Feo-hifomicose sistêmica em cão

ABSTRACT

The objective of this study was to describe clinical, laboratorial and histopathological findings of systemic phaeohyphomycosis in a dog. The animal was presented with a history of fatigue, ascites, lethargy, weight and appetite loss and polydipsia. The therapy for erliquiose and babesiosis was started. After 11 days, the dog returned with severe liver disease and died after forty-eight hours. At necropsy, there were black nodules in various abdominal organs. Histologically, necrotizing granulomatous reaction with hemorrhage associated with myriads of intralesional pigmented fungal hyphae was observed in multiple organs, characterizing systemic phaeohyphomycosis. Thus, it is important to include this illness in the differential diagnosis of severe liver diseases in dogs with ascites.

RESUMO

Descrevem-se os achados clínicos, laboratoriais e histopatológicos de feo-hifomicose sistêmica em um cão. Clinicamente observou-se cansaço, ascite, apatia, hiporexia, perda de peso e polidipsia. O animal estava sendo tratado para erliquiose e babesiose. Após 11 dias, o cão retornou com hepatopatia grave e veio a óbito em 48 horas. Na necropsia, observaram-se nódulos enegrecidos em vários órgãos da cavidade abdominal. Histologicamente, havia reação granulomatosa necrosante com hemorragia, associada a miríades de hifas fúngicas pigmentadas intralesionais em múltiplos órgãos, caracterizando feo-hifomicose sistêmica. Ressalta-se a importância de incluir esta doença no diagnóstico diferencial de hepatopatias graves em cães com ascite.
