Abstract/OtherAbstract:
BACKGROUND: Primary cutaneous diffuse large B-cell lymphoma (PCDLBCL), leg type can eventually disseminate to extracutaneous sites including testes. In addition, patients with testicular lymphoma can develop specific skin involvement. OBJECTIVE: We sought to describe similarities between PCDLBCL, leg type and testicular B-cell lymphoma affecting the skin. METHODS: We report two cases with typical clinicopathological and immunophenotypical features of leg type lymphoma occurring simultaneously with a testicular B-cell lymphoma. We also report an additional case of PCDLBCL, leg type with secondary testicular involvement. RESULTS: All cases presented with typical red tumors exclusively located on the legs. Histologically, all cases showed a diffuse nonepidermotropic infiltrate composed of large blastic cells mainly centroblastic type. Phenotype showed strong positivity for Bcl-2, MUM-1, and FOXP1. Epstein-Barr virus stains and CD30 were negative in the 3 cases. In all cases the testicular infiltration showed the same pathological and phenotypical changes to those observed in the skin. LIMITATIONS: This was a retrospective case series study. CONCLUSION: Skin involvement by testicular B-cell lymphomas and PCDLBCL, leg type are indistinguishable on the basis of pathologic and immunophenotypical features, therefore specific investigation and clinic correlation are needed.
