Miscellaneous.

The research article discusses unique clinical conditions in horses that are not classified under standard categories and specifically explores aural plaques, photosensitivity-related skin conditions, pastern leukocytoclastic vasculitis and a foot ailment called ‘grease heel’.

Aural Plaques

In the study:

• The aural plaques, also known as auricular papillomas, are commonly seen in horses and are unusual ear lesions.
• The researchers provide the clinical description, cause (aetiology), and tissue-level (histopathologic) findings for these lesions.

Photosensitivity-related Dermatoses

The research further investigates:

• Skin conditions (dermatoses) that are either worsened by or caused by exposure to sunlight (photosensitivity).
• The discussion of these conditions covers their causes (aetiology), the process of disease development (pathogenesis), and clinical features.

Pastern Leukocytoclastic Vasculitis

The paper also examines:

• Pastern leukocytoclastic vasculitis, a skin condition affecting the lower legs of horses.
• The authors suggest that photosensitivity could play a part in the development of the lesions seen in this condition.

Grease Heel

Lastly, the research delves into:

• The different causes of ‘grease heel’, a non-specific term for a chronic and often painful condition in horses’ feet, also known as scratches or mud fever.
• Extensive discussion is provided to understand the underlying causes and development of this condition.
