Primary cutaneous amyloidosis (PCA) is a chronic pruritic skin disorder with characteristic amyloid deposits in the papillary dermis. We report three cases of PCA, which shared common features of hypopigmentation as a predominant feature with or without reticular hyperpigmentation, no itching, adult onset and dermal papillary amyloid deposition. These cases did not conform to the usual features of PCA.
原发性皮肤淀粉样变性（PCA）是一种慢性瘙痒性皮肤病，其特征是在真皮乳头层有特征性淀粉样物质沉积。我们报告了三例 PCA，这些病例具有共同的特征，即色素减退为主，或伴有网状色素沉着，无瘙痒，成人发病和真皮乳头淀粉样物质沉积。这些病例不符合 PCA 的常见特征。
