摘要

鋅對人體來說是個微量而重要的元素。它影響了很多體內的代謝途徑。鋅缺乏在全世界，尤其是在發展中國家特別盛行。鋅缺乏分為先天和後天兩種類型。鋅缺乏影響了我們身體內的皮膚、腸胃道、中樞神經、免疫調節、骨骼以及生殖系統。本報告描述一位88歲女性，因為雙側上肢以及下肢在最近幾天出現了對稱的紅斑性病灶，且合併有脫屑之情形。抽血報告發現血中之鋅離子濃度偏低，給予補充口服之元素鋅之後，皮膚症狀在五個月內逐漸緩解，而停藥後皮膚症狀並無復發。因此類疾病在老年人身上偶可見到，故本文旨在提醒臨床醫師鋅缺乏引起之皮膚炎在老年人為不算少見、無特別的臨床表徵但是可治癒之疾病。

Zinc is an essential trace element required by human body as it affects multiple metabolic pathways. Zinc deficiency, however, has been a global health concern, especially in developing countries. No matter inherited or acquired, zinc deficiency exerts influences on skin, gastrointestinal, central nervous, immune, skeletal and reproductive systems. We report an 88-year-old female with skin manifestation of acquired zinc deficiency and decreased plasma zinc level. With oral zinc supplement therapy, the skin lesions subsided gradually in 5 months, and there was no recurrence when the oral supplement was discontinued. The objective of this case report is to remind physicians that zinc deficiency remains prevalent, particularly in moderate form, and has non-specific clinical presentations in the elderly. Though treatable, it may have complications if not carefully managed.
