Erysipelas is an acute inflammation of the skin and reticular lymphatic vessels. The onset of erysipelas is due to hemolytic streptococci invading the skin and mucosal reticular lymphatic vessels through small wounds in the skin mucosa. Erysipelas commonly occurs on the lower limbs and face, progressing rather quickly, with seldom tissue necrosis, and a tendency for recurrent episodes. The local symptoms include patchy erythema, bright red color, lighter in the center, with clear and slightly raised edges.

What is the cause of erysipelas infection?

Erysipelas is a superficial lymphatic infection induced by Group A beta-hemolytic streptococcus infection, often entering through breaks in the skin or mucous membranes. Athlete's foot and dermatitis are often the main causes of erysipelas on the lower legs and face. Malnutrition, excessive drinking, and scratching can also trigger the disease. Clinically, erysipelas manifests as well-demarcated edematous bright red patches on the lower legs or face, with a tense and shiny surface that can even form blisters. The local skin temperature is elevated, and there is tenderness and pressure pain, often accompanied by fever, a burning pain sensation, and nearby lymph nodes may be enlarged.

What should erysipelas patients pay attention to in their diet?

Patients with erysipelas need to pay special attention to their diet during illness, as their body's resistance and immunity are relatively low. It is advised that they eat more green vegetables and fruits, such as leafy greens, carrots, apples, pears, and grapes, and avoid spicy and irritating foods such as barbecue, spicy hot pot, onions, ginger, and garlic.

Erysipelas is caused by what?

The fundamental cause of erysipelas is mainly due to a streptococcal infection of the lymphatic vessels, causing acute non-purulent inflammation. Patients with erysipelas often may have underlying conditions such as athlete's foot, ulcers, or other infectious foci. Erysipelas is prone to develop secondary to ulcers, trauma, or some purulent infections, spreading directly from these primary diseases through the skin, mucous membranes, lymphatic channels, or hematogenous invasion.

What is the best medicine for erysipelas?

Erysipelas is an infectious disease that commonly affects the lower legs and face. Once erysipelas is diagnosed, penicillin is the recommended treatment. However, if there is an allergy to penicillin, cephalosporins or quinolones can be used as alternatives. Generally, intravenous infusion is necessary; oral administration alone is not effective. Intravenous medication is required to achieve the best anti-inflammatory treatment results.
