Summary
Glomus tumors are rare, benign neuro-myo-arterial tumors causing severe hand pain, primarily in young women. Diagnosis relies on clinical suspicion and advanced imaging, with surgical resection as the primary treatment.
Area of Science:
- Vascular Surgery
- Orthopedic Oncology
- Hand Surgery
Context:
- Glomus tumors are rare neuro-myo-arterial neoplasms.
- They constitute 1-5% of all hand tumors.
- Predominantly affect young adult females, often presenting as solitary or multiple lesions.
Purpose:
- To review the clinical presentation, diagnosis, and management of glomus tumors.
- To highlight the diagnostic utility of Magnetic Resonance Angiography (MRA).
- To emphasize surgical resection as the definitive treatment.
Summary:
- Characterized by acute, focalized pain, often triggered by pressure, leading to immediate hand withdrawal.
- Differential diagnoses are extensive, including neurilemmoma, melanoma, and angioma.
- Radiography reveals bone erosion in approximately one-third of cases.
- MRA is the preferred non-invasive modality for diagnosis and localization.
Impact:
- Accurate diagnosis and localization are crucial for effective treatment planning.
- Complete surgical resection offers a definitive cure.
- Understanding glomus tumors improves patient outcomes and surgical strategies in hand surgery.
