title: [Malignant lymphomas in spleen--morphology and microenvironment].
abstract: The different entities of malignant lymphomas in the spleen exhibit characteristic stage-dependent infiltration patterns which, in conjunction with cytologic findings, may be employed for diagnostic purposes. These infiltration patterns result from complex interactions between neoplastic and non-neoplastic splenic cell populations which are only incompletely understood. These interactions are governed by intrinsic properties of the involved cell populations, e.g. surface receptors, proliferation activity, cytokine production, immunocompetence etc., as well as by extrinsic factors, e.g. splenic microanatomy and the behavior of splenic immunocompetent and accessory cells which are responsible for the highly organized splenic microenvironments.
