Chemical burns are comparably rare but often result in full-thickness skin defects with frequent involvement of underlying structures. Hands are the most commonly affected injury site and impaired functional outcome is common. We present a case of an unusual chemical burn to the dorsum of the hand of a child secondary to application of a topical anti-wart treatment containing formic acid.
An 11-year-old girl was referred to our outpatient department with a full-thickness injury resulting from a chemical burn having used a topical formic acid solution in the treatment of common warts. On examination, a 20-mm circular full-thickness defect was noted to the dorsum of the hand. The extensor tendons were not involved and there were no signs of infection. She required surgical debridement and local flap coverage. The postoperative recovery was unremarkable.
Through a comprehensive literature review, four common topical solutions used in anti-wart treatment were identified to be associated with burns. Together with our case, this highlights the importance of careful patient education in the usage of common topical over-the-counter treatments.
化学烧伤相对少见，但常导致全层皮肤缺损，且深层结构常受累。手部是最常受影响的损伤部位，功能受损很常见。我们报告一例儿童手部背侧因使用含甲酸的外用抗疣治疗导致的罕见化学烧伤病例。
一名11岁女孩因使用外用甲酸溶液治疗寻常疣导致化学烧伤，出现全层损伤，被转诊至我们的门诊。检查发现，手部背侧有一个20毫米的圆形全层缺损。伸肌腱未受累，无感染迹象。她需要手术清创和局部皮瓣覆盖。术后恢复情况良好。
通过全面的文献综述，确定了四种用于抗疣治疗的常见外用溶液与烧伤有关。结合我们的病例，这凸显了在使用常见非处方外用治疗时对患者进行仔细教育的重要性。
