Lymphomatoid Papulosis/Pityriasis Lichenoides in Two Children

Two children developed lymphomatoid papulosis/pityriasis lichenoides at ages 3 and 6 years. Follow-up continued for 13 years in the former patient and for 6 years in the latter. Both children now have continuing low-grade disease activity requiring in the one case topical corticosteroid therapy and in the other low-dose systemic steroid therapy. These children are reported to emphasize to pediatricians, pediatric pathologists, and hematologists that pseudolymphomatous conditions can exist in young children and do not require potent cytotoxic therapy. In both of our patients, the initial diagnosis was thought to be an aggressive lymphoma.
