Chronic Progressive Lymphoedema

Welcome to the world’s first comprehensive guide to CPL for owners, veterinary professionals and complimentary therapists in the equine industry.

What is CPL?

Early (score AA) CPL.
Severe (score C) CPL
Vitus the Brabant
CPL Nodules – round, flat and clearly demarcated.
Not to be confused with Chronic Proliferative/verrucous Pastern Dermatitis.
Often this fold is the first indication of CPL.

“C.bovis infestation may affect the progression of chronic pastern dermatitis (also known as chronic proliferative pastern dermatitis, chronic progressive lymphoedema and dermatitis verrucosa) in draft horses, manifesting with oedema, lichenification and excessive skin folds that can progress to verruciform lesions.”

Is this CPL?

Creasing like this can be prevented to some degree by applying an emollient regularly and using something like Sebolytic® shampoo to remove the keratin build up and restore the natural balance of the skin.

This example has also been affected by MASD (moisture associated skin damage) prior to clipping.
An example of the same scenario but further advanced in this case, note the puffiness to the area around the ergot and directly above and below the deep crease. These horses will likely benefit from CPL management protocol because they now have insufficiency in the superficial lymphatic drainage.
“Mallenders” – hyperkeratosis behind the knees.
Hyperkeratosis is simply an excess production of keratin which presents as crusty build up and flaky skin but can cause scarring and become infected.
