A brief analysis of vasculitis erythema nodosum

In recent years, the probability and frequency of vasculitis erythema nodosum have been on the rise, so it has been classified as a Class I disease, hoping to attract the attention of medical institutions and people. Because its onset is relatively complicated, it can be an independent symptom, or it may be a manifestation of one of the systemic diseases on the skin. The following is an analysis of its symptoms and misunderstandings in the treatment process:

Erythema nodosum is an allergic vasculitis caused by increased permeability of the venous walls in the deep dermis or subcutaneous tissue. It is characterized by subcutaneous nodular erythema that occurs mainly on the limbs, especially the lower limbs. The subcutaneous nodules are usually distributed on the inner side of the calves below the knees of both lower limbs. They can also invade the outer side of the calves or the feet, thighs above the knees, and even the upper limbs. They are rare on the head and face. It manifests as bilateral symmetrical bright red, dark red, or purple-red nodular lesions on the limbs, with obvious tenderness, tingling, distending pain, or burning sensation, generally without itching.

This disease is more common in young women. Some patients with systemic diseases (such as Behcet's disease, Crohn's disease, ulcerative colitis, adult Still's disease, lupus erythematosus, sarcoidosis, etc.) often have skin lesions with clinical symptoms of erythema nodosum-like rash. The disease can occur all year round, with a higher incidence in spring and autumn, and has been on the rise in recent years.

Currently, patients with erythema nodosum have more or less the following misunderstandings during the treatment process: When the patient first develops the disease, they do not have a comprehensive understanding of erythema nodosum and are not clear about the cause of the disease. Western medicine takes effect quickly and cures quickly. In cases of bitterness and trouble, antibiotics and hormones are used for treatment. When the disease is controlled by antibiotics and hormones, it is considered cured. After stopping the treatment, the disease relapses or even rebounds and worsens. The patient seeks medical advice everywhere and abuses antibiotics and hormones in large quantities, causing a vicious cycle, relapse, and rebound and worsening of the disease. The patient then believes that erythema nodosum is an incurable disease that cannot be completely cured, and loses confidence in treatment. This is an unscientific and wrong understanding.

From the above introduction to the disease of erythema nodosum of vasculitis and the problems existing in its treatment, such as not taking the dosage of medicine according to the doctor's requirements, stopping the medicine when the symptoms disappear, and not completely eliminating the root cause of the disease, it is often easy to have repeated rebounds. In addition, due to the low medical level in some places, it is impossible to diagnose the cause of the disease, and incorrect treatment plan also affects recovery.
