Acrodermatitis continua of Hallopeau (ACH) 连续性肢端皮炎
Acrodermatitis continua of Hallopeau (ACH) is a rare, sterile pustular eruption of one or more digits. This condition presents itself with tender pustules and underlying erythema on the tip of a digit, arising on a finger more frequently than a toe. As far as classification, ACH is considered a localized form of palmoplantar pustular psoriasis. The eruption typically occurs after local traumas or infections, but such a history is not always present and various other etiologies have been noticed including infectious, inflammatory, and genetic causes. The natural progression of ACH is chronic and progressive, often resulting in irreversible complications such as onychodystrophy that can result in anonychia, as well as osteitis that can result in osteolysis of the distal phalanges. Because of the rarity of ACH, there have been no randomized controlled studies to evaluate therapies, resulting in an absence of standardized treatment guidelines.
We presented a 50-year-old otherwise healthy woman with a 2 year history of Acrodermatitis continua of Hallopeau treated with herbal medication, pustules and erythema lesion healed completely after 20 months. We thank this patient for sending us the photos via WhatsApp and giving us consent for these photos to be used as testimonial.
连续性肢端皮炎 (ACH) 是一种罕见的无菌性脓疱疹，长于一个或多个手指。该病症表现为指尖有触痛的脓疱和潜在的红斑，脚趾更常见于手指。就分类而言，ACH 被认为是脓疱性银屑病的一种局部形式。皮疹通常发生在局部创伤或感染后，但这种病史并不总是存在，并且可能还有其他病因，包括感染、神经、炎症和遗传因素。 ACH 的自然进展是慢性和进行性的，通常会导致不可逆的并发症，例如可导致无甲的甲营养不良，以及可导致远端指骨骨质溶解的骨炎。由于 ACH 的罕见性，没有随机对照研究来评估治疗，导致缺乏标准化的治疗指南。
我们治疗一位50岁其他方面健康女性罹患连续性肢端皮炎2年，经过20个月的治疗和追踪，脓疱和红斑皮疹完全消退。我们感谢患者通过WhatsApp将照片发送给我们，并同意将其发表。
