Abstract
We present the case of a 6-month-old boy who was referred to us with the chief complaint
of intermittent painless gross hematuria. Computed tomography (CT) scan of the abdomen
showed a partially calcified soft-tissue mass that was located in the lower pole of
the right kidney and extended into the collecting system. Consequently, a partial
nephrectomy was performed. The resected specimen showed that the tumor was partially
calcified and occupied the renal pelvis. The histological findings suggested a diagnosis
of ossifying renal tumor of infancy (ORTI), only 16 cases of which have been reported
in the literature. The pathogenesis of this condition has not been well established.
ORTI should be considered in the differential diagnosis for infants with gross hematuria
and a calcified mass in the pelvicalyceal system.
