Auricular chondrosis in a horse.

This research investigates a case of auricular chondrosis, a condition previously unreported in horses, which was discovered in a 4-year-old crossbred Welsh Mountain Pony gelding.

Case Overview

• The subject of the study was a 4-year-old crossbred Welsh Mountain Pony gelding.
• It presented with multiple nodular lesions on the medial aspects of both ears that did not involve the epidermis, and showed development over several months.

Diagnostic Process

• Punch biopsies were taken from the affected area for analysis.
• The samples were examined histopathologically, a process that involves the microscopic examination of tissue in order to study the manifestations of disease.

Results and Findings

• The result of the histopathological examination led to a diagnosis of auricular chondrosis, which is a condition characterized by abnormal cartilage formation or growth in the ear.
• This diagnosis is noteworthy because, prior to this research, auricular chondrosis hadn’t been reported in horses.

Comparisons With Other Species

• The condition auricular chondrosis is known to occur in other species such as cats, dogs, laboratory animals and humans.
• The occurrence of this condition in a horse adds a new species to the list of animals that can potentially be affected by auricular chondrosis.
