title: Pathology consultation. Nomenclature of developmental tumors.
abstract: The terms hamartoma, choristoma, embryoma, teratoma and dermoid refer to separate and distinct tumors in the head and neck. Not only is the histogenesis unique to each entity, their clinicopathologic presentations are such that they may be easily separated. The diagnostic terminology is not interchangeable although contemporary use would make it seem so.
