Lymphomatoid papulosis (LyP) is a recurrent papulonodular skin disease affecting the trunk and extremities.1,2 In some patients, LyP may resolve spontaneously. However, in some patients skin lesions persist and, in approximately 10% of patients, may even progress into malignant lymphoma. In rare cases, LyP may occur in young adults or children. These young patients pose a most difficult therapeutic challenge, as therapies applied to patients with LyP, such as systemic administration of steroids or oral psoralens plus UVA (PUVA)3 are given to children very reluctantly.

A 6-year-old boy presented in May 1994 with multiple, large, erythematous, partially ulcerated nodules and nodes involving the trunk and extremities. Histopathologic assessment revealed a dense infiltrate that extended deeply into the reticular dermis that consisted of numerous atypical bizarre-shaped cells of different size. Immunophenotypic analysis demonstrated the presence of CD30+ cells. There were no signs of systemic involvement,
