The incubation time in liquid paraffin ought to be extensive sufficient to get enough infiltration, although not any longer than needed in order to reduce extended exposure of the tissue to warmth. For a similar reason, it is suggested that the temperature from the liquid paraffin must be no more than two–four C above the paraffin's melting place.
Re-excision is carried out mainly because there is speedy and comprehensive radial distribute from the first primary tumor which radial spread might not be noticed in the first description of your lesion. The radial distribute may possibly even generate satellite lesions. In all re-excisions, the scar is evaluated thoroughly to determine if residual disorder is existing. Similarly, the new margins are evaluated meticulously for equally surface area satellite and metastatic lesions.
To some extent, underprocessed tissues may be rescued by reprocessing, and a number of reprocessing approaches happen to be explained. In our laboratory, excessive paraffin is faraway from the underprocessed block by inserting the block within the embedding center's molten paraffin for 15–twenty min; the tissue is then replaced from the cassette, set back again during the automated tissue processor starting off in formalin, and reprocessed. The paraffin that still continues to be inside the tissue will deliver some defense versus overprocessing. While reprocessing could possibly be important in a few situations as described over, the caliber of reprocessed tissues is often even now somewhat suboptimal.
