LT and HSCT are now potentially curative treatments for many medical conditions. Dermatologic manifestations are one of the sequelae after transplantation. To study the prevalence and associated risk factors of dermatologic manifestations after pediatric LT and HSCT. A 20-year retrospective cohort study was conducted in children, aged ≤15 years, who received LT or HSCT from January 1, 1997, to December 31, 2017. Medical records were reviewed for data collection until December 31, 2018. A total of 70 LT and 51 HSCT recipients were included. The percentages of overall dermatologic manifestations after LT and HSCT were 64.3% and 64.7%, respectively. Viral infection was the most common manifestation in both groups, with mucocutaneous HSV infection as the most prevalent. One HSCT recipient developed leukemia cutis. GVHD was revealed in 27.5% of HSCT recipients. Impetigo and xerosis were significantly observed in patients using azathioprine and prednisolone. Approximately two-thirds of pediatric LT and HSCT recipients experienced dermatologic manifestations, potentially associated with immunosuppressive agents. Thus, regular skin examination and optimized immunosuppression would be beneficial in these recipients.
