===Gross processing=== | |||
*Ensure that the biopsy is properly '''fixed''' (generally at least 2 hours). | |||
*'''Measure''' length and diameter of each fragment. | |||
*If the biopsy is received in a zinc-containing fixative, '''rinse''' it for about 2 minutes, such as placing the cassette in a container under running water (and block any sink enough so that the cassette won't float away). | |||
*Put in '''decalcifying''' solution, generally about 15 minutes, and palpate the specimen to check whether it is still firm. If it is, decalcify another 5-10 minutes and check again. Rather have it a little bit too soft than a little bit too firm. | |||
;Gross report example: | |||
