ReferencesContact dermatitis 是一种常见的皮肤病，接触某些物质后会出现红斑、瘙痒的斑块。它分为两种类型：刺激性接触性皮炎和过敏性接触性皮炎。刺激性接触性皮炎是因某些物质直接刺激皮肤而发生；过敏性接触性皮炎则是对接触皮肤的物质产生的迟发性反应。常见诱因包括毒葛、镍和香水。 症状通常表现为发红、脱皮、瘙痒，有时伴有水泡。急性病例可能较重，出现明显的红斑、起泡和肿胀；慢性病例则可能出现皮肤破裂、鳞屑等改变。 诊断主要依靠识别并避免致敏或刺激物。治疗方面，局部症状可使用类固醇霜；若病情广泛或严重，可口服类固醇。类固醇应在症状好转后逐渐减量，以防止反跳现象。
Contact dermatitis is a common skin condition that causes red, itchy patches after contact with certain substances. There are two types: irritant and allergic. Irritant contact dermatitis happens when something irritates the skin directly, while allergic contact dermatitis is a delayed reaction to a substance touching the skin. Common triggers include poison ivy, nickel, and fragrances. Symptoms typically include redness, scaling, itching, and sometimes blisters. Acute cases can be severe, with redness, blistering, and swelling, while chronic cases may involve cracked, scaly skin. Diagnosis usually involves identifying and avoiding the irritant. Treatment often includes steroid creams for localized reactions and oral steroids for widespread ones. However, steroids should be tapered off gradually to prevent a rebound reaction.

为治疗类似湿疹的皮疹的患者，医生需要了解导致该情况的所有可能原因。重要的是要考虑患者接触的物质是否会引起皮疹，尤其是在常规治疗后皮疹仍未消退的情况下。
The doctor treating a patient with a rash resembling eczema needs to know all the possible reasons for this condition. It's important to consider if something the patient is in contact with could be causing the rash, especially if it doesn't go away with usual treatment.

接触性皮炎（Contact dermatitis）是一种常见的皮肤病，由反复接触过敏原或刺激物引起，可表现为过敏性接触性皮炎或刺激性接触性皮炎。
Contact dermatitis is a frequent skin condition triggered by repeated exposure to substances that cause allergies or irritation, leading to either allergic contact dermatitis or irritant contact dermatitis.

接触性皮炎可由接触过敏原（过敏性接触性皮炎）或刺激物（刺激性接触性皮炎）引起，光毒性皮炎则是由光照导致的。
○ 体征和症状
接触性皮炎是因接触异物而出现的局部皮疹或皮肤刺激，通常需要数天至数周才能自行缓解。只有在皮肤不再接触过敏原或刺激物后，症状才会逐渐消退。
接触性皮炎分为三种类型：
（1）刺激性接触性皮炎
（2）过敏性接触性皮炎
（3）光接触性皮炎。刺激性皮炎通常局限于与致因直接接触的皮肤部位，而过敏性皮炎的范围可能更广。
过敏性接触性皮炎的常见致因包括：
Nickel, 14K or 18K gold, Chromium, Poison ivy (Toxicodendron radicans)
○ 斑贴测试
斑贴测试中最常见的三种过敏原是：
Nickel sulfate (19.0%), Myroxylon pereirae (Balsam of Peru, 11.9%), Fragrance mix (11.5%)
○ 治疗
避免使用肥皂和刺激性化妆品。防晒霜或其他化妆品可能导致面部反复干燥或瘙痒，尤其在女性中常见。若症状仅出现在阳光照射部位，应尽量减少日晒。
○ 治疗 – 非处方药
口服抗组胺药可缓解症状。西替利嗪或左西替利嗪的效果优于非索非那定，但可能引起嗜睡。
