In the vast group of linear dermatoses a very particular topographic type can be distinguished, i.e., the axial dermatoses which very electively follow the linear course of Scherington's axial lines. This feature can be found in several dermatoses and particularly in lichen striatus and acantholytic linear naevus. Topographically, the axial dermatoses are quite similar to the pigmentary demarcation lines which also follow the same course. Despite numerous patholgenic unknown facts, the concept of axial dermatoses certainly contributes to a better knowledge of the still obscure linear dermatoses.
