Localized herpes simplex lymphadenitis.

Despite the marked immunocompromised status of most affected patients, visceral herpes simplex virus (HSV) infections in adults remain localized to the esophagus, with only rare examples of dissemination. Lymph node involvement with herpes simplex has been noted in three reported cases, but only in the context of a widespread fatal infection. This report describes two patients who presented with localized herpetic lymphadenitis documented by light microscopy, immunohistochemistry, and DNA hybridization technics.
