  Osteomalacia
Osteomalacia is a disease in which insufficient mineralization leads to a softening of the bones.
Osteomalacia can occur because of reduced exposure to sunlight (which, after touching the skin, causes the body to make vitamin D), insufficient intake of vitamin D–enriched foods (like vitamin D–fortified milk), or improper digestion and absorption of food with vitamin D (as in bowel disorders such as lactose intolerance or celiac disease).
Osteomalacia should not be confused with osteoporosis, which is a disease of normal mineralization but decreased amounts of bone.

 THE MERCK MANUAL OF GERIATRICS, Ch. 49, Metabolic Bone Disease
Osteomalacia should be suspected in patients with typical ribbonlike cortical lucencies (pseudofractures) that are found with plain x-rays and in patients in whom the serum Ca level is low or low-normal, the serum phosphorus level is low, and the serum alkaline phosphatase and parathyroid hormone levels are high.
Osteomalacia (analogous to rickets in children) is relatively rare in the elderly, although deficiency of vitamin D and Ca is common.
Osteomalacia due to vitamin D deficiency should be suspected when the serum Ca level is low or low-normal, the serum phosphorus level is low, and the serum alkaline phosphatase and PTH levels are high.

Osteomalacia is a serious disease that softens bones, often causing incapacitating pain and fracture.
We conclude that the osteomalacia that occurs in dialysis patients is due to multiple factors that are removed by deionization.
Thus, the progression of osteomalacia appears to be the main reason for the increasing incidence of bone pain and pseudofractures which we and others have observed in patients on chronic dialysis for periods longer than 6 months.

 Phosphaturic Mesenchymal Tumor/Oncogenic Osteomalacia
Oncogenic osteomalacia is an unusual and rare clinicopathologic syndrome characterized by mesenchymal tumors that apparently produce osteomalacia and biochemical abnormalities consisting of hypophosphatemia, normocalcemia, and increased levels of alkaline phosphatase.
Tumor-induced (oncogenic) osteomalacia is a rare clinicopathologic entity in which the clinical signs and symptoms of osteomalacia and the specific laboratory abnormalities of hypophosphatemia, hyperphosphaturia, and low serum levels of 1,25(OH)2 vitamin D are associated with the finding of a neoplastic process in the patient.
Oncogenic osteomalacia is an uncommon syndrome characterized by bone pain, proximal muscle weakness, hypophosphatemia, hyperphosphaturia, and a low concentration of 1,25-dihydroxyvitamin D. This syndrome is induced by a tumor, usually benign, of mesenchymal origin and resolves after its excision.
