Abstract

To describe human temporal bones with bilateral glomus tympanicum tumors. Patient is 83-year-old black female who no pulsatile tinnitus. The histopathologic characteristics of human temporal bones after death were setting Department of Otolaryngology of University of Minnesota in USA. Histopathologic observation of temporal bones showed bilateral small glomus tympanicum tumors limited to the promontory. Although there was bilateral tinnitus, there was no pulsatile tinnitus, no conductive hearing loss and both of the tympanic membranes were intact. Histopathologic observation of temporal bones after death showed bilateral glomus tympanicum tumors. To our knowledge, this is the first reported case of bilateral glomus tympanicum tumors.

Highlights

Case ReportAn 83-year-old black female who had a 14 month history of tinnitus died from adenocarcinoma of the duodenum metastatic to the liver and bilateral lungs
The nets, described as Zellballen,[1] are separated by reticulin fiberovasucular strands (Figure 2). These findings are consistent with a diagnosis of glomus tympanicum tumors

Summary

Introduction

An 83-year-old black female who had a 14 month history of tinnitus died from adenocarcinoma of the duodenum metastatic to the liver and bilateral lungs. An audiogram from 10 years previous showed sensorineural hearing loss of the high frequencies in both ears. On examination both tympanic membranes were intact. The histopathologic characteristics of human temporal bones after death were setting Department of Otolaryngology of University of Minnesota in USA.
