Parathyroid carcinoma.
J Coll Physicians Surg Pak Jan ;22(12):789-91.

Parathyroid carcinoma is a rare cause of hypercalcaemia due to primary hyperparathyroidism. Ninety five percent of parathyroid carcinomas are functional tumours. Surgery is the only potential curative treatment. This is a case of a 53 years lady, who presented with pathological fracture of femur, hypercalcaemia, deranged renal functions, change in voice, difficulty in swallowing and markedly raised parathormone levels. Doppler ultrasound localized an irregular mass at right lower gland. SESTAMIBI scan showed probability of adenoma in the region of right lower thyroid pole. Intra-operatively, tumour was found stuck to esophagus and right recurrent laryngeal nerve passing through it. Enlarged parathyroid gland was removed in toto along with the recurrent laryngeal nerve, right thyroid lobe and its isthmus.
