Oncogenic osteomalacia is a rare metabolic bone disease characterized by phosphate leakage from the kidney and subsequent hypophosphatemia. It is caused by a phosphaturic factor produced by certain tumours. Removal of such tumours can completely cure the condition. Here, we report the case of a patient who was crippled with oncogenic osteomalacia. Extensive study revealed a tumour deeply locate...

Vitamin D is an important hormone that can be a role of bone and calcium metabolism in the human organ. Thus, vitamin D deficiency could contribute to the severity of metabolic bone disease. The osteomalacia, one of the metabolic bone diseases, is the softening of the bones caused by defective bone mineralization secondary to inadequate amounts of available phosphorus and calcium. We experience...

We present an HIV-infected woman in whom antiretroviral treatment with tenofovir disoproxil fumarate (TDF) induced severe skeletal pain, synovial effusions and multiple fractures secondary to a Fanconi syndrome with hypophosphatemia and osteomalacia. TDF interferes with the replication of mitochondrial DNA in the proximal tubules of the kidney, which can explain the delayed onset of this form o...

Although the relationship between rickets and vitamin D was recognized over 60 years ago it is only relatively recently that the metabolic pathway leading to the active form of vitamin D was recognized. We now understand that vitamin D in the form of one of its active metabolites is necessary for the maintenance of calcium homeostasis and we appreciate in part the mechanisms by which this is br...

patients had a syndrome resembling osteomalacia, 4 patients had vertebral crush fractures, while one patient had pseudo-fractures (Looser's zones). Chalmers (1965) recently described to the British Orthopaedic Association 25 cases, including the 2 reported below, which he had collected within the past 3 years. He feels that the condition is much commoner than is generally suspected. CASE REPORT...
