A case of early recovery from feline ceruminous cystomatosis after treatment with terbinafine-florfenicol-betamethasone acetate otic gel

Abstract

A 4-year and 4-month-old, intact male, British Shorthair cat presented with multiple black-to-gray dome-shaped nodular lesions on both external ear canals and the concave surface of the pinna. The case was diagnosed as feline ceruminous cystomatosis based on a histopathologic examination of the nodular tissue. As the owner found it difficult to perform topical therapy at home, the cat was treated with ear cleaning and the administration of a topical ear gel containing 1% florfenicol, 1% terbinafine, and 0.1% betamethasone acetate three times at our clinic. The lesions almost completely regressed within 3 months, and no recurrence was observed within 6 months after the final medication.
