We report two cases of lymphocytoma cutis caused by pierced earrings, with the results of patch tests and X-ray microanalyses on electron microscopy. We detected zinc through scanning electron microscopy from the specimen of Case 1 and gold and titanium through transmission electron microscopy from Case 2. This is the first report to demonstrate the presence of metal fragments in the lesion, which may suggest the remanence of metal for 20 years, bringing about persistent allergic reaction.
我们报告了两例因穿耳洞导致的皮肤淋巴细胞瘤病例，并给出了斑贴试验结果以及电子显微镜下的X射线微量分析结果。我们通过扫描电子显微镜从病例1的标本中检测到了锌，通过透射电子显微镜从病例2中检测到了金和钛。这是首次证明病变中存在金属碎片的报告，这可能表明金属残留长达20年，引发了持续的过敏反应。
