- Reed-Sternberg cell
Reed-Sternberg cells (Lacunar Histiocytes for certain types) are different giant cells found on
light microscopy in biopsies from individuals withHodgkin's lymphoma (aka Hodgkin's disease; a type oflymphoma ), and certain other disorders. They are derived from B lymphocytes.They are named after
Dorothy Reed Mendenhall (1874-1964) andCarl Sternberg (1872-1935), who provided the first definitive microscopic descriptions of Hodgkin's disease. [Reed D. On the pathological changes in Hodgkin's disease, with special reference to its relation to tuberculosis. Johns Hopkins Hosp Rep 1902;10:133-96.] [Sternberg C. Uber eine eigenartige unter dem Bilde der Pseudoleukamie verlaufende Tuberculose des lymphatischen Apparates. Ztschr Heilk 1898;19:21-90.]Reed-Sternberg cells are large and are either multinucleated or have a bilobed nucleus (thus resembling an "owl's eye" appearance) with prominent
eosinophilic inclusion-like nucleoli. Reed-Sternberg cells areCD30 andCD15 positive, usually negative forCD20 andCD45 . The presence of these cells is not pathognomonic for the diagnosis of classical Hodgkin's lymphoma. They can also be found in reactivelymphadenopathy (such asinfectious mononucleosis ,carbamazepine associated lymphadenopathy) and rarely non-Hodgkin lymphomas.External links
