Uncommon Cause of Severe Chronic Finger Pain.

Glomus tumour (GT) is a rare, benign perivascular lesion which arises from the glomus body. GT is most common in the subungual area of fingers. The classical clinical features are pain, cold intolerance, and pinpoint tenderness which are nonspecific. A 48-year-old lady presented with an 8-year history of swelling in the subungual region of her left ring finger and chronic pain with severe exacerbations to touch and exposure to cold. A small, solitary, bluish purple swelling of 0.5 × 0.5 cm was present in the subungual region of the left ring finger with pinpoint tenderness. Magnetic resonance imaging and colour Doppler were suggestive of GT. The lesion was removed en bloc using the subungual approach. The biopsy confirmed the diagnosis of GT. There was a marked reduction in the level of pain and discomfort postoperatively. A subungual small GT can be a rare but treatable cause of chronic finger pain. Most ideal treatment is complete excision. [ABSTRACT FROM AUTHOR]
