Abstract:
Oncogenic Osteomalacia syndrome is associated with mesenchymal tumours, caused by a protein secreted from tumours which inhibits tubular renal phosphate absorption and reduces 1,25 dihydroxy vitamin-D renal conversion. It manifests as osteomalacia with hypophosphataemia and hyperphosphaturia. Association of neurofibromatosis with oncogenic osteomalacia is unusual. We report a rare case of oncogenic osteomalacia with generalized neurofibromatosis which presented to us as pathological fracture.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
