Peripheral T-cell-lymphomas (PTCL) other than ALK-negative and CD-30 positive anaplastic large cell lymphoma were ALK-positive anaplastic large cell lymphoma (N = 56), anaplastic large cell lymphoma (T and null cell types) (N = 12), primary cutaneous anaplastic large cell lymphoma (N = 17), anaplastic large cell lymphoma without T- and B-cell markers (N = 4) and anaplastic large cell lymphoma not specified (N = 11). Here, TNFRSF8 is linked to anaplastic large cell lymphoma.
