[Cat scratch disease: a diagnosis to be aware of!].

Subacute cervical lymphadenopathy among young adults may be of an infectious or malignant aetiology. We report two cases of young males with chronic cervical lymphadenopathy. A diagnosis of Cat scratch disease (CSD) was made by serological and molecular studies. CSD is one of the most frequent infectious lymphadenopathies among young people. Diagnosis of CSD is dependent on clinical, epidemiological, molecular and histological criteria. The detection of antibodies to Bartonella Henselae and the amplification of its DNA by Polymerase Chain Reaction (PCR) are the two main methods of laboratory diagnosis. The evolution of CSD is usually benign; however therapeutic management remains problematic, particularly in atypical forms.
