From 1986 to 1999 we operated on 963 patients with primary hyperparathyroidism (pHPT).
Parathyroid carcinoma was diagnosed clinically and histologically in four patients (0.4%). In two of these patients diagnosis of parathyroid cancer was delayed by misinterpretation of the histopathology leading to an autotransplantation of malignant parathyroid tissue in one case. In two patients multivisceral surgery was performed: beside thyroidectomy, neck dissection, tracheal wall resection and resection of the muscular layer of the oesophagus one patient received oesophagectomy and gastric transposition and one patient a lung wedge resection. Both patients had a temporary palliation of tumour-associated symptoms after multivisceral surgery. The first patient died 2 years after oesophagectomy and 12 years after primary diagnosis from local tumour recurrence and cachexia. The second patient is living with tumour recurrence presenting a serum calcium level of 4.2 mmol/l (normal range 2.0 to 2.5 mol/l) and multiple brown tumours 2 years after lung resection and 6 years after the primary diagnosis.
We conclude that parathyroid carcinomas, being difficult to diagnose, warrant radical surgery, including multivisceral resection to prolong survival and reduce tumour and hypercalcaemia associated symptoms.
