Reticulated telangiectatic erythema (RTE) is a rare skin reaction to extraneous materials. We present three cases in which asymptomatic persistent erythemas developed in the area of implantation after medical devices were inserted. Topical and systemic treatment did not improve the skin changes. Patch testing including applied materials showed negative results in all cases. Histological investigation of punch biopsy specimens showed moderate dilatated vessels and a slight lymphocytic infiltrate. Due to our findings and in synopsis with the clinical impression we diagnosed RTE. As RTE is asymptomatic in most cases, the devices need not be removed.
网状毛细血管扩张性红斑（RTE）是一种对外源性物质罕见的皮肤反应。我们报告了3例病例，在插入医疗设备后，植入部位出现了无症状的持续性红斑。局部和全身治疗均未改善皮肤变化。包括所用材料在内的斑贴试验在所有病例中均呈阴性结果。钻孔活检标本的组织学检查显示血管中度扩张，并有轻度淋巴细胞浸润。根据我们的发现并结合临床印象，我们诊断为RTE。由于RTE在大多数情况下无症状，无需移除设备。
