Papular-purpuric "gloves and socks" syndrome is a distinctive dermatosis featuring acral pruritus, edema, and petechiae. It has been attributed in most--but not all--reported cases to Parvovirus B19 infection, on the grounds of serological proof of recent infection or detection of viral DNA by polymerase chain reaction in patient serum or biopsies. We report the immunohistochemical detection of Parvovirus B19 VP2 structural protein in the endothelial lining of dermal blood vessels in 3 examples of Papular-purpuric "gloves and socks" syndrome and review previously described immunohistochemical investigations in cutaneous involvement by this infection.
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.
