Hypercalcemia in association with mesoblastic nephroma: report of a case and review of the literature

摘要

Hypercalcemia, often associated with certain types of adult tumors, has also been described in pediatric neoplasms. In childhood, the more common associations include lymphoma, leukemia, rhabdomyosarcoma and rarely neuroblastoma. However, recently, several infants with hypercalcemia were described having renal tumors without bone metastases. The following is a case report of a 2-month-old infant who presented with severe hypercalcemia and a large right-sided abdominal mass, which at surgery was diagnosed as a cellular mesoblastic nephroma.
