Definition

Diffuse large B-cell lymphoma (DLBCL) associated with chronic inflammation is a lymphoid neoplasm occurring in the context of long-standing chronic inflammation, and showing association with Epstein-Barr virus (EBV). Most cases involve body cavities or narrow spaces. Pyothorax-­associated lymphoma (PAL) is a prototypic form, and develops in the pleural cavity of patients with long-standing pyothorax.
