Published on Jan View 3 Download 0. For the dimpled appearance of skin, see cellulite. Cellulitis can be caused by normal skin flora or by exogenous bacteria, and often occurs where the skin has previously been broken: Skin on the face or lower legs is most commonly affected by this infection, though cellulitis can occur on any part of the body.

Predisposing conditions for cellulitis include insect or spider bite, blistering, animal bite, tattoos, pruritic itchy skin rash, recent surgery, athlete’s foot, dry skin, eczema, injecting drugs especially subcutaneous or intramuscular injection or where an attempted IV injection “misses” or blows the veinpregnancy, diabetes and obesity, which can affect circulation, as well as burns and boils, though there is debate as to whether minor foot lesions contribute.
Occurrences of cellulitis may also be associated with the rare condition hidradenitis suppurativa. The photos shown here of cellulitis are of mild cases, and are not representative of earlier stages of the disease. The appearance of the skin will assist a doctor in determining a diagnosis. A doctor may also suggest blood tests, a wound culture or other tests to help rule out a blood clot deep in the veins of the legs.
Cellulitis in the lower leg is characterized by signs and symptoms similar to those of a deep vein thrombosis, such as warmth, pain and swelling inflammation. This reddened skin or rash may signal a deeper, more serious infection of the inner layers of skin. Once below the skin, the bacteria can spread rapidly, entering the lymph nodes and the bloodstream and spreading throughout the body.
This can result in influenza- like symptoms with a high temperature and sweating or feeling very cold with shaking, as the sufferer cannot get warm. In rare cases, the infection can spread to the deep layer of tissue called the fascial lining. Necrotizing fasciitis, also called by the media “flesh-eating bacteria”, is an example of a deep-layer infection.

Chickenpox and shingles often result in blisters that break open, providing a gap in the skin through which bacteria can enter. Diseases that affect blood circulation in the legs and feet, such as chronic venous insufficiency and varicose veins, are also risk factors for cellulitis.

Because the characteristic bullseye rash does not always appear in patients infected with Lyme disease, the similar set of symptoms may be misdiagnosed as cellulitis.
Standard treatments for cellulitis are not sufficient for curing Lyme disease. The only way to rule out Lyme disease is with a blood test, which is recommended during warm months in areas where the disease is endemic. Pain relief is also often prescribed, but excessive pain should always be investigated as it is a symptom of necrotising fasciitis.
As in other maladies characterized by wounds or tissue destruction, hyperbaric oxygen treatment can be a valuable adjunctive therapy, but is not widely available. The horse will exhibit inflammatory edema, which is marked by hot, painful swelling.
This swelling differs from stocking up in that the horse will not display symmetrical swelling in two or four legs, but in only one leg. This swelling begins near the source of infection, but will eventually continue down the leg. In some cases, the swelling will also travel upward. Treatment includes cleaning the wound and caring for it properly, the administration of NSAIDs, such as phenylbutazone, cold hosing, applying a sweat wrap or a poultice, and mild exercise.
