You say "they are unable to see the melanocytes". Or is it just the 
melanin granules that are "missing"? Are other cells and structures 
staining normally? Do the granules appear if you use Masson-Fontan or 
some other melanin demonstration technique? Do the problem specimens all 
come from the same source (clinic, surgeon, etc).
Are you sure you don't have a population of albinos in your region?
