Overview
Hodgkins lymphoma may be classified into 5 subtypes based on Reed-Sternberg cell morphology and the composition of the reactive cell infiltrate seen in the lymph node biopsy specimen.
Classification
Hodgkins lymphoma may be classified into 5 subtypes based on Reed-Sternberg cell morphology and the composition of the reactive cell infiltrate seen in the lymph node biopsy specimen.
| Name | Description |
|---|---|
| Nodular sclerosing Hodgkins lymphoma | Most common subtype and is composed of large tumor nodules showing scattered lacunar classical Reed–Sternberg cells set in a background of reactive lymphocytes, eosinophils, and plasma cells with varying degrees of collagen fibrosis/sclerosis. |
| Mixed-cellularity subtype | Common subtype and is composed of numerous classic Reed-Sternberg cells admixed with numerous inflammatory cells including lymphocytes, histiocytes, eosinophils, and plasma cells without sclerosis. This type is most often associated with Epstein–Barr virus (EBV) infection and may be confused with the early, so-called 'cellular' phase of nodular sclerosing classical Hodgkins lymphoma. |
| Lymphocyte-rich | Rare subtype, show many features which may cause diagnostic confusion with nodular lymphocyte predominant B-cell Non-Hodgkin's Lymphoma (B-NHL). This form also has the most favorable prognosis. |
| Lymphocyte depleted | Rare subtype, composed of large numbers of often pleomorphic Reed-Sternberg cells with only few reactive lymphocytes which may easily be confused with diffuse large cell lymphoma. Many cases previously classified within this category would now be reclassified under anaplastic large cell lymphoma |
