Is histopathological diagnosis useful in choosing treatments for tumors of the temporal bone?

We were pleased to read the article by Olcott C. andStrasnick B. titled "A blue middle ear mass: Cholesterol granuloma mimicking a glomus tumor and endolymphatic sac tumor". Am J Otolaryngol.2017;38(1):100-102 [1], which presents very important clinical observations. Based on our experience and the literature review, we would like to present some comments on this problem. The benign tumors of the temporal bone (TB) have been divided into three groups: cholesterol granuloma (CG), glomus tumor (GT) and endolymphatic sac tumor (ELST) [1].
