Focal scleroderma (limited)

It is relatively benign. In the development of the disease, three stages are distinguished: swelling of the skin, its tightening and sclerotherapy, then atrophy and pigmentation. A lesion occurs most often on the body, less often on the limbs. It begins with the appearance of a violet-red spot, which gradually thickens and increases. Subjective sensations, as a rule, are absent. Gradually, the central part of the focus acquires a yellowish-white color with a waxy gloss and a smoothed skin pattern, it becomes dense, hair falls out. Subsequently, the violet ring disappears, the densified area becomes softer, sinks. A spot remains on the site of the rash - an over-pigmented and atrophied area of ​​the skin.
