title: Lymphomatoid papulosis and Ki-1+ anaplastic large cell lymphoma occurring concurrently in a pediatric patient.
abstract: Lymphomatoid papulosis (LyP) is a benign, self-healing, papular eruption that can wax and wane over the course of time. Transformation to T-cell lymphoma has been well documented in 10% to 20% of adults with LyP, but there are have been no cases reported in patients younger than age 26 years. We describe the first pediatric patient, a 16-year-old girl, who had clinical features of LyP and concurrently was found to have a lesion diagnosed as Ki-1+ anaplastic large cell lymphoma. After treatment with chemotherapy, she has been in continuous remission for 16 months.
