299. The many faces of pyoderma

Send me a question or story!For how common we see pyoderma in cats and dogs in veterinary practice, the appearance can be variable. A cutaneous bacterial infection can appear as crusting, erythema, scaling, moth-eaten alopecia, epidermal collarette, etc. Differentials can also be varied. Pyoderma can mimic dermatophytosis, demodicosis, pemphigus foliaceus, epitheliotropic lymphoma, etc. Check out this week's episode The Derm Vet podcast!
