Background: Parathyroid carcinoma (PC) is a rare cause of primary hyperparathyroidism (PHPT). Distinguishing PC from other tumours underlying PHPT can be difficult and sometimes malignant diagnosis can be made only after recurrence of the disease. Atypical parathyroid adenomas (APA) have similar histological features as PC but lack signs of invasive growth. The expression of somatostatin receptors (SSTR) 1–5 in parathyroid tumours, commonly expressed in other neuroendocri...

Introduction: In multiple endocrine neoplasia 1 (MEN1), the decreased life expectancy is related especially to pancreatic neuroendocrine tumors (panNETs). Timely diagnosis of potentially aggressive panNETs is the cornerstone of the follow-up in MEN1. Somatostatin receptor positron emission tomography (SSTR PET/CT) has a high accuracy in the detection of neuroendocrine tumors. The role of this imaging modality in early diagnosis and follow-up of MEN1-related panNETs is unclear....

Introduction and design: Parathyroid carcinoma (PC) is a rare endocrine malignancy and the diagnosis is difficult. As the incidence seems to be increasing, we examined all cases diagnosed in our country during years 2000–2011 and compared the results to those of atypical parathyroid (AA; n=28) and parathyroid adenomas (A; n=72). All tissue specimens were re-examined.Results: In 2000–2011, 32 patients were diagnosed with PC in ...
