cutaneous small-medium-vessel vasculitis characterized by widespread asymptomatic livedo racemosa. A number of serologic abnormalities have been reported including an elevated erythrocyte sedimentation rate and antibodies associated with antiphospholipid antibody syndrome. We present a case of MLA with multiple serologic abnormalities, including those that have yet to be reported, such as anti-U1 ribonucleotide protein, anti-RNA polymerase III, anti-smith, and anti-proteinase 3 antibodies. We also provide a brief review of this unfamiliar entity with a focus on the appropriate workup.
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.
