Treatment of a large aneurysmal bone cyst in a 15-year-old boy using a corticospongial bone graft and a 12-year follow-up after operation.

We report the case of a 15-year-old boy with a large aneurysmal bone cyst in the third metacarpal, which was operated on radically with excision of the bone and grafting from the distal radius. At 12-year follow-up the patient had good cosmetic results and a perfectly functioning hand.

Multiple brown tumours of the upper extremity in a patient with secondary hyperparathyroidism as a result of chronic renal failure.

A man with chronic renal failure was referred to the hand clinic because of massive osteolytic tumours in his right arm. Secondary hyperparathyroidism and brown tumours were suggested, and he was treated by subtotal parathyroidectomy. Rapid reduction of the vast tumours was noted postoperatively.
