Histopathology of high-grade prostatic intraepithelial neoplasia (HGPIN) with typical features, H&E stain. [6] High-grade prostatic intraepithelial neoplasia. HGPIN typically has one of four different histologic patterns: [2] tufted (fascicular patterning) micropapillary, cribriform and, flat. Its cytologic features are that of prostatic ...
However, high magnification (right image) shows the key feature of prominent nucleoli (visible at 200x magnification to make the diagnosis of "high-grade"), as well as other typical features of HGPIN. Reference for features: - Margaret Sanders, M.B.B.Ch., Murali Varma, M.B.B.S.. High grade prostatic intraepithelial neoplasia (HGPIN).

C. High-grade dysplasia, here called high grade squamous intraepithelial lesion (HSIL) D. Squamous cell carcinoma , infiltrating the stroma (middle and left in image), and HSIL (right in image) Epithelial dysplasia , a term becoming increasingly referred to as intraepithelial neoplasia , is the sum of various disturbances of epithelial ...
A histopathologic diagnosis of prostate cancer is the discernment of whether there is a cancer in the prostate, as well as specifying any subdiagnosis of prostate cancer if possible. The histopathologic subdiagnosis of prostate cancer has implications for the possibility and methodology of any subsequent Gleason scoring . [ 1 ]
The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3]
Hematoxylin and eosin stains from different sections of a single diffuse intrinsic pontine glioma specimen, showing low-grade (top) and high-grade (bottom) areas. In pathology, grading is a measure of the cell appearance in tumors and other neoplasms.
Additionally, the tumor proliferation index has been used to predict the response to systemic chemotherapies in patients who are receiving neoadjuvant systemic therapy where patients who have tumors with high tumor proliferative index respond better to systemic cytotoxic therapies than those who have tumors with a low tumor proliferative index.
