RESUMO
O diagnóstico diferencial das linfadenomegalias supuradas deve se basear na historia clínica e em exames complementares, principalmente na análise histopatólogica. A Bartonella henselae, bastonete gram-negativo fastidioso que frequentemente causa bacteriemia em gatos, constitui agente que sempre deve ser associado a linfadenomegalia. Os gatos são reservatórios importantes desse microrganismo. A doença da arranhadura do gato normalmente cursa com poliadenopatias relacionadas ao local de inoculação (por arranhadura ou lambedura) e sintomatologia geral leve, sendo normalmente autolimitada. Raramente a doença complica com acometimento visceral, ocular e neurológico. Em alguns casos, há poliadenopatia persistente e supurada. Este relato apresenta as alterações descritas por mulher de 79 anos, com poliadenopatia cervical ulcerada, surgida após contato próximo com felino. As alterações clínicas e histopatológicas foram sugestivas de doença da arranhadura do gato, de evolução prolongada. Houve boa resposta a antimicrobianos. Este trabalho ilustra o amplo diagnóstico diferencial de linfadenomegalias persistentes, que deve incluir sempre a infecção pela Bartonella henselae entre as prováveis etiologias.
ABSTRACT
Differential diagnosis of suppurative lymphadenomegalies must be based on clinical history and laboratory tests, particularly in histhopatological analysis. The Bartonella henselae is a fastidious gram-negative rod-shaped bacterium that commonly causes bacteremia in cats, frequently associated with lymphadenopathy. Cats are important reservoirs of this organism. Cat scratch disease usually happens with polyadenopathies related to the inoculation local (by scratching or licking) and general light symptoms, besides being selflimiting. This disease is rarely complicated with visceral, ocular and neurological injuries. Some cases show persistent and festering polyadenopathy. This report shows changes described by a 79 old-year-woman, who presents ulcerated cervical polyadenopathy, acquired after close contact with cats. Clinical and histopathological changes were suggestive of cat scratch disease, of long time evolution. There was good response to antibiotics. This paper illustrates the wide differential diagnosis of persistent lymphadenomegalies, which should always include infection with Bartonella henselae among several etiologies.
