Histopathology Artifacts Quiz
ANSWER CASE 28
The correct answer is not the obvious one a fold in the section but
there are two distinctly different pieces of tissue on this slide.
The tissue in the centre is kidney whilst the other piece is
pitiutary indicating specimen to specimen contamination. This
contamination was not apparent in the block so it is believed that
it occurred either from the edge of a knife which was not cleaned
between specimens or picked up from the surface of a water bath. So
the answer is specimen to specimen contamination but also give
yourself a mark if you suggested that the contamination came from a
knife or water bath.
