In this report, we present a case of CD30+ peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) that emerged one month after the completion of BV-CHP therapy for anaplastic large cell lymphoma (ALCL) and which responded to retreatment with BV monotherapy. Here, TNFRSF8 is linked to mature T-cell and NK-cell non-Hodgkin lymphoma.
