ABSTRACT

The immunohistochemical stain has been rapidly embraced as an integral and often indispensable component of histological assessment. It is a histological assay that is inextricably a part of morphology. For this reason we proposed in 1998 the term “immunohistology” in preference to “immunohistochemistry” and “immunocytochemistry” in order to highlight this important attribute 1 . Alternative appellations like “immunohistopathology” 2 , and “immunomicroscopy” 3 were subsequently proffered in recognition of the importance of correlating morphologic features with the immunological assay.
