Pemphigus vegetans is a very rare form of pemphigus, in which warty sores appear and are usually distributed over much of the body. Negative ANA tests also occur with discoid lupus, another disease that is sometimes confused with pemphigus based on the appearance of the problem. Since treatment is usually necessary for life, it is really important to be certain of the diagnosis before committing to lifelong therapy, whenever possible. Another similar disease is bullous pemphigus, which affects primarily collies, shelties and dobermans. This disorder affects a different layer of the skin but otherwise looks a lot like pemphigus vulgaris.
