Background Adrenocortical cancer (ACC) is a rare malignancy. In the absence of metastatic disease, the suspicion of ACC is based on size and radiological appearance. The aim of this study was to analyse the long-term outcome of patients with large adrenal cortical tumours (>8 cm).

Context: Genetic abnormalities, such as those of multiple endocrine neoplasia type 1 (MEN1) and Cyclin D1 (CCND1) genes, occur in <50% of nonhereditary (sporadic) parathyroid adenomas. Objective: To identify genetic abnormalities in nonhereditary parathyroid adenomas by whole-exome sequence analysis. Design: Whole-exome sequence analysis was performed on parathyroid adenomas and leukocyte DNA samples from 16 postmenopausal women without a family history of parathyroid tumors or MEN1 and in whom ...

A 56-year-old man was found to have an adrenal incidentaloma on a CT scan of the abdomen. Clinically and biochemically, the mass was not functional. MRI scan revealed a heterogeneously enhancing, T2-hyperintense, right-sided adrenal mass (4.5×6.5 cm). Meta-iodo-benzylguanidine scan was normal, making a diagnosis of pheochromocytoma unlikely. As the mass was larger that 4 cm, it was excised and histopathological examination revealed a rare, composite tumour: benign adrenal adenoma with haemangiom...

Background Concordant parathyroid localization with sestamibi and ultrasound scans allows minimally invasive parathyroidectomy (MIP) to be performed in patients with non-familial primary hyperparathyroidism (PHPT).

Background Functional imaging using 123I-meta-iodo-benzyl-guanetidine (MIBG) scintigraphy has alleged 100% specificity for phaeochromocytoma (PHAEO). Its benefit in patients with biochemical diagnosis of PHAEO is arguable when cross-sectional radiology can demonstrate the side–size of the adrenal tumours.

Primary hyperparathyroidism is hereditary in 10% of patients. This article describes a patient with familial isolated hyperparathyroidism (FIHP) caused by a novel MEN1 missense mutation. The genetics, differential diagnosis and management of hereditary hyperparathyroidism are illustrated.
