Which of the following would be considered an abnormal finding on healthy canine external ear canal cytology?

Explanation:
In a healthy canine external ear canal, you’d expect to see normal debris, exfoliated epithelial cells, and cerumen. Malassezia is a yeast that can be a normal inhabitant, but it should not be present in large numbers in a healthy canal. When Malassezia is abundant on cytology, it indicates yeast overgrowth associated with otitis externa or an inflammatory state. So the abnormal finding in a healthy canal is the presence of Malassezia in significant numbers. The other components—cerumen, epithelial cells, and debris—are typical and not abnormal in this context.
