鞭状红斑,也被称为鞭毛状皮炎,鞭毛色素沉着过度,或者香菇皮炎,是一种罕见的多灶性皮肤爆发,其特征是线性红斑性病变类似于鞭毛伤口。该病例报告详述了一名31岁的非洲裔美国男性出现瘙痒的鞭毛状红斑的进行性发作,红斑,色素沉着过度,面部的线性病变,树干,和他食用香菇后的上肢。经典的,这种爆发是在摄入生的或未煮熟的香菇之后发生的。这个案例强调了临床诊断的重要性,由于组织学发现的非特异性,活检作为诊断工具的作用有限。因此,正确的诊断依赖于仔细的病史记录,包括饮食变化,开始任何新的药物,和症状的进展。大多数情况下是自我限制的,喷发持续长达三周。治疗旨在通过局部皮质类固醇和口服抗组胺药来缓解症状,减少相关的瘙痒和皮肤变化。
Flagellate erythema, also known as flagellate dermatitis, flagellate hyperpigmentation, or shiitake dermatitis, is a rare multifocal cutaneous eruption characterized by linear erythematous lesions similar to flagellation wounds. This
case report details the progressive onset of flagellate erythema in a 31-year-old African American male presenting with pruritic, erythematous, hyperpigmented, linear lesions of the face, trunk, and upper extremities following his consumption of shiitake mushrooms. Classically, this eruption arises subsequent to the ingestion of raw or undercooked shiitake mushrooms. This
case underscores the importance of clinical diagnosis, as the role of biopsy as a diagnostic tool is limited due to the nonspecific nature of histological findings. Therefore, proper diagnosis is reliant upon careful history taking, including dietary changes, initiation of any new medications, and progression of symptoms. Most cases are self-limiting, with eruptions persisting for up to three weeks. Treatment aims to provide symptomatic relief through topical corticosteroids and oral antihistamines, reducing associated pruritus and skin changes.
