B-cell lymphomas represent approximately 20% to 25% of primary cutaneous lymphomas. Within this group, most cases (>99%) are encompassed by 3 diagnostic entities: primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma, and primary cutaneous diffuse large B-cell lymphoma, leg type. In this article, the authors present clinical, histopathologic, immunophenotypic, and molecular features of each of these entities and briefly discuss the rarer intravascular large B-cell lymphoma.
B细胞淋巴瘤约占原发性皮肤淋巴瘤的20%至25%。在这一类别中，大多数病例（>99%）包含在3种诊断实体中：原发性皮肤边缘区淋巴瘤、原发性皮肤滤泡中心淋巴瘤和原发性皮肤弥漫性大B细胞淋巴瘤，腿部型。在本文中，作者介绍了这些实体各自的临床、组织病理学、免疫表型和分子特征，并简要讨论了较为罕见的血管内大B细胞淋巴瘤。
