Supra-Acetabular Brown Tumor due to Primary Hyperparathyroidism Associated with Chronic Renal Failure by Rosaria M. Ruggeri, Emanuele Calamoneri, Antonia Russo, Alessandro Sindoni, Baldassarre Mondello, Maurizio Monaco, Michele A. Rosa, Sergio Baldari, Salvatore Benvenga, Alfredo Campennì, Francesco Trimarchi

“…Serum intact PTH was elevated (1020 pg/ml; normal values, 12 62 pg/ml), but her serum calcium was normal (total = 9.4 mg/dl, nv 8.5–10.5; ionized = 5.0 mg/dl, nv 4.2–5.4) due to the coexistence of chronic renal failure. 99mTc-MIBI scintigraphy revealed a single focus of sestamibi accumulation in the left retrosternal location, which turned out to be an intrathoracic parathyroid adenoma at surgical exploration. After surgical removal of the parathyroid adenoma, PTH levels decreased to 212 pg/ml. …”

A Reference Finding Rarely Seen in Primary Hyperparathyroidism: Brown Tumor by F. Mantar, S. Gunduz, U. R. Gunduz

“…We present a male patient presented with a massive painless swelling in the left maxilla as the first manifestation of primary hyperparathyroidism due to a parathyroid adenoma. Parathyroidectomy was performed, and there was a regression of the bone lesion, without the need of performing other local surgical procedures.…”

Bone and Mineral Metabolism in Patients with Primary Aldosteronism by Luigi Petramala, Laura Zinnamosca, Amina Settevendemmie, Cristiano Marinelli, Matteo Nardi, Antonio Concistrè, Francesco Corpaci, Gianfranco Tonnarini, Giorgio De Toma, Claudio Letizia

“…Aldosterone excess may influence mineral homeostasis, through higher urinary calcium excretion inducing secondary increase of parathyroid hormone. Recently, in a cohort of PA patients a significant increase of primary hyperparathyroidism was found, suggesting a bidirectional functional link between the adrenal and parathyroid glands. …”
