title: Polycythemia secondary to multiloculated renal cyst in a child.
abstract: Polycythemia has been reported in association with a variety of pediatric renal neoplasms. The authors present the case of a 10-year-old boy with polycythemia and elevated erythropoietin that resolved after resection of a multiloculated renal cyst. This case also is unusual in the small size of the lesion, 0.5 cm in greatest dimension.
