We experienced 2 elderly male Japanese patients with reddish skin tumors. The histology of the tumors in both patients showed TdT-positive LBL. The pathological cells did not express T-, B- or NK-markers, and no rearranged bands were shown for Ig-JH, TCR-Cβ, Jγ, Jδ1, and c-myc. In addition, no EBV-derived DNA was detected in either case. The cells were CD45, CD43, CD74, CD10 and HLA-DR positive in both cases, and one of the cases showed CD4, CD36, CD54, CD58 and CD86-positive plasmacytoid lymphoblasts, which appeared to be compatible with intermediate cells between human bone marrow lymphoid precursors and mature lymphoid dendritic cells. The cutaneous LBL in the 2 cases may, therefore, have been of pDC-precursor origin.}, pages = {693--698}, title = {Cutaneous lymphoblastic lymphoma of putative plasmacytoid denbritic cell-precursor origin; 2 cases}, volume = {26}, year = {2002} }
