Primary bone hyperparathyroidism

: The authors report the case of a 19-year-old girl with osteolytic bone lesions in whom primary hyperparathyreoidism caused by parathyroid gland adenoma was diagnosed. They emphasize necessity to be aware of a relationship of this rare condition to bone lesions that may be benign in appearance and may show ambiguous histological findings. The patient underwent excision of the adenoma and subsequent substitution therapy, which resulted in the healing of bone lesions.
