| Summary: | <p>Abstract</p> <p>Background</p> <p>Tuberculosis. toxocariasis and toxoplasmosis are among the common infectious causes of lymphadenitis in children. Cases of <it>Toxoplasma gondii </it>and <it>Toxocara spp </it>co-infection have been reported.</p> <p>Case Presentation</p> <p>This case report describes a co-infection of <it>Toxoplasma gondii</it>, <it>Toxocara </it>spp and tuberculosis in a child with chronic lymphadenopathy and eosinophilia.</p> <p>Conclusion</p> <p>The case report highlights two important points. First is the diagnostic challenges that are encountered by clinicians in tropical countries such as Sri Lanka, where lymphadenopathy and eosinophilia with a positive serology commonly point towards a parasitic infection. Secondly the importance of proper history taking and performing the Mantoux test as a first line investigation in a country where the incidence of tuberculosis is low, even in the absence of a positive contact history.</p>
