HISTORY AND CLINICAL FINDINGS: A 49-year-old woman presented with increased bone and muscle pain of the left thigh and also of the left ribs since 1 1/2 year. 2 osteolytic regions on the left proximal femur were punctured but no tumour-like changes were found.
INVESTIGATIONS: Laboratory tests showed a severe hypophosphataemia (0.33 mmol/l), increased serum alkaline phosphatase activity and moderate elevated parathyroid hormone. Renal loss of phosphate was measured under phosphate substitution. The bone mineral density (DXA) was decreased. With octreotid scintigraphy a somatostatine receptor positive tumour was detected on the right proximal thigh and magnetic resonance scanning confirmed localization of the tumour.
TREATMENT AND COURSE: Treatment with oral phosphate and calcitriol improved the complaints presently. After total removal of a mesenchymal tumour, normalization of serum phosphate occurred and the patient did not require any medicine and did not have complaints anymore.
CONCLUSION: In a case of uncertain hypophosphataemic osteomalacia in adults it is essential to search for a tumour after exclusion of the rare differential diagnoses to enable a causal treatment of a potentially oncogenic osteomalacia.
