Cat-scratch disease: considerations for dentistry.

BACKGROUND: Cat-scratch disease, or CSD, results from inoculation of the gram-negative bacillus Bartonella henselae via a cat's scratch. A regional lymphadenitis, which usually is cervical, develops and may progress to suppuration. It is necessary to differentiate CSD from other lymphadenopathies. CASE DESCRIPTION: A patient who had close contact with a cat subsequently developed a localized, suppurative cervical lymphadenitis. As B. henselae was identified in 1992, the authors were able to confirm the existence of CSD serologically. Surgical drainage resulted in a successful resolution of the disease process. CLINICAL IMPLICATIONS: As patients with CSD may be seen in the dental office, an awareness of its symptomatology can prevent unnecessary dental intervention and facilitate early treatment.
