■玫瑰糠疹(PR)是一种常见的疾病,然而神秘,以独特临床表现为特征的皮肤病。尽管流行,PR的病因和发病机制仍然难以捉摸。
■研究PR患者的流行病学和临床方面。目的研究皮肤镜检查结果并进行组织病理学相关性。
■对50名患者进行了横断面研究。获取了详细的临床病史,并进行了检查,然后进行了皮肤镜检查。在标准偏差的帮助下,提供了年龄和疾病持续时间等定量数据。定性风险因素,比如性别,年龄组,症状学,病变部位,发现或皮肤检查,皮肤镜检查结果,和组织病理学发现,在频率和百分比的帮助下呈现。
■PR显示男性优势,平均发病年龄为30.8±15.7岁。40%的患者有不典型的临床表现。最常见的皮肤镜检查结果是弥漫性红色背景(58%),外周烟圈秤(62%),和周围点状血管(50%)。在组织病理学上,最常见的发现是海绵状体(44%),角化不全(38%),不规则棘皮病(34%),血管周围淋巴细胞浸润(56%),和红细胞外渗(36%)。
■由于COVID,样本量较小。由于这是一项横断面研究,因此无法对患者进行随访。
■虽然PR的诊断是临床的,在非典型病例中,皮肤镜检查是很困难的。它还有助于确定病变的年龄,从而帮助决定患者的治疗策略。活检仍然是排除PR其他差异的黄金标准。
UNASSIGNED: Pityriasis Rosea (PR) is a common, yet enigmatic, dermatological condition characterized by a distinctive clinical presentation. Despite its prevalence, the aetiology and pathogenesis of PR remain elusive.
UNASSIGNED: To study the epidemiological and clinical aspects of patients with PR. To study dermoscopic findings and carry out histopathological correlation.
UNASSIGNED: A cross-sectional study of 50 patients was conducted. A detailed clinical history was taken and an examination was done followed by a dermoscopy. Quantitative data like age and duration of disease are presented with the help of standard deviation. Qualitative risk factors, like gender, age groups, symptomatology, site of lesion, findings or cutaneous examination, dermoscopy findings, and histopathology findings, are presented with the help of frequency and percentages.
UNASSIGNED: PR shows male preponderance and mean age of occurrence being 30.8 ± 15.7 years. Forty per cent of patients had an atypical clinical presentation. The most frequently seen dermoscopy findings were diffuse red background (58%), peripheral collarette scale (62%), and peripheral dotted vessels (50%). On histopathology, the most common findings were spongiosis (44%), parakeratosis (38%), irregular acanthosis (34%), perivascular lymphocytic infiltrate (56%), and red blood cell extravasation (36%).
UNASSIGNED: Sample size was less due to COVID. As this was a corss-sectional study follow up of patients could not be done.
UNASSIGNED: While the diagnosis of PR is clinical, it is difficult in atypical cases where dermoscopy comes to the aid. It also helps identify the age of lesions, thus helping decide the treatment strategy for patients. Biopsy remains the gold standard in ruling out other differentials of PR.
