Acquired zinc deficiency can develop as a consequence of poor nutritional intake or from dependence on total parenteral nutrition. Acquired zinc deficiency dermatitis classically manifests with erosions and scaly plaques in a periorificial and acral distribution. We present a case of a woman on parenteral nutrition who presented with bullous acrodermatitis mimicking pemphigus foliaceus histopathologically. This case highlights clinical and histopathologic variants of zinc deficiency that may lead to a delay in diagnosis.
获得性锌缺乏可因营养摄入不足或依赖全胃肠外营养而发生。获得性锌缺乏性皮炎的典型表现为口周和肢端分布的糜烂和鳞屑性斑块。我们报告一例接受胃肠外营养的女性患者，其组织病理学表现为大疱性肢端皮炎，酷似落叶型天疱疮。该病例突出了锌缺乏可能导致诊断延迟的临床和组织病理学变异。
