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.
Hodgkin lymphoma (HL) is a type of lymphoma in which cancer originates from a specific type of white blood cell called lymphocytes, where multinucleated Reed–Sternberg cells (RS cells) are present in the patient's lymph nodes.
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 cells lack expression of these markers, but express B cell markers like CD20, CD22, and CD79a and also express the common leukocyte antigen CD45, which is ...
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]
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.
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 ...
