Abstract


Atypical parathyroid adenoma is among the tumors diagnosed difficultly and including some histological features of parathyroid carcinoma. In literature, no definite criteria have been considered to be present to distinguish atypical parathyroid adenoma preoperatively from parathyroid carcinoma. A 65-year-old woman was admitted to our clinic with complaints of arthralgia, myalgia, fatigue and loss of appetite. She had severe hypercalcemia (serum calcium 17.2 mg/dL) and hypophosphatemia (serum phosphate 1.9 mg/dL) along with an elevated intact parathyroid hormone level of 879 pg/mL. Renal functions were within normal limits. The patient was administered with intravenous hydration and diuretic treatments because of severe hypercalcemia. Six sessions of hemodialysis were performed. In neck ultrasonography, multinodular goitre was detected. Tc- 99m sestamibi scintigraphy revealed a focal involvement at the middle-inferior region of left thyroid lobe. Neck magnetic resonance imagination revealed a nodular lesion in size of 22 × 14 mm at the posterior region of left thyroid lobe. Parathyroidectomy guided by intraoperative gamma probe was performed. The lesion was histopathologically consistent with atypical parathyroid adenoma. In the postoperative period, serum calcium and intact parathyroid hormone levels were decreased as levels of 7 mg/dL and 42.6 pg/mL, respectively. We reported an atypical parathyroid adenoma accompanied by severe hypercalcemia and hyperparathyroidism.
