Summary

The glomus tumour is mostly a benign growth that most frequently occurs in the subungual area or within the pulp of the distal phalanx of the fingers. Its incidence is very rare. Glomus tumour is clinically characterized by

pain,
tenderness, and
cold sensitivity.

Despite this typical manifestation, the correct diagnosis is mostly determined after several months or years, and patient is often repeatedly examined by physicians of various specializations.

The glomus tumour can cause the blue discoloration of the nail or form a palpable nodule within the pulp. X-ray examination does not show the tumour directly but it can expose the bony defect in the distal phalanx. By contrast, MR Imaging can demonstrate well-bordered formation, thus helping to locate the tumour and select the appropriate surgical approach. MRI can also indentify the rare occurrence of multiple glomus tumours. Surgical extirpation of the tumour under local or general anaesthesia is the treatment of choice.

Key words:
glomus tumour, distal phalanx, MRI, surgical treatment.
