Definition: Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a distinct type of Hodgkin lymphoma (HL) representing approximately 5% of all HL cases.

Clinical, morphologic, immunophenotypic, and molecular features set NLPHL apart from other types of HL, the latter collectively referred to as classical HL.

NLPHL is characterized by expansile nodules composed of sparse, relatively large neoplastic cells, referred to as lymphocytic and/or histiocytic (L&H) cells, intermixed with numerous reactive lymphocytes and a variable number of histiocytes.

The L&H cells are CD20-positive cells that carry immunoglobulin gene rearrangements with somatic hypermutations and, therefore, are thought to be derived from follicular center B cells.

Most patients with NLPHL present with localized lymphadenopathy, either stage I or II disease, and have an excellent prognosis with at least 80% overall survival at 10 years.

According to the recent World Health Organization classification and the European Task Force on Lymphoma, the diagnosis of NLPHL requires identification of a nodular growth pattern that may or may not be associated with a diffuse pattern.

The biologic significance of a diffuse component in NLPHL, particularly if this component is substantial, is not known. However, a purely diffuse form of LPHL is very rare, as most cases are now classified as either T-cell/histiocyte-rich large B-cell lymphoma (T/HRLBCL), a variant of diffuse large B-cell lymphoma, or classical HL. As diffuse areas in NLPHL resemble T/HRLBCL morphologically and immunophenotypically, many pathologists think that large diffuse areas in NLPHL may be a sign of transformation to a higher-grade neoplasm.
