Overview
On gross pathology, white-grey, uniform, and enlarged lymphnodes are characteristic findings of Hodgkin's lymphoma. On microscopic histopathological analysis, Reed-Sternberg cells, reactive cell infiltrate, and complete or partial effacement of the lymph node architecture are characteristic findings of Hodgkin's lymphoma.
Pathophysiology
Hodgkin's lymphoma,[1] also known as Hodgkin lymphoma or Hodgkin's disease,[2] is a type of lymphoma, in which cancer originates from a specific type of white blood cells called lymphocytes.
Associated Conditions
Reports from countries like Honduras,[3] China,[4] Mexico,[5] Peru,[6] and Malaysia[7] suggest an association between EBV infection and Hodgkin's lymphoma, an association that is more evident in the pediatric population[8] and in the subtype of mixed cellularity.[9]
Gross Pathology
On gross pathology, affected lymph nodes (most often, laterocervical lymph nodes) are enlarged, but their shape is preserved because the capsule is not invaded. Usually, the cut surface is white-grey and uniform. In some histological subtypes (e.g. nodular sclerosis), the cut surface may have a nodular aspect.
Microscopic Pathology
Microscopic examination of the lymph node biopsy reveals complete or partial effacement of the lymph node architecture by scattered large malignant cells known as Reed-Sternberg cells (typical and variants) admixed within a reactive cell infiltrate composed of variable proportions of lymphocytes, histiocytes, eosinophils, and plasma cells. The Reed-Sternberg cells are identified as large often bi-nucleated cells with prominent nucleoli and an unusual CD45-, CD30+, CD15+/- immunophenotype. In approximately 50% of cases, the Reed-Sternberg cells are infected by the Epstein-Barr virus.

| Type of cell | Characteristics | |
|---|---|---|
| Classic | ||
| Reed-Sternberg cells (RSC) | Include large size (20–50 micrometres), abundant, amphophilic, finely granular/homogeneous cytoplasm; two mirror-image nuclei (owl eyes) each with an eosinophilic nucleolus and a thick nuclear membrane (chromatin is distributed close to the nuclear membrane). | |
| Variants | ||
| Hodgkin cells | (Atypical mononuclear Reed-Sternberg cell) have the same characteristics as Reed-Sternberg cells (RSC), but is mononucleated. | |
| Lacunar Reed-Sternberg cells | Are large, with a single hyperlobulated nucleus, multiple, small nucleoli and eosinophilic cytoplasm which is retracted around the nucleus, creating an empty space ("lacunae"). | |
| Pleomorphic Reed-Sternberg cells | Has multiple irregular nuclei. | |
| "Popcorn" Reed-Sternberg cells | (Lympho-histiocytic variant) is a small cell, with a very lobulated nucleus, small nucleoli. | |
| "Mummy" Reed-Sternberg cells | Has a compact nucleus with no nucleolus and basophilic cytoplasm. | |
