Lower extremity glomus tumors: comprehensive review for surgeons

Area of Science:

• Vascular Surgery
• Dermatology
• Oncology

Background:

• Glomus tumors (GT) are rare, benign vascular neoplasms often originating from cutaneous arteriovenous connections.
• These tumors typically occur in the subungual region but can present in the lower extremities.
• Delayed diagnosis of lower extremity glomus tumors is common due to low clinical suspicion.

Observation:

• Glomus tumors in the lower extremity present diagnostic challenges, leading to delayed recognition and treatment.
• Patients may experience prolonged symptoms before a correct diagnosis is established.
• A lack of awareness among healthcare providers, particularly vascular surgeons, contributes to diagnostic delays.

Findings:

• Surgical excision is the primary treatment for glomus tumors and is often curative.
• Prompt diagnosis and surgical management of lower extremity glomus tumors lead to significant symptomatic improvement.
• This report highlights the need for increased awareness of glomus tumors in the lower extremities within the surgical community.

Implications:

• Enhancing physician awareness of lower extremity glomus tumors can reduce diagnostic delays.
• Improved diagnostic accuracy will facilitate timely surgical intervention and patient recovery.
• Further research and case reporting are essential to expand the understanding of glomus tumors, especially in unusual locations.
