EBV-associated cutaneous B-cell lymphoma is characterized by a long interval between the initiation of immunosuppression and the development of lymphoma. Although previous reports have reported an indolent clinical course, an aggressive clinical course may occur. HHV8 and lytic phase EBV antigens are detected in some cases, possibly suggesting a pathogenetic role.
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.
