Cat-scratch disease caused by Bartonella henselae: the first case report in Taiwan.
We report a typical case of cat-scratch disease caused by Bartonella henselae, in Taiwan. A 20-year-old man developed right axillary lymphadenopathy 2 weeks after being scratched on his right hand by a kitten. The axillary lymphadenopathy resolved gradually and spontaneously after 10 weeks without specific treatment. Serologic tests were not done during the acute stage of the event. However, an immunofluorescent antibody test performed during the convalescent stage was positive for B. henselae antibodies, and the concentration dropped by fourfold 2 months later. Histopathologic examination of a biopsy specimen from the right axillary lymph node revealed findings characteristic of cat-scratch disease including multiple foci of microabscesses surrounded by histiocytes and infiltration by plasma cells and lymphocytes. This is the first reported case of cat-scratch disease in Taiwan, with a history of contact with a cat, a positive serologic test for B. henselae infection and characteristic histopathologic findings of cat-scratch disease which met the criteria for diagnosis.
