<unk>  is a form of<unk>  associated with oncostatin M receptor. This type of<unk>  has been divided into the following types: * Macular<unk>  is a cutaneous condition characterized by itchy, brown, rippled macules usually located on the interscapular region of the back. Combined cases of lichen and macular<unk>  are termed biphasic<unk> , and provide support to the theory that these two variants of<unk>  exist on the same disease spectrum. * Lichen<unk>  is a cutaneous condition characterized by the appearance of occasionally itchy lichenoid papules, typically appearing bilaterally on the shins.
