Frequently, I1 have pointed out how limited is the experience of even the most experienced among us with regard to the knowledge and behavior of glomus jugulare tumors and how unwise it is to be dogmatic or arbitrary with respect to some of the unsolved clinical problems: I. Metastasis: How frequently does it occur and to what areas? II. Nomenclature: How shall these tumors ultimately be designated? III. Therapy: What can be adjudged a rational method of treatment?
