Histopathologic examination revealed an acellular infiltration between the epidermis and dermis as well as dermal infiltrationwith large and atypical lymphoid cells which stained positive for CD20 (++), Bcl-6 (+), Bcl-2 (+), Pax-5 (+), Ki-67 (50％-75％+ ), C D79a (+) , MUM-1 ( + ) but negative for CD10. The patient was diagnosed with primary cutaneous large B-cell lymphoma, leg type and treated with anti-CD20 monoclonal antibody and CHOP regimen. Thereafter, his condition improved.
