Immunomorphological study of 216 cases of reactive hyperplasia in lymph nodes

Abstract

In this study, morphological observations were made on 216 cases of reactive hyperplasia (RH) in lymph nodes. For certain cases of the series, E-rosette formation test in cell suspension from lymph tissue, nonspecific acid esterase and double peroxidase-antiperoxidase marking (D PAP) on lymph tissue sections were also performed. According to the major architecture of lymph nodes and cytological features of hyperplastic cells as well as the modern immune function concept, RH was divided into six types, each of which was subdivided into several subtypes, providing respective histomorphological evidences for recognizing the characteristics of RH.
