Giant Cell Tumor Of The Distal Ulna - A Rare Presentation Tr
The location of a giant cell tumor (GCT) at the distal end of the ulna is very rare with a reported incidence from 0.45% to 3.2%. Various treatment options have been proposed. En-bloc resection of the distal part of the ulna maintaining extra-lesional margins with or without reconstruction or stabilization of the ulnar stump is the more oncologically advantageous treatment for GCT located in this area. We present one patient with GCT of the distal ulna, treated by wide resection of the distal ulna followed by stabilisation of the remaining ulna using one half of the extensor carpi ulnaris (ECU) tendon.
A 22-year-old Indian female, student by occupation, presented with painful progressive swelling over the ulna aspect of her left distal forearm over the past six months. There was no history of any other swelling in the body, fever, loss of weight or appetite, or history of similar complaints in the past. The family, occupational, recreational and drug histories were not significant. The general physical and systemic examinations were within normal limits. On examination, there was a diffuse oval swelling of the distal left forearm along the ulnar aspect measuring 6 x 4 cm. The mass was firm in consistency and tender with normal overlying skin and temperature. The overlying skin was of normal colour and temperature. There was no overlying scar, sinus or prominent veins. It was free from the overlying skin but adherent to the underlying bone. The range of motion of wrist was normal with supination terminally painful and restricted. The distal neurovascular status was normal and grasping power equal in both hands.
