After having reviewed the classical notions of normal skin innervation, the authors study the dermal amyelinic system in 12 patients suffering from psoriasis, using the cholinesterase method and the method of Bielchowski-Gross Jabonero. They successively describe the superficial network with the crooked isolated neurite rising to the tip of the papillae, the perivascular system which spreads out with the vessels themselves, and the hyperplastic perisudoriparous network with its peripilary endings. These findings clearly differ from those of Weddel. The amyelinic system appears to be little changed in psoriasis. The circumscribed nature of the morphological changes, however, should not deny it a role in the physiopathology of this dermatosis. A few recent hypotheses in this regard are discussed.
在回顾了正常皮肤神经支配的经典概念后，作者使用胆碱酯酶法和 Bielchowski - Gross Jabonero 法，对 12 例银屑病患者的真皮无髓鞘系统进行了研究。他们依次描述了浅表网络，其中弯曲的孤立神经突延伸至乳头尖端；血管周围系统，它与血管本身一起分布；以及增生的汗腺周围网络及其毛囊周围末梢。这些发现明显不同于 Weddel 的研究结果。在银屑病中，无髓鞘系统似乎变化不大。然而，形态学变化的局限性不应否定其在这种皮肤病生理病理学中的作用。文中讨论了这方面最近的一些假说。
