Pityriasis rosea is a common skin condition seen in children and adults. Whereas pityriasis rosea is a benign condition, it is important to distinguish it from other childhood exanthems.
Pityriasis rosea can present in a variety of manners. Most often a herald patch precedes the generalized eruption, although this is not always the case. Pityriasis rosea may lead to undesirable outcomes when affecting pregnant women. Guttate psoriasis, secondary syphilis, cutaneous lupus erythematosus, capillaritis, pityriasis versicolor, nummular eczema, and cutaneous T-cell lymphoma are important to consider in the differential diagnosis of pityriasis rosea.
Pityriasis rosea is self-limiting, usually lasting 1-3 months. Treatment may be considered in certain cases, although there is a paucity of medical studies supporting any definitive treatment. However, treatment may be warranted for other conditions that mimic pityriasis rosea.
玫瑰糠疹是儿童和成人中常见的一种皮肤疾病。尽管玫瑰糠疹是一种良性病症，但将其与其他儿童疹病区分开来很重要。
玫瑰糠疹可以有多种表现形式。多数情况下，在泛发性皮疹出现之前会先出现一个先驱斑，不过并非总是如此。玫瑰糠疹在影响孕妇时可能会导致不良后果。点滴状银屑病、二期梅毒、皮肤红斑狼疮、毛细血管炎、花斑糠疹、钱币状湿疹和皮肤T细胞淋巴瘤在玫瑰糠疹的鉴别诊断中是需要考虑的重要疾病。
玫瑰糠疹是自限性的，通常持续1至3个月。在某些情况下可以考虑进行治疗，尽管支持任何确定性治疗的医学研究很少。然而，对于其他类似玫瑰糠疹的病症，治疗可能是必要的。
