Giant Cell Tumours of Hand Bones: a Report of Two Cases

[摘要] Giant cell tumor (GCT) of bone is a relatively common type of benign tumour involving the epiphyseal region of tubular bones such as the femur, tibia, and humerus but Giant cell tumour of hand bones are rare with an incidence of around 1–4 % [1–7]. Although GCT are benign tumours, but they can be locally malignant, and when so they have a higher recurrence. Giant cell lesion of the small bones were previously known as ‘Giant cell reparative granuloma’ but now there is a different entity called Giant cell tumour of the small bones of the hands and feet [3]. The recurrence rate of GCT of the small bones in the literature was found to be similar to the higher side of incidence of recurrence of GCT of long bones .i.e. 27 to 65 % after isolated curettage, 20 to 35 % after curettage with adjuvants, and 10 to 15 % after en bloc resection, for GCT in the long [1, 4, 7, 8]. In hand bones, this tumour usually affect metaphyseal region with relatively higher recurrence than for other locations [1, 8]. It becomes symptomatic early in the hand because of tight compartments thus expansion of bone may give pain, and swelling, followed by early loss of function [3].
