title: Cat scratch disease during etanercept therapy.
abstract: Lymphadenopathy in a patient taking TNFalpha antagonist therapy may indicate lymph node tuberculosis or a hematological malignancy. Although histological evidence of granuloma suggests tuberculosis, many other infections responsible for granulomatous reactions have been reported in patients on TNFalpha antagonist therapy. We report a case of granulomatous lymphadenopathy due to Bartonella henselae in a patient taking etanercept to treat ankylosing spondylitis.
