Multifocal neurilemomas in different nerves of the same upper extremity

Area of Science:

• Neurosurgery
• Oncology
• Orthopedics

Background:

• Neurilemomas are benign nerve sheath tumors.
• Multifocal occurrence is rare, especially across different nerves in one limb.

Observation:

• A case of seven multifocal neurilemomas originating from distinct nerves in the same upper extremity is presented.
• Surgical excision of all tumors was performed with careful attention to nerve preservation.

Findings:

• Common characteristics of multifocal neurilemomas in the upper extremity are detailed.
• The inherent risk of nerve damage during surgical removal of multiple tumors is discussed.

Implications:

• Intracapsular excision is proposed as a technique to reduce operative nerve injury.
• This approach aims to improve outcomes for patients with multifocal neurilemomas.
