Multiple intraneural glomus tumors in different digital nerve fascicles

Area of Science:

• Nerve surgery
• Oncology
• Histopathology

Background:

• Glomus tumors are rare, particularly within digital nerves.
• Multiple intraneural glomus tumors within separate fascicles have not been previously documented.

Observation:

• A 54-year-old male presented with a year of progressive middle finger numbness and tenderness.
• Surgical exploration identified two distinct glomus tumors within different fascicles of the ulnar digital nerve.

Findings:

• One tumor was excised with its fascicle; the second was removed preserving the fascicle.
• Post-operative recovery was complete, with no evidence of tumor recurrence.

Implications:

• This case highlights the possibility of multiple intraneural glomus tumors.
• Awareness of this rare presentation is crucial for timely diagnosis and effective treatment of digital nerve glomus tumors.
