Clinical significance and epidemiological evolution of epitrochlear lymphadenopathy in pre- and post-highly active antiretroviral therapy era: A systematic review of the literature.

Epitrochlear lymphadenopathy is believed to be associated with distinct etiologies, however the evidence for the same is lacking. We systematically reviewed the reported causes of an enlarged epitrochlear lymph node and compared them over different time periods. Epitrochlear lymphadenopathy was encountered in a wide range of diseases, and we found no association with any particular disease.
