AMA Am J Dis Child. 1958;96(3):374-375. doi:10.1001/archpedi.1958.02060060376015

We are adding 1 more case of simple renal cyst to the 21 recorded cases in children as reported by DeWeerd and Simon.1 In an excellent review of this condition, they emphasized the congenital nature of the lesion. There are no further reports in the English literature to date.

Report of Case  A 2½-year-old white boy was first admitted to the hospital on Sept. 4, 1956. One month prior to admission his mother noticed a large swelling involving the left upper quadrant of the abdomen. Physical examination confirmed this finding, and he was admitted for investigation. The past and family histories were noncontributory.Examination at admission revealed a fixed nontender smooth mass occupying the left upper quadrant and left flank. The rest of the examination was essentially negative except for a small umbilical hernia.Laboratory data were as follows: hemoglobin, 14 gm.; erythrocytes, 4,160,000 per cubic millimeter; leukocytes, 6700
