Abstract:
Significant hypophosphatemia is commonly due to Vitamin D deficiency. Any sporadic onset of hypophosphatemia in adults warrants workup to identify alternate causes. Hypophosphatemia may also be the only manifestation of an occult malignancy. A high index of clinical suspicion can help diagnose such conditions in early stages. Prompt treatment of the cause can correct this biochemical abnormality. We describe a case report of a woman presenting with severe hypophosphatemia and osteomalacia, leading eventually to the diagnosis of a phosphaturic mesenchymal tumor of the temporo-occipital bone. Surgical resection of tumor led to normalization of the biochemical parameters as well as a complete clinical recovery.

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...

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
