Parapsoriasis is a peculiar reaction pattern of the skin that appears to have a spectrum with small plaque parapsoriasis at one end and large plaque at the other. The spectrum between is bridged by pityriasis lichenoides, pityriasis lichenoides chronica, pityriasis lichenoides et varioliformis acuta, and lymphomatoid papulosis. The highlights of the clinical pattern of these diseases has been succinctly elucidated here to facilitate their recognition in day-to-day dermatologic practice. Their possible etiopathogenesis has been brought to focus in the light of changing concepts reported in the literature. Further, possible future implications demand a meticulous follow-up because, in a few cases, true neoplasms may ultimately develop. Treatment modalities are briefly discussed.

副银屑病是皮肤的一种特殊反应模式，它的范围似乎一端在小斑块型副银屑病，另一端在大斑块型副银屑病之间。这之间的范围由苔藓样糠疹、慢性苔藓样糠疹、急性痘疮样苔藓样糠疹和淋巴瘤样丘疹病所桥接。在这里，我们简洁阐明了该疾病最重要的部分，以方便人们在日常的皮肤病实践中鉴别他们。他们可能的发病机制被带入到集中在按照文献报道的变化的观念中。进一步讲，该疾病可能的未来影响需要一个细致的随访过程，因为在少数情况下，真正的肿瘤可能最后会形成。我们对该疾病的治疗方法进行了简要讨论。
