Infectious eczematoid dermatitis (IED) is characterized by an acute eczematous eruption triggered by purulent discharge from a primary infected site. Alcohol consumption, cigarette smoking and occupations with higher incidences of contact dermatitis portend increased risk for IED. Staphylococcus aureus is the most commonly cultured microbe from affected skin, with Streptococcus species the second most. Patients are first evident with peripherally spreading vesicles and pustules radiating from an infected site. Older areas of involvement become crusty, scaly and erythematous. Diagnosis is clinical. Other eczematous rashes, including autoeczemitization and contact dermatitis, should be on the differential diagnosis list. The treatment centres on topical antibiotics and soaks. Prognosis has improved since the advent of antibiotics. However, cases with multiple relapses and poor response to therapy are still observed.
感染性湿疹样皮炎（IED）的特征是由原发性感染部位的脓性分泌物引发的急性湿疹样皮疹。饮酒、吸烟以及接触性皮炎发病率较高的职业预示着患IED的风险增加。金黄色葡萄球菌是受影响皮肤培养出的最常见微生物，链球菌属次之。患者最初表现为从感染部位向外扩散的水疱和脓疱。较老的受累区域会结痂、脱屑并出现红斑。诊断依靠临床症状。其他湿疹样皮疹，包括自体湿疹化和接触性皮炎，应列入鉴别诊断清单。治疗以局部使用抗生素和湿敷为主。自抗生素问世以来，预后有所改善。然而，仍有多次复发且对治疗反应不佳的病例。
