Pasini-Pierni progressive skin atrophy
Introduction
Pasini-Pierni Introduction to Progressive Skin Atrophy Pasini-Pierni progressive idiopathic skin atrophy (progressiveidiopathicatrophyofPasiniandPierni), since Pasini-Pierni reported this disease in 1923, there is limited superficial atrophic scleroderma (atrophosclerma superficialiscircumscripta), diffuse idiopathic skin atrophy (atrophiacutisidiopathicadiffusa ) and so on. It is a special type of pigmented skin atrophy. There is an atrophic subtype that is thought to be a localized scleroderma. basic knowledge The proportion of illness: 0.018% Susceptible people: more than adolescents, more men than women Mode of infection: non-infectious Complications: keloids

The epidermis is atrophied and there is no special change in the subcutaneous layer.

diagnosis
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
