Oxyphilic cell adenoma of parathyroid resulting in primary hyperparathyroidism and osteitis fibrosa cystica--a case report.

ABSTRACT

Adenomas of the parathyroid gland, the majority of which are of the solitary chief cell type, are the most frequent cause of primary hyperparathyroidism (pHPT). Parathyroid adenomas composed predominantly or exclusively of oxyphil cells are rare and most oxyphil cell adenomas of this organ remain clinically silent. We present here a case of hyperfunctioning oxyphil cell adenoma of the parathyroid gland resulting in pHPT, osteitis fibrosa cystica and simultaneous bilateral fractures upper shafts of femora.
