Summary
Extradigital glomus tumors are uncommon but often misdiagnosed, leading to delayed treatment. Early diagnosis and surgical resection offer excellent outcomes for these painful tumors.
Area of Science:
- Oncology
- Dermatology
- Orthopedic Surgery
Background:
- Glomus tumors are rare neoplasms, with extradigital locations presenting unique diagnostic challenges.
- Delayed diagnosis of extradigital glomus tumors is common, leading to prolonged patient suffering.
Purpose of the Study:
- To review a large series of extradigital glomus tumors to understand their presentation.
- To provide guidelines for improved diagnosis and treatment of extradigital glomus tumors.
Main Methods:
- Retrospective review of extradigital glomus tumors over a 20-year period.
- Documentation of symptom incidence, duration, diagnostic imaging utility, and treatment effectiveness.
Main Results:
- Fifty-six patients with extradigital glomus tumors across various body sites were identified.
- Pain and localized tenderness were prevalent, but the classic triad was rare; average symptom duration exceeded 7 years.
- Magnetic resonance imaging (MRI) was the most effective diagnostic modality; surgical resection provided immediate and sustained pain relief.
Conclusions:
- Extradigital glomus tumors are not rare and have excellent treatment outcomes.
- Misdiagnosis and delayed diagnosis are significant issues, contributing to chronic pain and psychological distress.
- Improved diagnostic guidelines are crucial to reduce morbidity associated with delayed diagnosis.
