Ultrastructure of Brown Tumor of Hyperparathyroidism
Ultrastructural Pathology, 1990The ultrastructure of two cases of brown tumor of hyperparathyroidism is described. The most frequent cells found are multinucleated giant cells and fibroblasts. The giant cells have ultrastructural features similar to osteoclasts such as numerous mitochondria, dilated rough endoplasmic reticulum, and short filopodia.

A case of brown tumor of hyperparathyroidism in a young girl with a long history of chronic renal failure and hemodialysis therapy is reported. The diagnosis can be reached with the aid of the classic skeletal radiological sign which address the evaluation of both CT and MR imaging.

The skeletal changes of severe hyperparathyroidism, known as osteitis fibrosa cystica, are now rarely encountered, because hyperparathyroidism is currently being diagnosed and treated at an early stage. Herein, a case of brown tumor of the sternum is reported; our report adds histologic data on this type of tumor to the literature.

Brown tumor is a focal lesion differentiated from other giant-cell tumors by the presence of hyperparathyroidism. Treatment of brown tumors must be initially directed towards correcting the hyperparathyroidism. Tumor regression may occur with resolution of the hyperparathyroidism.

Brown Tumor and Secondary Hyperparathyroidism
Archives of Ophthalmology, 1991Brown tumor is a focal, bony lesion of hyperparathyroidism that results from parathyroid hormone on bone increasing osteoclastic activity with bone resorption and trabecular fibrosis. This leads to microfractures and hemorrhage and the appearance of brown tumors, which are seen most commonly in primary hyperparathyroidism and less frequently in ...
