Reed–Sternberg cells are CD30 and CD15 positive except in the lymphocyte predominance type where they are negative, but are usually positive for CD20 and CD45. The presence of these cells is necessary in the diagnosis of Hodgkin lymphoma – the absence of Reed–Sternberg cells has very high negative predictive value.
Lymphocyte predominant (LP) ("popcorn") cells are present embedded in nodules consisting of B cells [10] and other reactive cells (mainly reactive T cells). [9] Reed-Sternberg and Hodgkin (RSH) cells are rarely seen, and immunohistochemistry shows a different pattern on the malignant cells; RSH cells typically express CD15 and CD30, whereas LP ...
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. [39]
Reed–Sternberg cell variants and inflammation, usually broad sclerotic bands that consist of collagen CD15, CD30 Most common in young adults, often arises in the mediastinum or cervical lymph nodes. Mixed cellularity Hodgkin lymphoma; Second-most common form of Hodgkin lymphoma Many classic Reed–Sternberg cells and inflammation CD15, CD30
It is composed of large tumor nodules with lacunar Reed–Sternberg cell (RS cells) surrounded by fibrotic collagen bands. [ citation needed ] The British National Lymphoma Investigation further categorized NSHL based upon Reed–Sternberg cells into "nodular sclerosis type I" (NS I) and "nodular sclerosis type II" (NS II), with the first ...
The adjacent micrograph shows a typical RS cell, surrounded by normal lymphocytes. RS cells are distinctively large and have multiple nuclei, as in his case, or one nucleus with two lobes. RS cells express CD30 cell surface protein (a member of the tumor necrosis factor receptor family) and CD15 (a blood group antigen carbohydrate on the cell ...
Type II PEL also tends to involve malignant plasmablasts, anaplastic cells, and/or Reed-Sternberg-like cells that have somewhat different expression patters of protein markers (e.g. the malignant cells in Type II PEL frequently express CD20 but often do not express CD30) and gene abnormalities (e.g. the malignant cells in Type II PEL more ...
T-cell/histiocyte-rich large B-cell lymphoma most commonly afflicts middle-aged (i.e. 49–57 years old) individuals but has been diagnosed in persons aged 4 [6] to 92 years. [2] The disease has a male predominance ranging between 1.7:1 [ 3 ] to 3:1 [ 2 ] in different studies.
