Exudative discoid lichenoid dermatitis

Introduction of exudative discoid mossy dermatitis Exudative discoid dermatitis (exudativediscoidandlichenoiddermatitis), also known as Oid-Oid disease, was also known as Sulzderger-Garde syndrome because Sul-zdergre and Garde first reported the disease in 1937. The disease is characterized by exudative discoid damage, lichen-like damage, invasive damage, wheal damage, etc., which are characterized by hyperthermia and chronic rare skin diseases, which are more common in men aged 40-60 years, especially those with nervousness. But it can also happen to women and children. Whether the disease is an independent disease is still controversial. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: edema

Etiology of exudative discoid dermatitis

Cause:

The cause is still unclear. In recent years, it has been thought to be related to mental factors and autoalgesia. Some people think that the disease is a special type of neurodermatitis.

Pathogenesis

The pathogenesis is still not very clear.

Exudative discoid mossy dermatitis prevention

1. Remove possible pathogenic factors, such as neurasthenia symptoms, should be actively treated.

2. Early diagnosis, early treatment.

Exudative discoid mossy dermatitis complications Complications edema

Local lymphadenopathy, edema.

Exudative discoid mossy dermatitis symptoms Common symptoms Wind unity itchy papulitis granuloma edema

Mainly manifested in the following damages:

1. Exudative disc-shaped lesions : skin lesions often occur suddenly, lasting for a short period of time, often rapidly disappearing or transforming into moss-like, invasive lesions, widely distributed, occurring in the scrotum, penis, extremities, upper chest, The shoulders and ankles, etc., the face (especially the bridge of the nose), the armpits and the abdomen can also be affected. The lesions are oval-shaped discoids of various sizes, several millimeters or centimeters in diameter, with clear boundaries and ridges. The exudate, crusting, and disc-like damage of the trunk are consistent with the skin texture, and it is consciously itchy and cool or burning.

2. Mossy-like damage : Skin lesions last the longest in four typical lesions and can last for several years, especially with the longest lesion in the penis, which is characterized by systemic dryness, hair follicles and non-follicular goose bumps. And mossy patches.

3. Invasive damage: multi-line exudative discoid lesions are transformed, manifested as infiltrative edema lesions, often accompanied by local lymphadenopathy, clinically similar to mycosis fungoides and other types of reticuloma Ill, consciously itchy, especially at night.

4. Wind group : About half of the cases may be associated with mossy discoid lesions. The characteristics of the wind group are small and deep, which is more persistent than general urticaria.

Examination of exudative discoid mossy dermatitis

Eosinophils in the blood are often increased, and the classification can reach 0.06 to 0.30.

Diagnosis and differentiation of exudative discoid mossy dermatitis

According to the disease, it occurs in middle-aged men with neuroticism. The typical clinical damage and pathological changes are infiltration of plasma cells around the dermal arterioles, which can establish a diagnosis.

However, in the exudation period, it is necessary to distinguish between contact dermatitis, coin-shaped eczema and exudative neurodermatitis, and exclude lichen planus and mycosis fungoides in the moss-like and invasive stages.
