**Differential Diagnosis of Erysipelas**
Erysipelas is an acute inflammation of the skin's reticular lymphatics and superficial subcutaneous tissue caused by streptococcal infection. It commonly occurs on the lower legs, followed by the head and face. Diagnosing erysipelas is not difficult; it can be diagnosed based on the condition, clinical manifestations, and auxiliary examinations. Below, we will introduce the differential diagnosis of erysipelas, which refers to diseases that are easily confused with erysipelas.
1. **Drug-induced Dermatitis**
- There is a history of medication use. The face may show redness and swelling, with the eyes partially closed due to swelling. However, the boundaries are unclear, and there are no systemic symptoms such as chills or fever.
2. **Paint-induced Dermatitis**
- There is a history of exposure to paint. The lesions have unclear borders, with significant redness, swelling, and warmth, sometimes accompanied by small blisters. There is no pain or systemic symptoms like fever.
3. **Pseudoerysipelas**
- Often occurs on the hands and is related to occupation. The affected area is small, with a slow onset and no obvious systemic symptoms.
4. **Cellulitis**
- The skin appears dark red, with central elevation and significant redness and swelling, but milder inflammation at the edges. The borders are unclear, and the area feels slightly hard and firm. In contrast, erysipelas has elevated edges, obvious inflammation, and clear borders.
