A glomus tumour is a small, benign (non-cancerous) growth that typically develops under the fingernail. It arises from specialised structures involved in regulating blood flow in the fingertip.
Despite being small, glomus tumours can cause severe, localised pain. The condition is often associated with extreme sensitivity to cold and discomfort when pressure is applied to the fingertip.
Because the tumour is not always visible, diagnosis can be delayed. However, the pattern of symptoms is often characteristic.
Treatment is usually surgical and aims to remove the tumour and relieve symptoms.
Symptoms are often very specific and may include:
Pain may be disproportionate to the size of the lesion.
Symptoms are often very specific and may include:
Pain may be disproportionate to the size of the lesion.
Diagnosis is based on clinical assessment and the pattern of symptoms.
Investigations may include:
These tests help confirm the diagnosis and guide treatment planning.
Treatment is usually surgical.
Surgical removal of the tumour is recommended in most cases and is typically curative.
Non-surgical treatment is generally not effective for this condition.
Surgical treatment involves removing the tumour, often through a small incision in or around the nail.
The procedure is typically performed as a day-case under local anaesthetic.
Care is taken to minimise damage to the nail and surrounding structures.
Recovery following surgery is usually straightforward.
Recovery typically involves:
Pain relief is often immediate following removal of the tumour.
As with any surgical procedure, there are potential risks, although these are uncommon.
Possible complications include:
Very rarely, a condition known as complex regional pain syndrome (CRPS) can occur, leading to prolonged pain and sensitivity.
You should seek medical advice if you experience persistent fingertip pain, particularly if it is severe, localised or triggered by cold.
Early assessment can help confirm the diagnosis and provide effective treatment.
