OBJECTIVETo investigate the diagnosis and surgical treatment of parathyroid carcinoma.
METHODSThe clinical data of 9 cases of parathyroid carcinoma treated from January 1967 to December 2009 was analyzed retrospectively with the review of related Chinese literatures.
RESULTSParathyroid carcinoma accounted for 8.9% (8/90) of all patients with primary hyperparathyroidism in our hospital, and the other one case was transferred from another hospital. Of the patients, 8 cases were found with primary hyperparathyroidism. Primary surgery was carried out with small incision: 5 patients underwent en bloc resection, among which, 3 cases received central lymph node dissection; 2 patients received simple parathyroidectomy; one case underwent palliative tumor resection. The case from another hospital received subtotal thyroidectomy. Considering preoperative, intraoperative data and frozen sections pathology, all patients were diagnosed as parathyroid carcinoma. Nine patients were followed-up for 1 - 14 years, no recurrence occurred, and the patient received palliative resection died from carcinoma two years after the operation. In previous Chinese literatures and this group, there were total 146 patients reported as parathyroid carcinoma. Those patients were diagnosed through routine histopathology, accounted for 1.8% - 11.5% of patients with primary hyperparathyroidism.
CONCLUSIONSThe diagnosis of parathyroid carcinoma is established according to severe hypercalcemia, clinical features, subset B-ultrasound and Tc(99m)-sestamibi scanning, intraoperative finding of adherence to close structures and histopathology. The initial surgical procedure of choice is en bloc resection of the tumor by minimally invasive small incision, including adjacent structures and ipsilateral thyroidectomy. The prognosis is favorable after the operation.

Multiple endocrine neoplasia type 1 (MEN1) syndrome includes varying combinations of endocrine and non-endocrine tumors. There are also a considerable number of atypical MEN1 syndrome. In this case, a 68-yr-old woman was referred to the Department of Endocrinology for hypercalcemia. Five years ago, she had diagnosed as primary hyperaldosteronism and now newly diagnosed as parathyroid hyperplasia with laboratory and pathologic findings. Hurthle-cell thyroid cancer was also resected during the parathyroid exploration and small meningioma was found on brain MRI. Her general condition has markedly improved and her adrenal mass and meningioma are being closely observed now. We could find the loss of heterozygosity of the MEN1 locus in parathyroid glands, suggesting a MEN1-related tumor, but not a germline mutation. Considering a variety of phenotypic expression and a limitation of current molecular analysis, periodic follow up will be needed in patients with a MEN1-like phenotype.
