Penetrating skin degeneration

The clinical manifestations of elastic pseudoxanthoma are calcification of the skin epidermis or penetrating skin degeneration. Elastic pseudoxanthoma (pseudoxanthoma elasticum) was once called diffuse xanthelasma in the early days, and later it was also known as atypical xanthomas and dystrophic elastic fibrosis. Due to different genetic methods, they can be divided into autosomal dominant heredity and autosomal recessive heredity. Each type is divided into two groups. Clinically, chromosomal dominant Ⅰ, Ⅱ and autosomal recessive Ⅰ are common. Recessive chromosome group II is relatively rare, and the dominant genetic symptoms are usually more severe than the recessive inheritance.
