Chronic papillary ulcerative pyoderma

Introduction to chronic papillary ulcerative pyoderma Chronic papillary ulcerative pyoderma (pyodermachronicapapillarisetexulcerans) is a chronic infectious skin disease characterized by papillary or sputum hyperplasia and fistula ulcers. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: lymphitis

Causes of chronic papillary ulcerative pyoderma

(1) Causes of the disease

Mainly caused by Staphylococcus aureus, can also be isolated from Escherichia coli, Proteus and other diplococcus, often occurs in mild trauma, insect bites, scratching, pyoderma and eczema, the body's immune function is low and malnutrition is Its incentives.

(two) pathogenesis

After mild trauma, insect bites, scratching, pyoderma and eczema, when the body's immune function is low and malnutrition, Staphylococcus aureus, Escherichia coli, Proteus and other diplococcus invade the skin, leading to inflammatory reactions and suppuration , the formation of edematous plaque, plaque ulceration, ulceration, verrucous or papillary hyperplasia.

Prevention of chronic papillary ulcerative pyoderma

1. In the units prone to pyoderma (such as some factories, agricultural machinery stations, primary schools, etc.), extensive publicity and education on the prevention and treatment of suppurative skin diseases, regular preventive inspections, as far as possible to eliminate all factors.

2. Pay attention to skin hygiene, strengthen physical exercise and increase skin resistance.

3. Maintain the integrity of skin function. For skin diseases, especially pruritic skin diseases, timely treatment should be carried out to prevent skin damage and avoid irritation such as scratching and skin friction.

4. Clothes, towels, basins, etc. are prohibited from public use to prevent contact with infection. The patient should be properly isolated. The dressings and contact materials used by the patient should be strictly disinfected or burned. During the illness, it is forbidden to use the liquid to clean the skin lesions. Wash the affected area with tap water to prevent extension.

5. When you are sick, you should ban alcohol or spicy food, and eat less food.

Chronic papillary ulcerative pyoderma complications Complications

The disease belongs to the bacterial infection of the skin, so it often complicated with lymphangitis, lymphadenitis, and even acute glomerulonephritis. For patients with lymphadenitis, "firewire"-like skin lesions may occur, often with tenderness, and lymphangiogenic changes may occur in severe cases. Patients with lymphadenitis often have swollen lymph nodes, pain, and purulent secretions. Patients with glomerulonephritis often have abnormal renal function.

Symptoms of chronic papillary ulcerative pyoderma Common symptoms sputum purulent secretion papule pustule

Initially a miliary size follicular papules or pustules, gradually increased, merged into a purple-red edematous plaque, plaque ulceration, ulceration, verrucous or papillary hyperplasia, the edge of the ulcer is piercing, cyan, the surface has Purulent secretions and scars can develop in a sinus manner, sometimes forming a sinus. After pressurization, the pus flows out from the other end of the sinus. Local tenderness and tenderness occur in the limbs, especially in the back of the hand, but the jaw The torso can also occur, and there may be local lymphadenopathy, more common in middle-aged farmers, chronic menstruation, prolonged course of disease, often repeated attacks, until the majority of the body is invaded, leaving scars.

Examination of chronic papillary ulcerative pyoderma

Clinical skin examination: initial miliary size follicular papules or pustules, gradually increased, fused into purple-red edematous plaques, plaque ulceration, ulceration, verrucous or papillary hyperplasia. The edge of the ulcer is perforated, blue-red, with purulent secretions and scars on the surface. It can develop limp, sometimes forming a sinus. After pressurization, the pus flows out from the other end of the sinus, and there is local tenderness.

Other tests: blood routine, C-reactive protein, ESR.

Diagnosis and diagnosis of chronic papillary ulcerative pyoderma

diagnosis

Diagnosis can be performed based on clinical performance and laboratory tests.

Differential diagnosis

However, it should be differentiated from verrucous skin tuberculosis, proliferative pyoderma and coloring fungal diseases.

Sickle skin tuberculosis: the surface of the lesion is sputum-like proliferation, usually with small abscess, surrounded by brown-red infiltration, no ulceration, lack of self-conscious symptoms, tuberculin test positive, histopathological examination can find acid-fast bacilli.
