Intralesional amphotericin B in a cat with refractory localised sporotrichosis

The present report concerns a case of sporotrichosis in a 3-year-old male crossbred cat. After 9 months of oral itraconazole (20 mg/kg) therapy, all skin lesions had resolved with the exception of a single nodular lesion located on the bridge of the nose. Therefore, a combined therapy that included intralesional (IL) amphotericin B (1 mg/kg) was started. The lesion resolved completely after three weekly administrations of IL amphotericin B, given in concert with oral itraconazole. The cat remains well 1 year after discontinuing therapy, with no signs of recurrence.
