Primary cutaneous B-cell lymphomas (CBCL) represent approximately 20-25% of all primary cutaneous lymphomas. With the advent of the World Health Organization-European Organization for Research and Treatment of Cancer (EORTC) consensus classification for cutaneous lymphomas in 2005, uniform terminology and classification for this rare group of neoplasms was introduced. However, staging procedures and treatment strategies still vary between different cutaneous lymphoma centres, which may be due to the fact that consensus recommendations for the management of CBCL have never been published. Based on an extensive literature search and discussions within the EORTC Cutaneous Lymphoma Group and the International Society for Cutaneous Lymphomas, the present report aims to provide uniform recommendations for the management of the three main groups of CBCL. Since no systematic reviews or (randomized) controlled trials were available, these recommendations are mainly based on retrospective studies and small cohort studies. Despite these limitations, there was consensus among the members of the multidisciplinary expert panel that these recommendations reflect the state of the art management as currently practised in major cutaneous lymphoma centres. They may therefore contribute to uniform staging and treatment and form the basis for future clinical trials in patients with a CBCL. of (11%) with a (FCL) first presenting in the as compared to two of 82 patients with a marginal zone lymphoma (MZL) In nine of these 22 the only evidence of extracutaneous disease. The 5-year overall and disease-specific survivals of these nine patients were 44% and 63%, respectively, compared to 84% and 95% in 157 patients without extracutaneous disease. indicate that bone marrow examination should be considered as an essential part of staging procedures in patients with a FCL first presenting in the skin and that, from a clinical point of view, bone marrow examination appears to have limited value in
