Cytomegalovirus lymphadenitis mimicking a relapsed diffuse large B‐cell lymphoma

Abstract

Cytomegalovirus (CMV) reactivation is frequent after autologous stem cell transplantation (ASCT), but generalized CMV lymphadenitis is rare. We report a CMV lymphadenitis after an ASCT mimicking a relapse of a diffuse large B‐cell lymphoma. After histopathological documentation, CMV lymphadenitis should be treated to avoid systemic progression.
