Expanded duct with micropapillary proliferation of enlarged secretory epithelial cells with high nuclear cytoplasmic ratio and enlarged nucleoli. genetics features with cancer {2121}. HGPIN is more strongly associated with intermediate-high grade prostatic carcinoma {708,721,995,1777,2007,2122, 2281}. There is limited data addressing the relationship between the presence and extent of HGPIN in the prostate and the pathologic stage of prostate cancer. It has been reported that the total volume of HGPIN increases with increasing pathologic stage with a significant correlation between volume of HGPIN and the number of lymph node metastases {2122}. Molecular genetic associations of HGPIN and prostate cancer There is extensive literature indicating that HGPIN demonstrates a range of genetic abnormalities and biomarker expression profile that is more closely related to prostate cancer than to benign prostatic epithelium. These studies investigated aspects ranging from cell proliferation and death, histomorphometric analysis and a host of genetic alterations, inactivation of tumour suppressor genes or overexpression of oncogenes {721,1777,2007,2121,2281}. Clinical features HGPIN does not result in any abnormalities on digital rectal examination. HGPIN may appear indistinguishable from cancer, manifesting as a hypoechoic lesion on transrectal ultrasound examination {1012}. HGPIN by itself does not appear to elevate serum PSA levels {57,2144, 2227}. Histopathology Initially, PIN was divided into three grades based on architectural and cytologic features recognizing that the changes cover a continuum. Subsequently, it has been recommended that the classification should be simplified into a two-tier system: low (previous grade I) and high (previous grades II and III) grade lesions {638}. The distinction between low and high grade PIN is based on the degree of architectural complexity and more importantly, on the extent of cytologic abnormalities. In low grade PIN, there is proliferation and "piling up" of secretory cells of the lining epithelium with irregular spacing. Some nuclei have small, usually inconspicuous nucleoli while a few may contain more prominent nucleoli. The basal cell layer A B Fig. 3.62 A Low grade PIN. B Low grade PIN.

Note more benign appearing cytology towards center of gland. normally rimming ducts and acini is intact in low grade PIN. It is difficult to reproducibly distinguish low grade PIN from normal and hyperplastic epithelium {709}. High grade PIN is characterized by a more uniform morphologic alteration. Cytologically, the acini and ducts are lined by malignant cells with a variety of architectural complexity and patterns. The individual cells are almost uniformly enlarged with increased nuclear/cytoplasmic ratio, therefore showing less variation in nuclear size than that seen in low grade PIN. Many cells of HGPIN contain prominent nucleoli and most show coarse clumping of the chromatin that is often present along the nuclear membrane. HGPIN can be readily appreciated at low power microscopic examination by virtue of the darker "blue" staining of the lining that reflects the expanded nuclear chromatin area {294}. Architectural patterns of HGPIN Four patterns of HGPIN have been described, which are flat, tufting, micropapillary, and cribrifrom: nuclear atypia without significant architectural changes (flat pattern); nuclei become more piled up, resulting in undulating mounds of cells (tufting pattern); columns of atypical epithelium that typically lack fibrovascular cores (micropapillary pattern); more complex architectural patterns appear such as Roman bridge and cribriform formation (cribriform pattern). The distinction between cribriform high grade PIN and ductal carcinoma in-situ is controversial (see duct carcinoma in-situ) {288}. In high grade PIN, nuclei towards the centre of the gland tend to have blander cytology, as compared to peripherally located nuclei. The grade of PIN is assigned based on assessment of the nuclei located up against the basement membrane. Histologic variants Signet-ring variant. High grade prostatic intraepithelial neoplasia (PIN) with signet-ring cells is exceedingly rare with only three reported cases {2181}. In all cases signet-ring cell PIN was admixed with adjacent, invasive signet-ring carcinoma. Histologically, cytoplasmic vacuoles displace and indent PIN cell nuclei. The vacuoles are mucin-negative by histochemical staining (mucicarmine, Alcian blue, PAS). A Fig. 3.64 A High-grade prostatic intraepithelial neoplasia, signet ring type.
