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.
