imbricate ringworm
Introduction
Introduction to the stacker Tineaimbricate, also known as vortex mites, is characterized by a specific concentric annular shape, such as vortex or tiling, hence the name. basic knowledge The proportion of illness: 0.026% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
The cause of ticks
(1) Causes of the disease
The pathogen of the disease is trichophyton concentricum, which is a bacterium.
(two) pathogenesis
The onset may be related to the susceptibility of the human race. The long-term close contact is not infected. The proper environment of the host skin is very important for the development of concentric bacteria. Except for the injury, the water content of the impregnated skin is also suitable for concentricity. The growth of sputum bacteria, air-impermeable clothing can increase the local temperature and humidity of the skin, interfere with the barrier function of the stratum corneum, initially skin color or small brown spots, gradually expanding into a ring shape, with grayish white scales on the surface, scaly central rupture Separation, adhesion of the outer edge, freeing of the inner edge of the centripetal.
Prevention
Dust prevention
The key to prevention is to actively treat the patient's original hand, athlete's foot, femoral hernia, hyperthyroidism, head lice, etc., and try to avoid close contact with other patients, including rickets such as cats and dogs. It is necessary to avoid indirect contact with the bathtubs, towels, etc. used by the patients, and to regularly clean and disinfect the public appliances, especially those in child care institutions and collective living.
Complication
Coma complication Complication
Different types of different systems can affect different systems. Endocrine gland dysfunction, hepatosplenomegaly, proteinuria or nephropathy, abnormal globulinemia, chronic glaucoma and giant tongue may occur.
Symptom
Symptoms of valvular sputum common symptoms itching skin red scaly ankle
More common in young men and young adults, children are rare, the skin lesions are skin-colored or brown spots, gradually expanding into a ring shape, with grayish white scales on the surface, scaly central rupture separation, outer edge adhesion, inner edge is centripetal free When the ring damage is formed, the center recurs a brown spot and expands into a ring. If it occurs repeatedly, the ring distance is about 2 mm. About 10 concentric circular scale rings can be formed at the original intrusion, forming a special multi-ring. Vortex-like or shingled appearance, the surrounding skin is brownish red, consciously itching, and the moss can be caused by scratching for a long time, the concentric round skin lesions may not be obvious.
The torso is more common in the trunk. It can be extended to the limbs, even the lips, the sulcus and the scalp. However, the palms are not tired and do not invade the hair. Unlike the hand and foot, the damage is symmetric.
The disease occurs, the relationship between development and season is not obvious, the course of disease is extremely slow, often unhealed for many years, and easy to relapse.
Examine
Check of stacking corrugated
The squamous fungus examination is easy to find most of the criss-crossed joint hyphae, and the typical concentric bacteria can be isolated during culture.
The pathological tissue showed chronic inflammation and no specificity. Unlike other dermatophytes, the tilapia not only invaded the stratum corneum of the epidermis, but also invaded the spinous layer, resulting in separation of the two layers.
Diagnosis
Diaphragm diagnosis
According to the special multi-circular and vortex-like lesions of this disease, most of the criss-crossed joint hyphae can be found in the squamous fungi examination. The typical concentric bacteria can be isolated during culture. The pathological tissues show chronic inflammation, no specificity, and other Different from dermatophytes, the tilapia not only invades the stratum corneum of the epidermis, but also invades the spinous layer, causing the two layers to separate and can be diagnosed.
1. Eczema hand and foot sputum sputum can be misdiagnosed as chronic eczema due to scratching or improper medication, but it is easy to be misdiagnosed as chronic eczema, but according to the edge of the lesion is clear, scattered scaly, typical damage in other parts, fungal microscopic positive can be identified .
2. Seborrheic dermatitis scalp, external ear, facial desquamation damage should be differentiated from seborrheic dermatitis, scaly squamous ridges, skin lesions scattered, fungal microscopy.
