Plain-English summary
A 4-year-old crossbred Welsh Mountain Pony gelding had several thick, round bumps on the inside of both ears, measuring between 3 to 8 mm. These bumps developed over a few months and did not affect the outer skin. A small tissue sample was taken for testing, which revealed that the pony had a condition called auricular chondrosis, a type of cartilage problem in the ear. This condition is unusual in horses, as it has mostly been seen in other animals like cats and dogs, as well as in humans.
Abstract
A 4-year-old crossbred, Welsh Mountain Pony gelding was presented with multiple, thick, round, raised, 3 to 8 mm diameter nodular lesions on the medial aspects of both ears. The nodules did not involve the epidermis and were observed to develop over several months. Punch biopsies were taken and histopathological examination returned a diagnosis of auricular chondrosis. Neither auricular chondrosis nor auricular chondritis has been reported in horses, although it has been recorded in cats, dogs, laboratory animals and humans.
