Dog - Skin Fold Pyoderma

What is skin fold pyoderma?

Skin fold pyoderma (intertrigo) is one of the two major types of surface pyoderma (infection of the surface layers of the skin). The other major type is acute moist dermatitis.

Skin fold pyoderma is an inflammatory skin problem which occurs when skin surfaces are in contact. The skin fold allows the surface of the two adjacent areas to lie in close contact. This creates a warm, humid, poorly ventilated environment. The normal bacteria found on the skin then multiply, creating a surface infection in the fold.

Certain breeds appear to be predisposed to the condition. These include:

• Spaniels with lip fold pyoderma.
• Pekingese, Pugs and Bulldogs with facial fold pyoderma affecting the wrinkles on the face and nose.
• Shar Peis and also other loose skinned breeds if obese, can develop the condition within skin folds on the body, usually in the folds of the groin, the armpit (axilla) and also between pendulous mammary glands.

What are the signs?

These include moistness, exudation (oozing), redness and offensive odour. This occurs especially in Spaniels with lip fold problems.

Treatment

Mild cases respond well to medical treatment. The area has to be cleansed and sometimes the hair clipped. If the hair is clipped, care has to be taken that 'stubble' is not produced causing more damage to the opposing skin surfaces. Antibiotics, frequently combined with corticosteroids, are administered either topically in the form of ointment or by mouth or injection. If there is an initial response it is important that the area is cleansed and for this we supply appropriate disinfectant/antibacterial preparations. It is important a careful check is kept on the area for the first signs of any recurrence.

Chronic cases or cases that do not respond to medical treatment respond well to surgical removal of the skin folds. This frequently has to be carried out on affected Spaniels and flat faced breeds such as Pugs and Boxers.

Does the condition recur?

Recurrence is likely following medical treatment. Surgical removal of the fold obviously removes the cause and therefore the chances of recurrence.
