What causes erythema annula

Considering that jock itch is more likely to be caused by fungal infection, it is recommended to use antifungal drugs**, such as ketoconazole ointment**, which does not rule out the possibility of annular erythema, which is mostly caused by abnormalities of the immune system.

Erythema annulas**The symptoms are caused by multiple factors, such as immune factors, infection factors, etc., which are induced by external or internal factors, and it is recommended to be diagnosed and accepted in a regular hospital**.

Analysis: Erythema annulus is a symptom of rheumatic fever**. The common causes are: 1. Rheumatic erythema annula 2. Erythema annula centrifuga.

It is a ring-shaped, centrifugal erythema** disease observed under the microscope It is an exudative lesion, the superficial dermis is vasodilated and congested, the perivascular tissue is edema, and the inflammatory cells are infiltrated. It usually disappears within 1-2 days.

Analysis: Erythema annulus is a symptom of rheumatic fever**. Common reasons are:

Rheumatic erythema annulais is less common and appears as pale erythema with distinct annular or semi-annular borders, varying in size. The center is pale, appears on the trunk and proximal extremities, is transient, or may be extinct and prolonged, and may appear for several weeks.

Suggestions: It is often accompanied by fever, migratory arthralgia, rapid erythrocyte sedimentation rate, anti-chain "O" positive and other manifestations of rheumatic fever. Centrifugal annular erythema is a ring-shaped, centrifugal erythema** disease.

How to do erythema annulae**Answerer: The main cause of HYDC disease may be related to allergies, drugs, infections and other factors, it is recommended to go to the hospital for routine blood tests to see if it is caused by infection Oral cetirizine or loratadine, oral Kunming begonia, oral prednisone, topical elosolone or euzol; If the test results indicate that there is an infection, you can add antibiotics orally, such as azithromycin, this disease is easy to recur, you need to adhere to **, and you need to pay attention to the diet, eat less fish, shrimp, milk and other foods with high protein content.

In severe cases, corticosteroids are given, etc.**. At the same time, care should be taken to control the infection. If it is caused by hot and humid weather, it is red and itchy acne on the legs or hands.

In acute attacks, bed rest should be taken and strenuous exercise should be avoided. Proceed for. The drug causing the drug is discontinued. Antifungal treatment for fungal infections**. Excessive itching can be washed with topical calamine mixture.

1.Erythema uncomplicated gyriformis.

**Procaine, vitamin C, high-dose vitamin C or intravenous infusion of Danshen injection, as well as antihistamines and calcium, can be given.

2.Centrifugal annul erythema.

In severe cases, glucocorticoids, antihistamines, acedapsone (dapsone), chloroquine, topical glucocorticoids, or mild antipruritics may be tried. At the same time, care should be taken to control the infection.

3.Creeping gyrus erythema.

**A detailed examination should be carried out to look for concomitant tumors and perform**. After a general tumor**, the lesions disappear. Antihistamines may be taken by mouth.

4.Rheumatic erythema annula.

** The principle is early diagnosis and early and appropriate combination of drugs to control rheumatic activity. Commonly used anti-rheumatic drugs include neproxen, aspirin, ibuprofen, glucocorticoids, immunosuppressants, etc. Supplemented with symptomatic**.

Erythema annula, also known as erythema annula, refers to the general term for the appearance of erythema annularis lesions on the **. Erythema annula is not a stand-alone disease, but refers to a dermal inflammatory response caused by various causes, such as vasodilation, hyperemia, and cellular infiltration. Usually includes conditions such as erythema simplex gyrus, erythema centrifugal annula, erythema creeping gyrus, erythema migratory chronic, and erythema marginal rheumaticus.

There are two common types of erythema in clinical practice: simple ileomorphous erythema (vascular neurogenic erythema annulae) and rheumatic erythema annula (erythema ruminum rheumaticus). For allergic symptoms such as itching.

The disease** is unknown, but studies suggest that progesterone or chorionic puncture during pregnancy, gestational hypertension, and low birth weight may be associated with the development of hemangiomas.

Erythema annulais is a symptom of rheumatic fever**. Common reasons are:

1. Rheumatic annular erythema.

Less commonly, pale erythema with a ring or semi-annular border with distinct borders, varying in size. The center is pale, appears on the trunk and proximal extremities, is transient, or sometimes extended, and may appear for several weeks. It is often accompanied by rheumatic fever manifestations such as fever, migratory arthralgia, increased erythrocyte sedimentation rate, and positive anti-chain "O".

2. Centrifugal annular erythema is a ring-shaped, centrifugal erythema ** disease, and the clinical characteristics are:

1) The majority of patients are young and middle-aged, more females than males, and the onset is seasonal, and it is more common in summer;

2) It is more likely to occur in the limbs, trunk, dorsum of hands and feet, etc.;

3) one or more annular lesions, with reddening at the edges, slightly raised, lightly itchy or asymptomatic; The rash may resolve in 1-2 weeks, but is often reversed and lasts for several cavities or years.

4) Some patients have rheumatic fever manifestations such as arthralgia, sore throat, and anti-chain "O" positive.

a). Erythema uncomplicated gyruformis: Procaine vitamin C, high-dose vitamin C or salvia injection can be given intravenously, and antihistamines.

Erythema annulais centrifugation: Glucocorticoids, antihistamines, acedapsone (dapsone), chloroquine, topical glucocorticoids, or mild antipruritics.

Creeping erythema gyrus: **should be carefully examined for concomitant tumors and performed**. After a general tumor**, the lesions disappear. Antihistamines may be given for oral use.

ii) Prognosis. Simple ileomorphous erythema, sometimes delayed for months. Erythemaannulase centrifugum is chronic and can last for months or years.

Pigmentation remains after subsidence. Except for a few patients with cancer, the prognosis is generally good. Creeping erythemagyratumrepens, the course and prognosis of this disease are related to the nature and degree of malignancy of the accompanying tumor.
