Abstract
BK polyomavirus-associated carcinoma of the kidney or bladder following cardiac or pulmonary transplantation has been reported in only 7 individuals, all but 1 being adults. We now report 2 additional pediatric patients, the first having received a lung transplant at the age of 21 months and developing a renal cell carcinoma at 14 years, and the second receiving a heart transplant at 20 months and developing a bladder urothelial carcinoma at 21 years.
