ABSTRACT

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.


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.

ABSTRACT

Neste trabalho, descreve-se o diagnóstico e a conduta terapêutica aplicada em caso de dermatomicose e ceratite micótica causada por Exophiala sp em um cão com um ano e seis meses de idade. Os sinais clínicos incluíam alopecia, crostas, despigmentação e ulceração do plano nasal e focinho, e ceratite superficial bilateral no canto lateral dos olhos. Na cultura fúngica foi isolado Exophiala sp e o exame histopatológico da biopsia cutânea revelou dermatite nodular superficial e profunda granulomatosa. O tratamento com itraconazol sistêmico promoveu remissão dos sinais clínicos. Conclui-se que a realização de cultura fúngica e biópsia de pele são exames complementares eficazes no diagnóstico de dermatomicoses e que o emprego de itraconazol sistêmico pode ser efetivo no tratamento de dermatite fúngica e ceratite micótica causado por Exophiala sp em cão.


This report describes the diagnosis and the therapeutic conduct applied to the cases of subcutaneous dermatomycosis and mycotic keratitis caused by Exophiala sp in a one and a half year-old dog. The clinical signs included alopecia, crusts, dispigmentation, ulcerations in the nose and superficial bilateral keratitis in the corner of the eyes. In the fungal cultures, Exophiala sp was isolated and the microscopic analysis revealed characteristics of fungal dermatitis. Systemic therapy with itraconazole evidenced remission of clinical signs. The realization of fungal cultures and cutaneous biopsy are efficient complementary procedures in the diagnosis of dermatomycosis and that the usage of oral itraconazole can be effective in the treatment of fungal dermatitis and mycotic keratitis caused by Exophiala sp in dogs.
