Lymphocytoma cutis due to pierced earrings.
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.
