Two cases of lichen amyloidosis of the auricular concha are presented here, supplementing the already approximately twenty cases of lichen amyloidosis of the auricular concha reported to date. The first patient is a 60-year-old woman who presented with a 4-year history of an itchy rash that started in the bowl of her left ear, and soon after appeared on the right side as well. The second patient is a 44-year-old woman who presented with a long-standing pruritic rash on her upper back. This had become noticeably darker over the past several years. In one of the two cases lichen amyloidosis of the auricular concha reported here, concomitant macular amyloidosis of the back was present. Combined cases of lichen and macular amyloidosis are termed biphasic amyloidosis, and provide support to the theory that these two variants of amyloidosis exist on the same disease spectrum.
本文报告两例耳甲腔苔藓样淀粉样变病例，补充了迄今为止已报道的约20例耳甲腔苔藓样淀粉样变病例。首例患者为一名60岁女性，有4年瘙痒性皮疹病史，皮疹始于左耳甲腔，随后不久右侧也出现。第二例患者是一名44岁女性，其上部背部有长期瘙痒性皮疹，在过去几年中颜色明显变深。在本文报告的两例耳甲腔苔藓样淀粉样变病例中，有一例同时存在背部斑状淀粉样变。苔藓样和斑状淀粉样变的合并病例称为双相淀粉样变，为这两种淀粉样变变体存在于同一疾病谱的理论提供了支持。
