Abstract

Abstract: Erythema papulatum centrifugum (EPC), also known as erythema papulosa semicircularis recidivans, is a rare dermatological condition characterized by single or multiple annular or semi-annular centrifugally growing lesions surrounded by tiny erythematous papules typically observed on the trunk. EPC is prevalent, particularly in Japan and China, although only a few cases have been reported outside Asia. Herein, we present the case of a 47-year-old female from Thailand who experienced a pruritic annular erythematous rash on her right arm for two months. The diagnosis of EPC was established based on clinical manifestations and confirmed by histopathological examination. The lesions resolved after one month of treatment with 0.1% betamethasone valerate cream and avoiding warm weather. This case report contributes to the understanding of EPC, which may be underrecognized in clinical practice due to its self-limiting nature and frequent misdiagnosis. Furthermore, this article provides a comprehensive review of 17 previously reported cases of EPC, focusing on their detailed descriptions.

离心乳头状红斑：未被充分认识的环状红斑病例报告

摘要：离心性红斑丘疹（EPC）又称半环形红斑丘疹（erythema papulosa semicircularis recidivans），是一种罕见的皮肤病，其特征是单个或多个环形或半环形离心生长的皮损，周围有微小的红斑丘疹，通常出现在躯干。EPC很常见，尤其是在日本和中国，但亚洲以外地区仅有少数病例报道。在此，我们介绍一例来自泰国的 47 岁女性病例，她的右臂出现瘙痒性环状红斑皮疹长达两个月。根据临床表现确诊为 EPC，并经组织病理学检查确诊。在使用 0.1% 倍他米松戊酸酯乳膏和避免温暖天气治疗一个月后，皮损消退。本病例报告有助于人们了解 EPC，由于其自限性和经常被误诊，临床实践中可能对其认识不足。关键词：环状红斑；环状病变；肾上腺汗腺；无形红斑；肾周炎症；出汗

期刊介绍： Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal. Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest. The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care. All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
