Oncogenic osteomalacia is an uncommon syndrome characterized by phosphaturic tumours that produce mineral metabolism abnormalities. Head and neck is the second most frequent location of these tumours. We describe a case of a phosphaturic mesenchymal tumour in the infratemporal fossa that caused oncogenic osteomalacia, resolved by means of surgical excision.

UI MeSH Term Description Entries
D007015 Hypophosphatemia, Familial An inherited condition of abnormally low serum levels of PHOSPHATES (below 1 mg/liter) which can occur in a number of genetic diseases with defective reabsorption of inorganic phosphorus by the PROXIMAL RENAL TUBULES. This leads to phosphaturia, HYPOPHOSPHATEMIA, and disturbances of cellular and organ functions such as those in X-LINKED HYPOPHOSPHATEMIC RICKETS; OSTEOMALACIA; and FANCONI SYNDROME.
