299. The many faces of pyoderma

from The Derm Vet Podcast Hosted by Ashley Bourgeois, DVM, Dip ACVD

Send me a derm question or story through text or voicemail! 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! Also, I highly encourage you to check out the YouTube channel to see some clinical images. 00:00 – Intro 01:20 – Moth-Eaten Alopecia 03:18 – Diffuse Alopecia 04:21 – Erythema 05:27 – Scaling 06:40 – Epidermal Collarettes 07:57 – Crusting 11:15 – Urticaria-like Lesions 13:58 – Outro
