Abstract

Histoplasmosis is a systemic fungal infection caused by the dimorphic fungus Histoplasma capsulatum that infects humans and a wide variety of mammalian species, including cats.  In Brazil only four cases of this disease were reported in domestic cats. The present study reports a case of an indoor cat, rescued from street three years ago, that developed histoplasmosis with supraorbital involvement. The cat presented sneezing, dyspnea and increased respiratory sounds and the diagnosis suspected was allergic rhinitis. Prednisolone and amoxicillin were prescribed. The patient returned to clinic after clinical signs worsened with a swelling of the right supraorbital region, unilateral left side conjunctivitis and enlarged submandibular lymph nodes. Cytology and culture revealed Histoplasma capsulatum. Initially, itraconazole (10 mg/Kg SID orally) was prescribed and due to the worsening of clinical signs, was combined amphotericin B (0.5 mg/kg SC) for two weeks. The therapy with amphotericin was discontinued and itraconazole continued to be administered for six months. The clinical signs were resolved and no recrudescence was reported. It is important that veterinary practitioners to be aware of the clinical features of feline histoplasmosis and consider the possibility of a subclinical infection.
