Summary
The existing scientific literature has not drawn a link between severe hypocalcaemia and its role in recalcitrant peripheral oedema. This phenomenon is particularly relevant in oncological and geriatric medicine as bone strengthening but serum calcium-lowering agents such as bisphosphonates and denosumab are used for osteoporosis and/or bone metastasis. This case report, through metastatic prostate cancer in a 66-year-old man with bone metastasis being treated with a monoclonal antibody denosumab, proposes the mechanism of hypocalcaemic oedema as being akin to calcium deprivation such as those induced by calcium channel antagonism. It demonstrates the importance of calcium supplementation as a concurrent treatment while patients are on these osteoclast inhibiting agents.
