Why Vitiligo Present Symmetrical Distribution?

The vitiligo distribution present on the symmetrical distribution, vitiligo can be distributed irregularity or symmetrically, or it distribute along the nerve or unilateral distribution, or it can confined in a focal part. These all are normal distribution situation, the symmetrical distribution are one of the generalized vitiligo types.

Clinic characteristic for generalized vitiligo is that the white patches distributed many part of body. It presents certain symmetry. Such as if the left arm appear some white patches, the right arm also will appear some white patches. Why the white patches distribute in symmetry way is because it close related with the nervous system and the main and collateral channels.

Generalized type vitiligo belongs to vulgaris vitiligo type. It is characterized by scatted patches that are widely distributed, and the white patches are mainly small plaques. So how does the patients to distinguish if it is generalized vitiligo?

There are some characteristics for the generalized vitiligo.

Firstly, the white patches are scatted in many part of body. It distribute in a symmetry way not confined in certain part, it rare appear some cluster phenomenon.

Secondly, the white area is relatively small for generalized vitiligo patients it will not exceed half of the surface body surface. This characteristic is mainly to distinguish the generalized vitiligo and the universal vitiligo. If the white patches surface not more than half of the body surface, so we can confirm that it as the generalized type vitiligo.

So the generalized vitiligo should pay attention to that, if they didn’t receive the treatment timely, it will develop to the universal vitiligo and make it more difficulty to treat.
