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.
Nodular lymphocyte predominant Hodgkin lymphoma; Micrograph of a lymph node biopsy showing nodular lymphocyte predominant Hodgkin lymphoma, with the Reed–Sternberg cell variant that has a popcorn-shaped nucleus (left-bottom of image). H&E stain. Specialty: Hematology and oncology: Frequency: 0.1-0.2 cases / 100000 per year
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.
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 ...
This cell was initially named the Dorothy Reed cell, before later being named the Reed-Sternberg cell. Mendehall effectively disproved the then-common belief that Hodgkin's lymphoma was a subtype of tuberculosis. She also determined that men and young adults are among the most vulnerable to the disease. [2] She published her findings in 1902. [7]
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]
A new approach to a routine blood test could predict a person’s 30-year risk of heart disease, research published Saturday in the New England Journal of Medicine found.
Score X: New areas of uptake unlikely to be related to lymphoma; Scores of 1 and 2 are considered to be negative and 4 and 5 are considered to be positive. "Score 3 should be interpreted according to the clinical context but in many Hodgkin Lymphoma patients indicates a good prognosis with standard treatment." [2]
