title: Cutaneous lymphomas and pseudolymphomas: newly described entities.
abstract: This chapter summarizes some recently described cutaneous lymphomas and pseudolymphomas with regard to their clinicopathological presentation, biological behavior and classification place. Among cutaneous lymphomas, the group of cytotoxic lymphomas, angioimmunoblastic T-cell lymphoma, intravascular lymphoma, hydroa-like lymphoma, marginal zone lymphoma, spindle-cell B-cell lymphoma, and B-cell lymphoma with a dermatomal distribution are presented. In the context of pseudolymphomas, cutaneous follicular lymphoid hyperplasia with monotypic plasma cells, pleomorphic reactions in molluscum contagiosum, and CD30+ reactions to parapoxvirus are discussed.
