Treatment of Multifocal Primary Cutaneous B-Cell Lymphoma: A Clinical Follow-Up Study of 29 Patients
1999
PURPOSE: Although patients with primary cutaneous B-cell lymphoma (CBCL) and localized skin lesions are generally treated with radiotherapy and have an excellent prognosis, the clinical behavior and optimal treatment of CBCL presenting with multifocal skin lesions are less well defined. In this study, we evaluated the clinical behavior of and results of treatment for multifocal CBCL in 29 patients, and we formulated therapeutic guidelines. PATIENTS AND METHODS: The study group included 16 patients with primary cutaneous follicular center-cell lymphoma (PCFCCL), eight with primary cutaneous immunocytoma (PCI), and five with primary cutaneous large B-cell lymphoma presenting on the legs (PCLBCL of the leg). RESULTS: Only one of the 24 patients with multifocal PCFCCL or PCI developed extracutaneous disease, and no patient died from lymphoma (median follow-up, 54 months). In patients with PCFCCL, treatment with either multiagent chemotherapy (nine patients) or radiotherapy directed toward all skin lesions (fi...
