We have amputated of the distal phalanx of the 4th finger with tumor which histological diagnosed of the giant cell tumor, and after the operation she had skeletal scintigraphy for the distribution of the disease. There were two more lesions in the skull and the iliac wing. When we have found an adenoma of the parathyroid gland, we reinspect of the preparation of the amputated part of the finger. It was the brown tumor with primary hyperparathyroidism. The term “brown tumor” refers to the color of the tumefaction in the gross. The color is caused by rich vascularity with hemorrhages and hemosiderin pigment. The only careful attention to clinical and radiologic features is it possible to separate the brown tumor of hyperparathyroidism from that of solitary neoplasm. Skeletal lesions (brown tumor) in primary hyperparathyroidism are reversible and can be treated by excision of the parathyroid adenomas or of three of the hyperplasic parathyroid.
