Three children with CD30 cutaneous anaplastic large cell lymphomas bearing the t(2;5)(p23;q35) translocation

Since its discovery in CD30(+) anaplastic large cell lymphomas, the t(2;5)(p23;q35) translocation has shown a high degree of association with nodal disease, younger patient age, and better prognosis. Furthermore, primary cutaneous CD30(+) anaplastic large cell lymphomas rarely manifests the t(2;5) translocation. We present three cases of this disease that occurred in children, bore the t(2;5) translocation, and had excellent outcomes, but presented cutaneously. Two of these lesions were primary skin lymphomas. Review of the available literature in conjunction with these three cases suggests that the t(2;5) translocation may be more strongly associated with younger patient age and favorable outcomes rather than nodal versus cutaneous site of presentation.
