An aggressive primary cutaneous B-cell lymphoma, usually involving the lower leg. It is composed of a generally monotonous proliferation of immunoblasts, or less frequently centroblasts, with few admixed reactive cells. This type of lymphoma occurs most often in elderly women who present with rapidly growing tumors, usually on one or both legs. Dissemination to extracutaneous sites is frequent. Treatment with combination chemotherapy is usually required.
Biomarker and diagnostic research for primary cutaneous diffuse large B-cell lymphoma, Leg type has been reported in the published literature.
6 clinical trials registered, 1 recruiting. Interventions under study include drug therapy, biologic therapy, procedural interventions, and other interventions. Pipeline includes 6 PHASE2. Research is primarily sponsored by academic and government institutions.
