Overview
Hodgkin's lymphoma (HL) may be classified according to World Health Organization (WHO) into two major subgroups: nodular lymphocyte predominant and classic Hodgkin's lymphoma. classic Hodgkin's lymphoma is further divided into four subtypes: nodular sclerosis classic HL (NSHL), mixed cellularity classic HL (MCHL), lymphocyte rich classic HL (LRHL), and lymphocyte depleted classic HL (LDHL).
Classification
Hodgkin's lymphoma may be classified according to World Health Organization (WHO) into two major subgroups based upon the appearance and immunophenotype of the tumor cells:[1]
- Nodular lymphocyte predominant Hodgkin's lymphoma
- Classical Hodgkin's lymphoma
Classic Hodgkin's lymphoma is further divided into four subtypes:
- Nodular sclerosis classic HL (NSHL)
- Mixed cellularity classic HL (MCHL)
- Lymphocyte rich classic HL (LRHL)
- Lymphocyte depleted classic HL (LDHL)
| Name | Description |
|---|---|
| Nodular sclerosing | 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 | 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. |
- According to the Ann Arbor Staging System[2], there are 4 stages of Hodgkin's Lymphoma based on clinical features and findings on imaging. Each stage is assigned one letter and one number that designate the number of involved lymph node regions and the presence/absence of symptoms. The stages of Hodgkin's Lymphoma are shown in the table below:
| Hodgkin's Lymphoma | |
| Stage | Definition |
| I | |
| II | |
| III | |
