Context 1

... cHL is characterized by a minority of neoplastic cells (1-2%) named H/RS cells embedded in a rich background composed of a variety of reactive, mixed inflammatory cells consisting of lymphocytes, plasma cells, neutrophils, eosinophils, and histiocytes ( Figure 1A). Thus, the presence of an appropriate cellular background-along with the results of immunophenotyping-is basic for the diagnosis. ...

... only feature shared by NLPHL and cHL is the low number of neoplastic cells. The neoplastic population consists of large elements called lymphocytic/histiocytic or popcorn cells ( Figure 1B) . However, these neoplastic cells have a characteristic profile, which differs greatly from that of cHL ( Harris et al., 2000;Harris et al., 1994). ...
