Abstract:
An 80-year-old woman with a history of bilateral breast cancer was referred for investigation of hypercalcaemia, initially suspected to be bone metastasis. Sestamibi scan revealed the cause to be a large parathyroid adenoma which was then removed. Hypercalcaemia is the most frequent metabolic complication of breast cancer. Primary hyperparathyroidism is one of the most frequent causes of benign hypercalcaemia, but is often not considered in oncology patients. This case illustrates the importance of considering two primary pathologies.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
The Parathyroid Glands
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
