====Multiple lesions==== | |||
In the context of several (large) lesions it is good practice to: | |||
*Measure the distance between the lesions.‡ | |||
*Take sections showing the interface between the lesions (if possible) ''or'' non-lesional tissue between the lesions.‡ | |||
*Document with images (photographs). | |||
Note: | |||
*‡ If the tissue is studded with too many lesions to count this is impractical. Practically, four or five lesions is a reasonable limit; if more lesions are present the focus should be on (1) the largest lesions, (2) the distance to the margins for the largest lesions and the closest (smaller) lesion(s). | |||
==Report organization== | |||
*A gross report that follows the order in which things are done may reduce omissions. | |||
**The cut-up generally is: (1) identification - patient/specimen type, (2) orientation & measurement, (3) external description/assessment, (4) painting, (5) opening, (6) internal description/assessment, (7) internal measurements, (8) blocking. | |||
**Generally, gross report elements are found in the order they are done at the grossing bench, e.g. identification patient/specimen type is first, blocks are last. | |||
