Ceruminous cystadenomatosis may sound like a rare and complicated diagnosis, but for veterinary dermatologists, these purple “blueberry-like” cysts in the ear canal are a frustratingly common challenge for breeds like Persian cats or Cocker Spaniels. While the condition is technically benign, it can cause significant pain, chronic infections, and quality-of-life issues for pets. In this episode, Dr. Brittany Lancellotti and Dr. Austin Richman explain what ceruminous cystadenomatosis is, why it happens, how allergies may play a role and how modern treatments like CO₂ laser therapy and video otoscopy can bring relief.
