Pityriasis rosea - 玫瑰糠疹
玫瑰糠疹 (Pityriasis rosea) 背部 ― 无症状的斑疹和斑块，与通常会发痒的药疹不同。
如果很痒，您可能怀疑患有过敏性疾病，例如nummular eczema。

Pityriasis rosea 是一种暂时性皮肤病，表现为凸起的斑块和鳞片。它通常以一个补丁开始，称为 herald patch ，然后在接下来的几周内出现更多补丁。然而，并非所有玫瑰糠疹患者都会出现这种初始斑块。这些斑块通常在树干和上肢上形成类似于圣诞树的独特图案。
Pityriasis rosea, also known as pityriasis circinata, roseola annulata, and herpes tonsurans maculosus is an acute self-limiting papulosquamous disorder. It is often characterized by an initial herald patch, followed by scaly oval patches within 2 weeks. However, the herald patch is not always present. The scaly oval patches typically distribute in a Christmas-tree pattern on the trunk and proximal extremities. This activity reviews the evaluation and treatment of pityriasis rosea and the importance of the interprofessional team in recognizing and managing patients with this condition.

Pityriasis rosea 是一种常见的皮疹，通常从躯干上的单个斑块开始，然后扩散到覆盖躯干和四肢。诊断依赖于临床检查。最初的补丁呈红色，边框凸起，中心凹陷。皮疹通常在大约两周后出现。患者可能会出现疲劳、恶心、头痛、关节疼痛、淋巴结肿大、发烧和喉咙痛以及皮疹。类似的病症包括梅毒、脂溢性皮炎、湿疹等。治疗旨在用皮质类固醇或抗组胺药缓解症状。阿昔洛韦在某些情况下可能有帮助。严重的情况可能会受益于紫外线光疗。怀孕期间的疾病有时与流产有关。
Pityriasis rosea is a common rash that usually begins with a single patch on the trunk and spreads to cover the trunk and limbs. Diagnosis relies on clinical examination. The initial patch appears red with a raised border and sunken center. The rash typically emerges about two weeks later. Patients may experience fatigue, nausea, headaches, joint pain, swollen lymph nodes, fever, and sore throat alongside the rash. Similar conditions include syphilis, seborrheic dermatitis, eczema, and others. Treatment aims to alleviate symptoms with corticosteroids or antihistamines. Acyclovir may help in some cases. Severe instances may benefit from UV phototherapy. The disease during pregnancy sometimes has been linked to miscarriage.

In most cases, PR does not influence pregnancy or birth outcomes. Analysis of pooled data from our study and from previous studies revealed that the week of pregnancy at onset of PR was inversely associated with an unfavorable outcome (odds ratio [OR] = 0.937; 95 % CI 0.883 to 0.993). In addition, duration of PR (OR = 1.432; 95 % CI 1.129 to 1.827), additional extracutaneous symptoms (OR = 4.112; 95 % CI 1.580 to 10.23), and widespread rash distribution (OR 5.203, 95 % CI 1.702 to 14.89) were directly associated with unfavorable outcome.
Pityriasis rosea 是一种常见的皮肤病，通常影响青少年（10-35 岁），女性稍多。它突然开始，通常在树干上出现一个被称为 herald patch 的斑块，随后出现由浅灰色环包围的粉红色椭圆形小斑点的皮疹。这些斑点通常在树干上形成类似 Christmas tree 的图案。皮疹通常持续约 6 至 8 周。 Pityriasis rosea 影响约 0. 68% 去看皮肤科医生的人，但这可能从 0. 39% 到 4. 8% 不等。
Pityriasis rosea (PR) is a relatively common, self-limited papulo-squamous dermatosis of unknown origin, which mainly appears in adolescents and young adults (10-35 years), slightly more common in females. It has a sudden onset, and in its typical presentation, the eruption is preceeded by a solitary patch termed “herald patch”, mainly located on the trunk. Few days later, a secondary eruption appears, with little pink, oval macules, with a grayish peripheral scaling collarette around them. The secondary lesions adopt a characteristic distribution along the cleavage lines of the trunk, with a configuration of a “Christmas tree”. In most cases, the eruption lasts for 6 to 8 wk. Its incidence has been estimated to be 0.68% of dermatologic patients, varying from 0.39% to 4.8%.

虽然病因尚不完全清楚，但据信与人类疱疹病毒 6 型或人类疱疹病毒 7 型有关。它似乎不具有传染性。某些药物可能会导致类似的皮疹。诊断基于症状，通常不需要活检。
作为一种常见疾病，约 1.3% 的人在某个时间点受到影响。它最常发生在 10 岁至 35 岁之间的人群中。
○ 诊断和治疗
如果持续超过 1 个月，可能需要进行详细检查以将其与其他疾病（副牛皮癣、梅毒）区分开来。
