Auricular Perichondritis and Multifocal Chondromata in an Egyptian Donkey with Droopy

A 9-years-old female Egyptian donkey presented with ear drooping, multiple subcutaneous firm nodules (3-7 mm) on the medial surfaces of both ears and intact skin. Furthermore, the ear pinnae were diffusely thickened with subcutaneous induration. The cartilaginous plates of the ear pinnae were intact...
