[Solitary nontuberculous mycobacterial infection of a cervical lymph node caused by Bartonella henselae (cat scratch disease)].

Cat scratch disease (CSD) is a common cause of subacute regional lymphadenopathy. Cats are the principal reservoir of Bartonella henselae, the etiologic agent in most cases of CSD. Because the histopathological findings are typical but not specific, a wide range of other agents must be considered in differential diagnosis. We report on a patient with a solitary swelling of the neck which remained over months with initial features suggestive of unspecific lymphadenitis, but who, after careful history taking and further serological testing, had cat scratch disease.
