skin boils
Introduction
Introduction It is an acute suppurative folliculitis and infection around the hair follicle, caused by staphylococcal invasion of hair follicles and sebaceous glands. From the beginning, it is a follicular inflammatory papule, which gradually enlarges, showing red hard nodules, pain and tenderness. After 2 to 3 days, the pus is broken and the pus, pus and necrotic tissue are discharged, and the crusting is cured within 1 to 2 weeks. Occasionally on the face, neck, arms, buttocks, patients may have symptoms such as fever, headache, and general discomfort. carbuncle The acute suppurative inflammation of most adjacent hair follicles, tissues around the hair follicles, and subcutaneous tissues is caused by the invasion of the hair follicles and sebaceous glands into the skin and spread to the periphery. Therefore, the area of the skin lesion is larger than that of the sputum, and the beginning is a purple-red lumps that are permeated and infiltrated. After purulent, multiple pustules appear in a honeycomb shape, including necrotic pus and bloody pus. Sometimes the necrotic tissue is completely detached, forming a deep ulcer, and leaving it behind. Occurs in the neck, back, shoulders, buttocks and thighs. The systemic symptoms of this disease are more obvious, and there are fever, headache, and loss of appetite at the beginning. There is pulsating pain in the affected part, and the local lymph nodes often enlarge.
Cause
Cause
Mainly Staphylococcus aureus. Normal hair follicles and their accompanying bacteria often exist, but only when local incentives or systemic resistance decline, bacteria begin to be active and cause inflammation. Local factors are mainly unclean skin, or facial damage caused by various reasons such as shaving can be an inducement; patients with systemic failure, consumptive diseases or diabetes are also prone to spasms.
(furuncle) is an acute suppurative infection of a single hair follicle and its surrounding tissues. The pathogen is mainly Staphylococcus aureus, and occasionally Staphylococcus epidermidis or other pathogens may cause disease. Infections occur in the head, neck, head, back hair follicles, buttocks, vulva and sebaceous glands.
Etiology and pathology
The occurrence of sputum is related to unclean skin, abrasions, high ambient temperature or reduced anti-infective capacity. Because the toxin of S. aureus contains coagulase, pustule formation is a feature of its infection.
The inflammation of the sputum is deep and large, and the local redness, swelling, heat and pain are obvious, and there is a pus in the center. According to clinical manifestations, the disease is easy to diagnose. If there is a systemic reaction such as fever, white blood cell count or blood routine examination should be performed. Patients with rickets should also check blood sugar and urine sugar for pus bacterial culture and drug sensitivity test.

At the beginning of the sputum, red, swollen, painful and indurated knots appeared on the skin, which became a cone-shaped bulge and tenderness. Then there was a yellow-white pus on the hard-topped top, surrounded by a red hard disk, and the patient felt itch, burning sensation and jumping pain. After the pus is ruptured, the pain is relieved after a little pus is removed, or a pus is formed at the top, separated from the surrounding tissue, and the inflammation gradually subsides, and the wound heals itself. In addition to the swelling of the lymph nodes in the drainage area, there is generally no obvious systemic symptoms. If improperly handled, such as random scratching or squeezing pus, hot compress, drug burning corrosion and improper incision, etc., can promote the spread of inflammation. The sputum located in the upper and lower lips and the nose is abruptly deteriorated due to its location in the dangerous triangle of the face. The local redness, swelling, and pain range is increased, accompanied by cellulitis or eruption into a sputum; even a sponge Sinus thrombophlebitis, sepsis or sepsis.
It occurs in the lips (lips), the upper lip is more than the lower lip, and more men than women. The extent of infection and the depth of tissue necrosis are both severe and severe pain. When acute inflammation and necrosis occur in most hair follicles, sebaceous glands and surrounding tissues, a rapidly expanding magenta inflammatory infiltrating mass can be formed. The infection can affect the subcutaneous fascia and muscle tissue. In the initial stage, the surrounding tissue is also necrotic. After the necrotic tissue is dissolved and discharged, most of the honeycomb cavity can be formed. Subsequently, the skin, mucous membranes or subcutaneous tissue between the cavities can also be necrotic, resulting in a purple-red color in the upper part of the lesion area; invasive edema around the deep and deep tissues.
The patients with cleft lip disease have difficulty eating due to extreme swelling, pain, and limited mouth opening. Local area lymph nodes enlarge, tenderness. Symptoms of systemic poisoning, such as chills, high fever, headache, loss of appetite, white blood cell count and neutrophil ratio increased. Lips are more likely to be associated with intracranial cavernous sinus phlebitis, sepsis, sepsis, and toxic shock and water-electrolyte disorders, resulting in higher mortality.
Diagnosis
Differential diagnosis
Should pay attention to the identification of facial acne , head lice , cellulitis and so on.
Facial acne: mostly in the lips, nose, eyebrows, sputum, etc., the local beginning is a pus, the lumps are hard and deep, such as the shape of nails, or hemp or itching. Following the redness and hyperplasia, it can develop into several pus heads, burning pain.
There are head lice: also between the skin, there is a miliary pus in the beginning, easy to spread to the surrounding rot.
Cellulitis: purulent inflammation for a wide range of skin and subcutaneous tissues. Suppur occurs in subcutaneous or deep loose tissues (this tissue is called cellulite because of its structure like a honeycomb), called cellulitis. The local manifestations are diffuse redness, unclear state, significant pain, and systemic symptoms such as aversion to cold and fever. After the pus, it ulcerates and forms an ulcer, which is cured after about 2 weeks. There are also those who do not break, and the inflammatory infiltration naturally absorbs and subsides.
