Parathyroid Hormone Related Peptide Hypercalcemia as a Presentation of Endometrial Clear Cell Carcinoma.

Hypercalcemia is a frequent complication of solid tumors and hematologic malignancies yet is only rarely associated with endometrial clear cell carcinoma. Here we report on a 70-year-old female who presented in the context of hip fracture and was incidentally found to have humoral hypercalcemia of malignancy secondary to endometrial clear cell carcinoma. This rare association makes endometrial cancer one of the differential diagnoses to be considered when assessing incidentally found symptomatic or asymptomatic hypercalcemia in the appropriate patient population.
