Zusammenfassung:It is described a case of a 10-month-old female mixed-breed cat with left ear discharge of approximately 6 days’ duration prior to the admission. Secretions were collected from both ears using a sterile swab for cytological and mycological analysis. A pyogranulomatous inflammatory infiltrate (predominantly characterized by the presence of neutrophils and macrophages) with the presence of cocci, rods and many yeast-like structures were seen on cytological analysis; the fungal culture confirmed the presence of the Sporothrix schenckii complex. Upon diagnosis of fungal otitis due to the S schenckii complex, treatment with oral itraconazole was administered. After 4 weeks of treatment, no S schenckii complex colonies were isolated, and clinical recovery had occurred. Although rare, clinicians must be aware of atypical presentations of sporotrichosis, as in this case of external otitis. This is of clinical relevance because this infection has been reported in several countries and is defined as a zoonotic disease.
