Cutaneous squamous cell carcinoma with epidermodysplasia verruciformis-like features in a patient with Schimke immune-osseous dysplasia K E Y W O R D S : acquired epidermodysplasia verruciformis, Schimke immune-osseous dysplasia, squamous cell carcinoma Schimke immune-osseous dysplasia 1 (SIOD) is an autosomal recessive disorder caused by mutations in the SMARCAL1 gene encoding an ATP-driven annealing helicase that stabilizes stalled replication forks and facilitates DNA repair during replication. 2 The syndrome is characterized by spondyloepiphyseal dysplasia, steroid-resistant nephropathy and cellular immune deficiency. Additional features include cerebral ischemic events, microdontia, short stature, hyperpigmented macules on the trunk and extremities and characteristic dysmorphic features such as a broad, depressed nasal bridge and a broad nasal tip. Renal pathology shows focal segmental glomerulosclerosis; BRIEF COMMUNICATIONS 465 ORCID Mary-Katharine Collins
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.
