In cases in which the eruption is entirely zoniform, the morphologic observations may be so characteristic as to make the diagnosis readily apparent clinically. We have observed, however, that in many instances when cases of linear dermatoses are presented before dermatologic societies there is disagreement as to the diagnosis. The discussion of these cases usually includes the consideration of nevus, lichen planus and psoriasis, but at times the evidence presented does not permit the inclusion of the condition
