Autoeczematization, or id reaction, is a disseminated eczematous reaction that occurs due to a release of antigen(s) after exposure to a primary stimulus, with the eczema spreading to a site distant from the original one. This seemingly perplexing generalization most commonly is associated with stasis dermatitis or tinea pedis, though it may be caused by a wide variety of other disorders. We postulate that T cells are reactive to keratinocyte antigens that are produced during keratinocyte damage, which induce this autoeczematization. Studies with current technology are needed to facilitate further understanding of this phenomenon.
自身湿疹化，或同形反应，是一种播散性湿疹样反应，由于在初次刺激后释放抗原而发生，湿疹向远离原发部位的区域扩散。这种看似令人费解的普遍现象最常见于淤滞性皮炎或足癣，但它也可能由多种其他疾病引起。我们推测 T 细胞对细胞角质形成细胞抗原发生反应，这些抗原是在角质形成细胞损伤过程中产生的，诱导了这种自身湿疹化。需要使用现有技术进行研究，以促进对这种现象的进一步理解。
