An unusual cause of gynaecomastia in a male.

Summary: Beta-human chorionic gonadotropin (βhCG) is normally produced by syncytiotrophoblasts of the placenta during pregnancy and aids embryo implantation. However, it is also secreted in varying amounts in non-pregnant conditions commonly heralding a neoplastic process. We present a case of 50-year-old man, who presented with bilateral gynaecomastia with elevated testosterone, oestradiol, suppressed gonadotropins with progressively increasing levels of human chorionic gonadotropin (hCG).

Papillary carcinoma of the thyroid in patients with primary hyperparathyroidism: Is there a link?

Primary hyperparathyroidism (PHPT) is present in up to 0.1% of the general population. The incidence is higher in women and increases with age.

A Novel Medical Treatment of Cushing's Due to Ectopic ACTH in a Patient With Neurofibromatosis Type 1.

A 64-year-old male presented with neurofibromatosis 1 and Cushing's syndrome. Clinically he was over weight, depressed with extensive skin bruising and hypertension. His 24 hours urinary metanephrines, urinary 5HIAA, gut peptides and chromgranin levels were normal.

A complex endocrine conundrum.

We describe a case of recurrent primary hyperparathyroidism, manifested as 3 metachronous parathyroid adenomata, in a 50 year-old woman who also had Hashimoto hypothyroidism, gastric gastrointestinal stromal tumour (GIST), cysts in liver and kidneys, 5 intestinal polyps (one of these a villous adenoma), diverticulitis and telangiectasia of lips. She did not have medullary thyroid carcinoma (MTC). Genetic analysis of the CDC73 gene [for Hyperparathyroidism-jaw tumor (HPT-JT)], MEN1 for Multiple Endocrine Neoplasia Type1, CDKN1B for MEN4, SDHB and SDHD for Paraganglioma/Pheochromocytoma susceptibility, VHL for von Hippel-Lindau Syndrome, BMPR1A and SMAD4 for Juvenile Polyposis Syndrome (JPS) (sequencing and MLPA), karyotype and array CGH (44 K) were all normal.
