Pham-Ledard et al. [26] investigated the status of the immunoglobulin genes of primary cutaneous (pc) DLBCL, leg-type (lt) to see whether they could confirm that this process derives from germinal center-experienced B lymphocytes, as is suggested by the immunophenotype (BCL2+, MUM1+, BCL6 +/−). Here, BCL2 is linked to diffuse large B-cell lymphoma.
