Correlation of these findings with clinical features is required for diagnosis. Treatment with antiviral agents appears to be the most effective. We report the occurrence of TS in a 20-month-old girl with multivisceral transplantation due to short-bowel syndrome secondary to intestinal atresia and gastroschisis. The patient was treated with cidofovir 1% cream, with significant improvement and without any adverse effects. We describe the youngest patient, to our knowledge, with TS.
