Introduction

In the lung, primary lymphoproliferative disease represents a wide and overlapping spectrum of conditions from reactive polymorphous and polyclonal processes through to various entities of malignant lymphoma (Table 39.1) [1, 2]. The natural history of many of the conditions is variable with further heterogeneity recognized within distinct disease entities. Primary pulmonary lymphoproliferative diseases are rare, whereas secondary pulmonary lymphoma occurs in up to 20.5% of autopsy cases. The lung is a potential organ for tumor deposition in disseminated haematolymphoid disease.

Reactive pulmonary lymphoproliferative diseases encompass a spectrum of in ammatory and reactive lesions that are often diffcult to diagnose since they are diffcult to differentiate from other reactive and neoplastic entities. They includes

different clinicopathological patterns: intrapulmonary lymph nodes, nodular lymphoid hyperplasia, follicular bronchitis/ bronchiolitis, lymphocytic interstitial pneumonia (LIP).

Malignant lymphoproliferative diseases are distinguished in Hodgkin and non-Hodgkin lymphomas (HL and NHL), affecting B or T/NK cells. Malignant lymphoproliferative disorders may arise either as primary pulmonary lymphomas (PPL) within the lung parenchyma (without evidence of extrapulmonary involvement at diagnosis or in the subsequent 3 months) or as secondary pulmonary lymphomas spreading from systemic lymph nodes through the circulation and/or from neighboring sites (e.g., from mediastinal lymph nodes or thymus).

Malignant proliferative diseases more frequently occur in immunocompromised hosts, having in post-transplant and in HIV infected patients slightly different clinical and pathological profles from patients with autoimmune disorders or immune competent hosts.
