The rule of halves. A method of controlling the uniform "cutting-in" of skin biopsies.

This article describes a method of uniform gross-room sectioning of skin biopsy specimens, especially excisional biopsy specimens, to insure even thickness and maximum control of the tissue before paraffinization. This is accomplished by sequentially halving portions of the specimen after each cut as opposed to serially cutting the skin from one end to the other.
