(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples). Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content.

Cancer Category / Type
Hodgkin's lymphoma
Cancer Sub-Classification / Subtype
N/A
Definition / Description of Disease
Variant of classical Hodgkin's lymphoma rich in lymphocytes, with expanded mantle zones, atrophic germinal centers, small number of Reed-Stenberg cells and classical Hodgkin's lymphoma immonophenotype [1][2].
Synonyms / Terminology
N/A
Epidemiology / Prevalence
It was the last subtype of classical Hodgkin lymphoma to be described and presents a low frequency, accounting for 3-5% of classical Hodgkin lymphomas [3]. Because of its rarity, the literature is limited on this type of lymphoma.
Clinical Features
The main clinical features are listed below [2][4][5].
| Signs and Symptoms | Older in age
Presentation at early stages are common Infrequent B symptoms (weight loss, fever, night sweats) Infrequent mediastinal involvement and bulky disease Usually good prognosis |
| Laboratory Findings | There is no characteristic finding in this condition. It can present with anemia, lymphocytopenia as a common condition of Hodgkin's lymphoma |
Sites of Involvement
Nodal disease with involvement of cervical lymph nodes. Mediastinal mass are rarely seen.
Morphologic Features
Lymphocyte-rich subtype presents intermediate characteristics between those of classical Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma [1][3]. The main feature is the predominance of small-lymphocytes in the background resembling nodular sclerosis classical Hodgkin Lymphoma,[6] but with T-cell populations surrounding the germinal centers [1]. Classic Reed Sternberg cells are found adjacent to germinal centers in approximately 89.5% of cases although they account for only a small fraction of the cells [4]. There are three growth patterns, the most frequent is the nodular pattern, with intact or atrophic germinal centers composed of small lymphoid cells displaying round nuclei [4] . Other growth patterns are interfollicular, composed of neoplastic cells forming small nodules with expansion to interfollicular areas and infiltration to adjacent mantle zones, and more rarely a diffuse growth pattern in which a germinal center is not seen [4].
Immunophenotype
Immunophenotype of lymphoma-rich classical Hodgkin lymphoma is shown in the table below [1][4].
| Finding | Marker |

| Negative (universal) | GCET-1 [1], J-chain [4] |
| Negative (subset) | CD20 (68%) [4], EBER (53%) [4], BCL6 (64%) [1], C-REL (75%) [1], REL-B (88%) [1], IgD (94%) [1], Blimp-1 (25%) [1] |
