High-grade prostatic intraepithelial neoplasia and prostate
WebUma nova graduação foi proposta em 1989, onde o PIN foi dividido em dois grupos. O PIN de baixo grau (LGPIN) e o PIN de alto grau (HGPIN) (4). A neoplasia intra-epitelial prostática revela à microscopia, alterações cito-histológicas no epitélio de ductos ou ácinos pré-existentes, com características multifocais. A LGPIN Webwhether a lesion represents grade 2 or 3, it was eventually decided that both grades share the same umbrella of HGPIN, resulting in a dichotomy of either low- or high-grade PIN that is more commonly used today.4,16 Histological characteristics of HGPIN are particularly protu - berant in nature, consisting of neoplastic epithelial cells with it s well known wide area network

PIN has a high predictive value as a marker for carcinoma, and its identification in biopsy specimens warrants repeat biopsy for concurrent or subsequent carcinoma. The only methods of detection are biopsy and transurethral resection; PIN does not greatly … its whateva
