ABSTRACT

Introduction: Schwannomas are benign nerve sheath tumors that are rare in the radial nerve. Case report: a 62-year-old man presented with a mass in the distal right radius with a 5-year history of progression and associated paresthesias. Ultrasound revealed a well-defined, heterogeneous, and vascularized lesion. Surgical resection was performed without complications, and histopathology confirmed a schwannoma. Conclusion: due to its slow growth and encapsulated nature, the ideal treatment is complete excision. This case highlights the importance of early diagnosis and appropriate surgical management to prevent neurological sequelae.
