Hypercalcemia Associated With Transitional Cell-Carcinoma Without Bone Metastases - Description Of 2 Cases

Two cases of hypercalcemia associated with transitional cell carcinoma and negative bone scan are described. In both cases hypercalcemia appeared while there was evidence of tumor spread. Although hypercalcemia was controlled, both patients died shortly thereafter. Hypercalcemia rarely occurs in transitional cell carcinoma and its appearance may suggest spreading of the tumor and poor prognosis.
