Cat-scratch disease - Considerations for dentistry

Background. Cat-scratch disease, or CSD, results from inoculation of the gr ain-negative bacillus Bartonella henselae via a cat's scratch. A regional l ymphadenitis, which usually is cervical, develops and may progress to suppu ration. It is necessary to differentiate CSD from other lymphadenopathies. Case Description. A patient who had close contact with a cat subsequently d eveloped a localized, suppurative cervical lymphadenitis. As B. henselae wa s identified in 1992, the authors were able to confirm the existence of CSD serologically. Surgical drainage resulted in a successful resolution of th e disease process. Clinical Implications. As patients with CSD may be seen in the dental offic e, an awareness of its symptomatology can prevent unnecessary dental interv ention and facilitate early treatment.
