A case of cutaneous large B-cell lymphoma of the legs appearing as chronic venous ulcerationDOI: 10.4081/hr.2012.e6 Keywords: Primary cutaneous B cell lymphoma , B cell lymphoma of the leg , Immunophenotype , Therapy Abstract: We report here a case of a woman with a cutaneous large B-cell lymphoma of the legs. She had a plaque lesion, superficially ulcerated and necrotized with tumorous borders situated on the posterior side of the right leg and two red or bluish-red nodular lesions. A skin biopsy from both nodular and plaque lesion showed a diffuse infiltrate of atypical large B cells CD20+ and CD79a+, spanning epidermis, dermis and subcutaneous tissue. A therapeutic approach containing anti-CD20 monoclonal antibody (rituximab) was suggested.
