Herpes simplex lymphadenitis: a case report and review of the published work.

Viral lymphadenitis may lead to a histological appearance that can simulate malignancy. The histological features of herpes simplex lymphadenitis have not previously been described in detail. We report a case of proved herpes simplex lymphadenitis in a 30 year old man which was characterised by a pronounced proliferation of immunoblasts. The microscopical findings are described and the published work is reviewed.
