Tissue microarrays are a method of relocating tissue from conventional histologic paraffin
blocks in a manner that tissue from multiple patients or blocks can be seen on the same
slide. This is done by using a needle to biopsy a standard histologic section and placing the
core into an array on a recipient paraffin block. This technique allows maximization of tissue
resources by analysis of small core biopsies of blocks, rather than complete sections. Using
this technology, a carefully planned array can be constructed using cases from pathology …
