TLDR Dermoscopy is useful for identifying skin lesions in dogs, with specific features distinguishing infundibular keratinising acanthomas from follicular cysts.
The study investigates the dermoscopic features of infundibular keratinising acanthomas (IKAs) and follicular cysts in dogs, using 35 lesions from 10 dogs. It highlights that white structureless areas are common in both IKAs (92%) and follicular cysts (66%). Unique to IKAs are surface keratin (76%), blood spots (38%), and four-dot clods (7%). Blood vessels were more frequently observed in IKAs compared to cysts. The study found near-perfect interobserver agreement for surface keratin and good agreement for other dermoscopic parameters. The findings suggest that dermoscopy is a valuable tool for assessing these skin conditions in dogs.
