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.
Classic Hodgkin lymphoma (excluding nodular lymphocyte predominant Hodgkin lymphoma) can be subclassified into four pathologic subtypes based upon Reed–Sternberg cell morphology and the composition of the reactive cell infiltrate seen in the lymph node biopsy specimen (the cell composition around the Reed–Sternberg cell(s)). Presence of EBV ...
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 ...
EBV is found in 30% to 50% of HL cases, but occurs in ~90% of NSHD and MCHD but ≤10% of LRHD, LPHD, or NLPHD cases. HL involves the infiltration of T cells, B cells, macrophages, eosinophils, fibroblasts, and Reed–Sternberg cells (HRS cells, also termed Hodgkin Reed-Sternberg cells) into lymphoid and other tissues.
Hodgkin lymphoma (HL) is one of the most common cancers that do not indicate AIDS, and since highly active antiretroviral therapy was introduced, its incidence has increased. It is a germinal center-derived cell that produces Hodgkin Reed–Sternberg (HRS) cells. [15] It is more common in immunocompromised individuals, especially those with HIV ...
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 ...
Second-most common form of Hodgkin lymphoma Many classic Reed–Sternberg cells and inflammation CD15, CD30 Most common in men, more likely to be diagnosed at advanced stages than the nodular sclerosis form Epstein–Barr virus involved in 70% of cases. Lymphocyte-rich; Lymphocyte depleted or not depleted; Nodular lymphocyte-predominant Hodgkin ...
CD30 is associated with anaplastic large cell lymphoma. It is expressed in embryonal carcinoma but not in seminoma and is thus a useful marker in distinguishing between these germ cell tumors. [8] CD30 and CD15 are also expressed on Reed-Sternberg cells typical for Hodgkin's lymphoma. [9]
