99mTC-MDP bone scanning in a subungual glomus tumour.

A 37-year-old female patient with four months history of paroxysmal pain in the left index finger was referred to our department for 99mTC-MDP scintigraphy. Radiographic studies of the patient showed a lytic tumour in the distal phalanx of the left second finger compatible with a glomus tumour. The scan showed mild decreased activity in the blood pool phase and minimal increased activity on the delayed images. The patient underwent surgery and a glomus tumour was removed. To the extent of our knowledge, this is the first case of bone scan in a glomus tumour of the finger reported in the literature.
