Loop electrosurgical excision procedure
From Libre Pathology
- Relatively common ~ 25% of cases in one larger series.
- Review the biopsy that triggered the LEEP - check whether it is HSIL.
- Cut levels (x3) on all blocks.
- Flip all the blocks and cut levels (x3) on all the blocks.
- Do a p16 immunostain on the most suspicious block, if the triggering diagnosis was cannot exclude HSIL, HSIL or SCC.
- Sign out the thing as negative - see below.
A. UTERINE CERVIX, LOOP ELECTROSURGICAL EXCISION PROCEDURE (LEEP): - ACUTE AND CHRONIC CERVICITIS. - BENIGN SQUAMOUS EPITHELIUM, METAPLASTIC SQUAMOUS EPITHELIUM, AND BENIGN ENDOCERVICAL GLANDS. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY, SEE COMMENT. B. UTERINE ENDOCERVIX, CURETTAGE: - ENDOCERVICAL MUCOSA AND STRIPPED ENDOCERVICAL EPITHELIUM WITHIN NORMAL LIMITS. - BENIGN SQUAMOUS EPITHELIUM. - NEGATIVE FOR DYSPLASIA. COMMENT: Levels were cut (x3) on all blocks. The blocks were then flipped and an additional set of levels (x3) were cut on all blocks. A p16 immunostain was done on A1. It does not demonstrate high-grade dysplasia. The previous pathology was partially reviewed, and I have no significant disagreement with the findings.
COMMENT: In the context of the preceding tests, no additional levels were cut on the LEEP specimen.
- Cervical intraepithelial neoplasia.
- High-grade squamous intraepithelial lesion (HSIL).
- Negative prostatectomy.
