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.
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 ...
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]
Reed–Sternberg cells display a characteristic pattern of sialyl-Lewis X positivity, with membranous staining combined with staining of the Golgi apparatus. Immunohistochemical panels for the diagnosis of Hodgkin's disease typically employ CD15 along with CD30 and CD45 ; the latter does not stain Reed–Sternberg cells, but does stain almost ...
Owl's eye appearance, also known as owl's eye sign, is a pattern used in the medical field to describe cells (or cell attributes) that resemble the shape of an actual owl's eye. Using the techniques of histology and radiology , microscopes and other medical imaging are used to locate this pattern of "owl's eye" shaped cells.
Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).
