Abstract
- Patients with lymphomatoid papulosis have an increased risk (approx. 5% to 20%) of developing a malignant lymphoma such as mycosis fungoides, anaplastic large cell lymphoma (ALCL) and Hodgkin's disease before, during, or after lymphomatoid papulosis occurs. However, it is very rare that lymphomatoid papulosis occurs after ALCL, especially in childhood. An 11-year-old boy who had been diagnosed with ALCL 3 years prior and treated with chemotherapy and peripheral blood stem cell transplantation developed multiple scaly papules on his trunk and both extremities. Histopathologic and immunohistochemical examination of the scaly papules revealed lymphomatoid papulosis. The patient was cured with narrow band UVB treatment and there has been no relapse in lesions 10 years later. We report a case of lymphomatoid papulosis following allogenic stem cell transplantation for ALCL.
