Abstract

BackgroundGlomus tumors in the digital nerve are extremely rare. Multiple intraneural glomus tumors in different digital nerve fascicles have not been previously reported.Case presentationWe report the case of a 54-year-old male with a 1-year history of progressive numbness of the middle finger with point tenderness at the level of the middle phalanx. Surgical incision revealed the presence of two glomus tumors within different fascicles of the ulnar digital nerve of the middle finger.One tumor was excised along with surrounding fascicle, the other was removed leaving the fascicle intact. Subsequently, the patient regained function of the finger and no tumors have recurred.ConclusionsPatients and physicians should be aware of the properties of intraneural glomus tumors so that early diagnosis and treatment can be sought.

Highlights

Glomus tumors in the digital nerve are extremely rare
This study describes two intraneural glomus tumors located in different fascicles of the same digital nerve
Glomus tumor is a rare benign tumor that most frequently occurs in the glomus body in the subungual regions of digits [8]

Summary

Introduction

Glomus tumors in the digital nerve are extremely rare. Multiple intraneural glomus tumors in different digital nerve fascicles have not been previously reported. Background Glomus tumors are rare benign neoplasms that most frequently occur in the subungual regions of digits. Previous studies have reported six cases of solitary intraneural glomus tumors [1,2,3,4,5,6] and one case of multiple glomus tumor within one single swollen fascicle [7].
