汗泡疹。可以短期使用激素治疗
汗泡疹是发生于手部或足部的湿疹性变化(过敏性皮肤炎变化),
发生时病人的两侧手掌、脚掌或手指、脚趾侧面常有剧痒, 并可见许多细小的、散布性或集蔟的水泡, 有的水泡是呈现淡红色丘疹状。这些水泡有的在数小时内急速发生, 而大多是在数天中陆续增加,有时集蔟的水泡会合成大的水泡, 而使病人无法使用手做事或脚走路。 这些水泡有时会并发细菌性感染,而有化脓反应。 这些急性期水泡经过治疗后会很快缓解,但仍会复发。 通常水泡不会破开,会自然吸收而乾涸,一、 两周后水泡会剥离成类圆形的乾皮屑轮, 皮肤呈现乾燥脱皮龟裂的现象而有疼痛感,然后会恢复成正常皮肤。 「汗泡疹」好发在青年男女及中年早期(20-40岁), 大部分病人合并有多汗症, 但是此病并非由汗管阻塞或汗管膨大成水泡而来。 每年夏季或季节交替时易发作,每次持续3-4周。 有的病人则变成慢性。部分病人有异位性体质或镍过敏。 避免过敏原可改善症状,但不能完全根除。有的病人在情绪压力、 熬夜时会恶化。真正的病因目前则未知。
至今,尚未断根。
IN ENGLISH IT IS CALL--Pompholyx, is a common type of eczema affecting the hands and sometimes the feet.
The first stage of this condition is the appearance of tiny blisters that are deep in the skin. Some people describe them as "tapioca-like" blisters. These blisters contain a clear water-like substance (edema fluid) that usually subsides without bursting and expelling its contents. The blisters are associated with an itching and sometimes a burning sensation. In extreme cases, peeling, cracking and crusting of the skin can occur. The skin may also harden.
Pompholyx is also known as dyshidrotic eczema or vesicular eczema of the hands and/or feet. The severity of the condition can range from a few dry, red, itchy patches to huge areas of the body which can be covered in sore, inflamed, weeping and bleeding skin which can invariably become infected. It most commonly however just affects the hands and feet.
It can start on the sides of the fingers as itchy little bumps and then can develop into a rash. The condition can also affect only the feet. Some patients are affected in both the hands and feet.
Episodes usually occur abruptly. The blisters are extremely itchy and usually appear in crops and last for one or two weeks. As the swelling and blisters subside scaling and fissures can occur. The course tends to be unpredictable.
