There is a circle-shaped skin disease on the body

Circle-shaped skin diseases on the body are likely caused by fungal infections, pityriasis rosea, urticaria, seborrheic dermatitis and other factors. You should go to a professional medical institution's dermatology department as soon as possible for a detailed examination and treatment based on the cause of the disease.

1. Fungal infection: When the skin is infected by fungi, it may cause obvious circles on the skin, accompanied by itching and burning sensations. It can be checked through dermatoscopy. For fungal infection, apply antifungal ointment under the guidance of a doctor.

2. Pityriasis rosea: Pityriasis rosea is also a common skin disease. It may cause many circles on the skin and redness on the skin surface. For factors such as pityriasis rosea, applying anti-inflammatory ointment under the guidance of a doctor can reduce the irritation of inflammation.

3. Urticaria: When an allergic reaction occurs on the skin, it is likely to cause obvious urticaria to form on the skin, accompanied by itching. The factors of urticaria can be treated strictly according to the doctor's instructions, through external anti-allergic drugs, or through oral antihistamines.

4. Seborrheic dermatitis: Seborrheic dermatitis on the skin may also cause inflammatory reactions on the skin, which mainly appear as circles on the skin and can be treated by applying external anti-inflammatory ointments.
