Resumo
Background: Cryptococcosis is a mycosis that primarily affects domestic cats and is caused by fungi of the genus Cryptococcus, resulting in cutaneous, ocular, respiratory, and neurological manifestations. Diagnosis is based on the microscopicevaluation of the lesions and isolation of the causative agent. The aim of this study was to describe a case of feline cryptococcosis diagnosed by cytology and treated at the Veterinary Hospital of the State University of Santa Cruz (HV-UESC).Case: A 5-year-old uncastrated male cat was taken to the HV-UESC small animal clinic, owing to a gradual increase inthe volume of the nasal plane spanning over a year, accompanied by respiratory distress. Upon physical examination, theanimal was found to have regular nutritional status, dehydration, hypocorous mucosae, and enlarged popliteal lymph nodes.In addition, multifocal areas of ulceration on the body as well as increased volume in the nasal plane (clown nose) wereobserved. Peripheral blood samples were collected for complete blood count and biochemical analysis. Due to clinicalsuspicion of fungal lesions, fine needle aspiration of the nasal lesion was performed and cytological slides were sent tothe HV-UESC histopathology laboratory. Probable diagnoses included rhinosporidiosis, cryptococcosis, and histoplasmosis. The animal was subjected to thoracic radiography in the imaging division of the HV-UESC. Blood counts revealedthrombocytopenia (130,000/mm3) and biochemical tests presented hypoproteinemia (3.2 g/dL), with hypoalbuminemia(1.52 g/dL); however, chest radiography did not show pulmonary alterations. Results of cytological analysis indicatedpyogranulomatous inflammation associated with intracellular organisms, demonstrating a pathogen morphology similarto that of Cryptococcus spp. Before the diagnosis, itraconazole1 5 mg/kg (1 capsule, twice a day for 30 days) and fipronil2(1 ampoule 0.5 mL, on the back) were prescribed...
