7歳男児に生じた猫ひっかき病の1例

抄録

  Cat-scratch disease (CSD) is a zoonosis characterized by lymphadenopathy in a patient with a history of cat contact. CSD is caused by Bartonella henselae infection and is a common cause of regional lymphadenopathy. The manifestations include erythema or papules at the site of injury and regional lymphadenitis in the initial stage of infection.
  We report the case of a seven-year-old boy who presented with swelling of the buccal. CT showed extensive lymphadenopathy in multiple lymph nodes in the buccal and submandiblar regions. He had a history of contact with cats. Serologic examinations for IgG and IgM titers to Bartonella henselae were performed by an indirect fluorescence assay. This assay revealed positive serum antibody titers for Bartonella henselae.
  On the basis of these results, CSD was diagnosed, and the patient was given an antibiotic for 14 days. After that, the patient recovered, with no recurrence.
