cellulitis
Introduction
Introduction Diffuse suppurative inflammation of subcutaneous tissue, subfascia, muscle space or deep connective tissue caused by staphylococcus or streptococcus. Inflammation can spread to the surrounding area, and if the treatment is timely and effective, the prognosis is good. Those with sepsis have a serious prognosis. Often occurs in the limbs or other parts, occurs in the fingers, praise, should be given a sufficient amount of antibiotics in a timely manner. Occurred in the neck, chest, can cause laryngeal edema, compression of the trachea, should be promptly rescued.
Cause
Cause
Cellulitis is an acute diffuse suppurative infection of subcutaneous, subfascial, intermuscular or deep loose connective tissue. Most of the pathogenic bacteria are hemolytic streptococcus, followed by Staphylococcus aureus, or anaerobic bacteria. The inflammation is not limited, and the spread is rapid, and the boundary with normal tissues is not obvious. It occurs mostly after skin and soft tissue damage, and can also occur directly from local suppurative infection or through lymphatic and blood flow.

Local redness, swelling, heat and pain are the first symptoms of all inflammation. Once the cellulitis is triggered, it will not only be so. There will be local burning sensation and tenderness, and there will be edema and erythema in the local area. At the same time, there will be fever, chills, general fatigue, headache or joint pain. When blood is examined, the white blood cells in the blood will rise significantly.
Diagnosis
Differential diagnosis
Mucosal proliferative inflammation: more obvious connective tissue, proliferation of blood vessels and epithelial cells, glandular cells and other parenchymal cells. Polyps can form in the mucosa.
Vascular allergic inflammation is one of the common vascular inflammations. Histopathological examination revealed fibrinous necrosis of the vessel wall and extensive neutrophil infiltration around the vessel. The onset can be urgent to slow down the common symptoms of the body including fever, fatigue and fatigue, local symptoms are mainly skin symptoms, a small number of patients have extra-skin involvement, such as joints, kidneys, lungs, digestive system.
Alveolitis: There are many common causes of organic dust such as actinomycetes and fungal spores, animal and plant proteins, bacteria and their products, insect antigens and certain chemicals. Typical changes in lung function were restrictive ventilatory disorders, forced vital capacity and total lung volume were reduced, and the 1 second rate was increased. Both carbon monoxide diffusion and lung compliance were reduced. Arterial oxygen saturation is reduced in severe and advanced patients. Pulmonary dysfunction in patients with chronic disease is mostly irreversible.
Local soft tissue infiltration, that is, the liquid slowly penetrates into the soft tissue, the human tissue is immersed in abnormal cells or the body cells that should not appear under normal conditions, and some diseased tissues spread to the surrounding. Excessive accumulation of substances in the cells or in the interstitium or accumulation of some of the original substances is also called infiltration. Some degeneration or deposition is also called infiltration.
Mosquito bites inflammation: This type of dermatitis occurs in summer and autumn. The rash often occurs in exposed parts of the body. The skin is characterized by local redness, edema, pimple, bleeding, and sometimes blisters or bullae. There are traces of biting. Conscious pruritus or itching, sometimes due to secondary infection, red line on the skin, indicating lymphatic inflammation, and sometimes local lymph nodes.
