Primary hyperparathyroidism: Brown tumor in hand, foot, and femur

Abstract

Abstract Introduction Bone fractures due to primary hyperparathyroidism/brown tumor can still be seen today, albeit rarely. Clinical Case A 47-year-old migrant woman had a right femur fracture after a simple fall. The patient's laboratory values were found as calcium 16.3 (8.4–10.2) mg/dl, phosphorus 2.5 (3.2–5.5) mg/dl, Alkaline phosphatase: 1131 (40–150) U/L, Parathormone 1711 (15–65) pg/ml. A 40×30 mm parathyroid adenoma was detected in the lower left side of the patient, who was suspected of having primary hyperparathyroidism. Parathyroid adenoma in the same localization was also observed in neck tomography. At the same time, a brown tumor was detected on the hand and foot bones. The patient underwent a left parathyroid adenomectomy. Intravenous calcium infusion was given to the patient who developed hungry bone syndrome in the postoperative period. Calcium, phosphorus, and parathormone levels of the patient who was treated for hungry bone syndrome returned to normal. Later on, the patient underwent a right femoral prosthesis operation. Conclusion Brown tumor is often seen in the bones of the hands, feet, and long bones.
