Histopathology Of The Hepatocytes In Src Overexpressing Transgenic Abnormal p53 (p53abn) immunohistochemical (ihc) staining patterns can be found in vulvar squamous cell carcinoma (vscc) and differentiated vulvar intraepithelial neoplasia (dvin). they can also be found in the adjacent skin that shows morphology that falls short of the traditional diagnostic threshold for dvin. vulvectomy specimens containing human papillomavirus–independent p53abn vscc with. Seventy three human papillomavirus independent p53abn vsccs were included. half (35 73, 48%) had documented an in situ lesion in the original report. the use of p53 ihc staining identified 21 additional cases (29%) with the p53abn in situ lesions that were originally unrecognized.
Immunohistochemical Staining Of Prostate Cancer And Bph Nuclear The p53abn in situ lesions at a margin were confirmed to have tp53 mutations by sequencing. p53 ihc staining identified morphologically occult p53abn in situ lesions surrounding human papillomavirus–independent vscc. p53abn ihc staining at a margin was associated with a 3 fold increased risk of local recurrence. The two types of hpv independent tumours showed worse rfs in the multivariate analysis (hazard ratio [hr] = 3.63; p = 0.023 for the hpv independent p53 normal vscc and hr = 2.78; p = 0.028 for the. Skin. this mutation associated p53 ihc staining pattern also frequently and unexpectedly extended to the surgical margins. therefore, we hypothesized that mutation associated p53 ihc staining in the skin surrounding the vscc (“p53 abnormal field of dysplasia”) is clinically signi ficant and could potentiallyexplain the. Doi: 10.1016 j.modpat.2022.100010 corpus id: 255656225; p53 abnormal "fields of dysplasia" in human papillomavirus independent vulvar squamous cell carcinoma impacts margins and recurrence risk.
Immunohistochemical Analysis Of Pdcd4 Shows The Corresponding Skin. this mutation associated p53 ihc staining pattern also frequently and unexpectedly extended to the surgical margins. therefore, we hypothesized that mutation associated p53 ihc staining in the skin surrounding the vscc (“p53 abnormal field of dysplasia”) is clinically signi ficant and could potentiallyexplain the.

Vulvar squamous cell carcinomas and their precursors are currently classified by the world health organization based on their association with high risk human papillomavirus (hpv). hpv independent. We performed p53 ihc in a series of 779 hpv independent vscc with adjacent skin and evaluated the ihc slides following the newly described classification. some 74.1% invasive vscc showed abnormal p53 ihc staining. a skin lesion was identified in 450 cases (57.8%), including 254 intraepithelial precursors and 196 inflammatory reactive lesions.
