Progress in cellular pathology continues, particularly in immunocyto-c
hemistry and in situ hybridisation. However, much can still be determi
ned by the application of special staining techniques, histochemistry
and electron microscopy in the study and diagnosis of disease. This up
date reflects the breadth of technology currently employed in this lab
oratory discipline and covers lipofuscin, intestinal microvillous diso
rders of infancy, blood group antigen expression in pancreas, Epstein-
Barr virus in gastric carcinoma and gene expression, human papillomavi
rus infection, familial multiple endocrine neoplasia, and the investig
ation of death by poisoning.
