[Hepatosplenic cat-scratch disease in the immunocompetent adult].

Atypical manifestations of cat-scratch disease have been described in children and immunosuppressed adults. We report the first case of hepatosplenic cat-scratch disease in an immunocompetent subject, demonstration of diversity of this infection. A 33-year-old man presented with prolonged fever, lymphadenopathy and multiple hypodense lesions of liver and spleen in ultrasonographic imaging. The hepatic biopsy showed non-specific inflammatory reactions including granulomata and stellate necrosis. Anti-Bartonella antibodies have been found. The therapy with clarithromycin and doxycycline for many weeks was effective for hepatic lesions. A month ago a history of a cat contact with the presence of a skin lesion has been reported.
